A Note On High Sierra Compatibility with Third Party SSDs

Some users have reported compatibility issues with third party SSDs when attempting to install or run macOS 10.13 High Sierra. In testing, we have identified a related issue with our Aura SSDs. Apple is aware of these issues and we are working with them to resolve this as quickly as possible. Thus far we believe the issue is limited to Aura SSDs  for only these Mac models:

  • MacBook Air (11-inch, Mid 2013)
  • MacBook Air (13-inch, Mid 2013)
  • MacBook Air (11-inch, Early 2014)
  • MacBook Air (13-inch, Early 2014)
  • Mac Pro (Late 2013)

The number of OWC customers affected by this issue is limited, but we take every issue very seriously. We have sent communication to our customers that purchased these specific SSD models, and have been working directly with any customers affected. For those who have not attempted to upgrade yet, we recommend using macOS 10.12.x Sierra or earlier on your OWC Aura SSD.

If you have any questions, comments, or concerns regarding the upgrade to macOS 10.13 High Sierra, feel free to contact our award-winning customer service team.

  • I have Mac Pro (Late 2013) with Aura SSD.
    Which of your SSDs is compatible with MacOS Catalina & above for this Mac?

  • I have an OWC Aura Pro X running on a MacBook Pro Late 2013.

    It has worked perfectly well for 2ish years, but now, occasionally the computer will not boot and/or just die and a folder with. a flashing question mark shows up!

    It seems strange that this is an intermittent issue – usually if it dies I wait a while and turn the computer back on and works again.

    Any ideas?

  • I have a Mac Pro late-2013 with a 2T Aura SSD. Over time I’ve upgraded OS X’s from High Sierra through Catalina by replacing the Aura SSD with the original Apple SSD, update the SSD and put it into an external case, boot off the updated external and clone back to the re-installed Aura, and finally after rebooting off the updated Aura, use Migration Assistant to re-install data.

    Q: is this routine also needed to upgrade from Catalina to Big Sur?

    • Yes the routine is still needed to upgrade to Big Sur. The only thing to watch for is which version of the software they recommend for cloning the upgraded stock SSD to the Aura. When I did mine I had to grab the beta version (download the free version they provide, go into preferences in the app and then select the option to install beta versions). Only other snag I ran into was manually setting the device/path for Migration Assistant to pull from my Time Machine backup on my home network.

      • Thanks Paul.
        While chasing this issue, I text-chatted with OWC support who said my Aura 2T SSD wasn’t compatible above High Sierra because the SSD was RAID-based modules. He recommended I upgrade to 2.0TB Aura Pro X2 SSD for some $400+. No problems on my end up through Catalina; does this make sense?
        That aside, is the upgrade to Big Sur worth the effort? On an upgraded Mac Mini, I only see user-interface modifications (and minor ones at that). Are there meaningful security or technological reasons for this update?
        Thanks in advance for your thoughts.

        • I have the 4TB Aura Pro for my trash can Mac, so I can’t speak in regard to the difference between the Pro/non-Pro version.

          Since I’ve been through this upgrade process so many times now (I’ve had the Aura Pro for quite a while) I can disassemble/reassemble my Mac in no time and rip through the steps quickly. It’s the migration from the Time Machine backup that takes the time.

          For me, I’m enjoying the upgrade to Big Sur. New icons, updates to Messages to bring it more in line with the iOS version, etc. Obviously at some point Apple will drop supplying security updates to Catalina, but that won’t be for a while. Big Sur has been stable for me, and they (literally) just released another point release for it.

  • I encountered issues with an Aura 2TB SSD in my Mid-2014 MacBook Pro Retina, on High Sierra, with Apple 500GB SSD.

    Many painful steps later I: 1. upgraded to Mojave on the old SSD; 2. Created a bootable USB with Mojave; 3. Moved the Aura 2TB to the Mac and the old Apple SSD to the Envoy enclosure; 4. booted (using Cmd-R) and then installed Mojave on the 2TB from the USB key; 5. replaced USB key with Envoy external drive, rebooted, and used Mac Migration to copy files from the Envoy (the old 500GB SSD).

    Before this I had tried (after step 4) to recover from a Time Machine backup I made but after 24 hours of TM in “Preparing Backup”, I cancelled this and went to the step 5 above.

    So far (fingers crossed!) I’ve been running 2 days on the Aura 2TB SSD with no problems.

    • I’ve successfully upgrade to High Sierra, then Mojave and now Catalina using the 4TB Aura Pro in my desktop Mac Pro (trash can Mac).

      Make sure I have an updated TimeMachine backup.
      Re-install the original SSD into the Mac Pro.
      Upgrade the original SSD to the latest OS version.
      Put the original SSD back into the external enclosure.
      Re-install the Aura Pro back in the Mac Pro.
      Boot up off of the external enclosure (original drive)
      Use a utility to image the external drive (upgraded to the latest version) onto the Aura Pro (installed internally).
      Reboot using the Aura Pro, then either restore from TimeMachine or use the Migration Assistant. (I think the last time the Migration Assistant was the way to go.)

      I can’t remember offhand the utility recommended for imaging the Aura Pro from the original drive. While a pain for something that should be dead simple, the process works.

      I’ve not experienced any heat issues or problems. However, I do recognize that my Mac Pro is getting up in age (although still an awesome system!) and with the release of the new Mac Pros don’t expect it will be supported for much longer.

      • I had a problem with upgrading to High Sierra on my 1TB Aura SSD. It took several weeks to get suggestions back from OWC customer service beyond the “We know we have a problem and are working with Apple to resolve it” message. It turns out the the Apple OS upgrades now update the machine’s firmware and you can’t do that due to shortcomings in the Aura SSD. After several tries with similar complex instructions to swap SSDs install the upgrade etc. I finally got it to work. When Mohave came out I the problem reoccured and when I asked Customer service if I was going to have to go though this process every time Apple upgrades it’s OS, I was told that it would seem so. Given that the process didn’t always work, I decided to just stay with High Sierra. If I eventually need something in a later OS upgrade, I’ll look for a different SSD that doesn’t have this issue. I am fairly certain that Apple is not working on any solution to correct Aura SSD issues.

  • I have a 2T Aura installed in a Mac Pro 2013 and have successfully upgraded operating systems through Mojave. A couple of months ago I was about to repeat the process of swapping out with the Apple SSD (for the firmware update ?) for Catalina when I got the OWC-support advice NOT to upgrade until they have tested for compatibility.

    Not sure where to ask, has the compatibility with Catalina been tested, and if so, what’s the installation process starting from Mojave?


      • Mark:

        Thanks for the reply. I will call to discuss with support, but the last two times I called on this issue, I got completely conflicting answers: Initially “go ahead and repeat what’s worked for you in the past”, and then later when I wanted a refresher on the procedure … “we do not advise upgrading to Catalina until Mac Pro with an Aura SSD has been thoroughly tested for compatibility.”

        How do I make sure I’m talking to someone well-informed on this arcane hardware issue?


  • Been dealing with his issue for 2-3 years now on an Aura 4TB Mac Pro SSD. Spent countless hours – no, days – troubleshooting and googling. Unbelievable something that cost that much has caused this many headaches with no actual solution or firmware update from OWC. A few days ago I had to jump through hoops – once again – because Mojave would refuse to install. Had to pull the Aura, swap in the Apple SSD, install Mojave, clone the install to a USB stick, swap in the Aura again, format it APFS, clone the USB stick to the Aura, and cross my fingers that it would boot. Thankfully it worked. This, after literally 10 years of buying different generations of SATA SSDs from OWC for different machines, most of which failed within a few years. I’m so absolutely fed up and done with OWC it’s not even funny.

  • What a nightmare I have had with 480GB OWC Aura Pro Xb SSD. Both in High Sierra and Mojave on a mid-2013 Macbook Air !!! Kernel panics constantly, eventually disk file corruption when it is actually able to boot up. And what is up with the huge chunk of thermal putty attached to it when the original Apple SSD doesn’t need that? What a disaster. I had to send it back. Now using the original Apple SSD and it runs much cooler and back to rock-solid reliability. very sad.

  • I replace my 2015 MacBook Pro hard drive with the OWC 1TB Drive. I get a File and ?. I tried numerous fixes and nothing worked. I reinstalled the old drive, upgraded to the latest software and Mojave. Reinstalled the drive, same thing. I’m so beyond frustrated. I have followed every possible way to fix this problem. I spent most of the day on it reading every possible solution. I’m ready to use it as a frisbee for my dog.

  • I have a 2013 Mac Pro cylinder 6,1 with the OWC 2TB SSD as the internal drive and am unable to upgrade to High Sierra. I have done a firmware update but still am unable to update the Mac Pro.

  • Hi.
    I have a Mac Pro late 2013 running Mojave10.14.1, just purchased the 1TB Auro Pro X drive. System does not recognize the drive and to make matters worse as long as the drive is installed the system refuses to boot into recovery mode.

    So far not heard much back from OWC.

  • I had followed the process to update the firmware when high sierra was released for my Mac Pro 2013 with the Aura 4 TB SSD. The firmware is installed through a Marvell software RAID manager. I was able to get the Mac Pro to update and run properly but maintained in in HFS+ as I was unable to format the drives as APFS and I was concerned about APFS being stable enough for my configuration. Yesterday I just updated to Mohave and voila…it updated without a hitch and now my boot drive is now APFS with an indicator that its “shared by 4 volumes” in Disk Utility. So far so good…fingers crossed it stays stable.

  • Aura SSD Firmware Update:

    Jarrod Rice Thank you for your help.
    followed your steps and it worked with no problem (Late 2013 Mac Pro Aura SSD 4TB).
    I am now running 10.14 with APFS Volume on my Aura SSD 4TB.
    Again Thanks. William

    • Hi William

      Could you by any chance advise me what you ditto get this working? I can’t seem to get anywhere with thisissue. I have a Mac Pro late 2013 and Aura SSD 1Tb.

      Appreciate your help.



        • William, the firmware updater specifically says “This specific firmware update process does not apply to Mac Pro customers.” Are you saying that, in fact, the firmware updater DID WORK on your Mac Pro’s Aura 4TB SSD?

          • I used the firmware updater on the link above on a Mac Pro with a 4TB Aura SSD, and was successfully able to install Mojave 10.14 without a problem. Thus far my system appears stable; crosses fingers.

            • I tried to follow the directions, but in the menu where they say to select “update” there is no update option. So how do I update on a MacPro?

            • Hi – I was successful on my MAC PRO 2013 – not not do the Firmware update, just upgraded the APPLE SSD and then Carbon Copied over to the OWC AURA 1TB.
              Question – HIGH SIERRA has a patch – can I update via APPLE ‘s way going forward?

  • I have this problem. Funny that OS X refuses to install, but didn’t refuse to upgrade to High Sierra. I ended up with an un-fixable file system error. Trying the approach of installing previous OS

  • I’m a developer here as well. What can I do to fix this issue? It is especially annoying because I’m running high Sierra already and I’m trying to update to mojave. Does anyone have a solution?

  • Trying to install the Mojave developer beta on my MacBook Pro with a 1Tb OWC Aura SSD.
    Even though I am attempting the Mojave install, I am getting the message:
    MacOD High Sierra cannot be installed because the third-party storage installed in your Mac is not compatible. Please contact the supplier directly for assistance.

  • I have a 13 inch MacBook Pro with the 1G Aura SSD installed. I tried to wipe it and put a fresh install of High Sierra 10.13.3. No Joy. Got a message that my SSD was incompatible. Fortunately I had a backup, but it took 18 hours to restore from a USB 3 drive.

  • I have a Macbook Pro 15 Retina and the only way the drive worked was to install a fresh copy of High Sierra from USB and then migrate the data from the apple drive or time machine.

  • I just installed OWC aura pro ssd to my MacBook Pro 2013, however it seems to reboot two times by itself everytime I turn it on. I don’t know if this cause by the ssd or if it just the way it is! Also the SSD has been causing my MacBook Pro to over heat which forces the fans to run 80 percent of the time.

    Do you think you guy have any solution of that?

  • Once again issue related to the compability. In my case, the screen displayed the following quote: “macOS Sierra cannot be installed because the third-party storage installed in your Mac is not compatible. Please contact the supplier directly for assistance”… so I do.

    By the way, I had already had some issues in the past which I had resolved by installing the original one into the MacPro (2013)…. however and very saddly, the problem seems to arise once again

  • I purchased a ssd for 13″ MacBook Pro Retina display (2013) back in Nov/Dec. It has been working fine until today. When I attempt to reinstall IOS over the web, I get an error message that says my hard drive is not compatible? I had just upgraded to the newest version of High Sierra.

  • Just a note for everyone here, I was having trouble with installing 10.13. When I re-installed the original SSD (including the screws), I got a black screen and the fans spun up. I was still under applecare, so I took it in and they replaced the logic board, I/O board, and I/O flex cable. These mac pros have a high failure rate, so if you are having problems, and have the original SSD and applecare, it might be worth it to have apple check it out.

  • Having problems getting High Sierra to load on a 1 tetrabyte mercury Electra 3G kit I installed in my late 2009 iMac.

    Any thoughts?

    $350 and dead in the water


  • I have a Macbook Air (13 Inch Early 2015) and I just bought 480 GB OWC Aura Pro Xb SSD. I’m running High Sierra and the drive can’t be found. So expand your list to include the 2015 models

  • I have a mid 2014 macbook pro with a 512 ssd. I want to install the 2TB ssd. Any issues, problems that you now know about after several months of sales?

  • I have used a slightly less complicated—at least for me—way to upgrade OWC Aura SSD to High Sierra. The result is an OWC Aura SSD on a APFS volume, that I was able to upgrade yesterday to 10.13.3 without any problems. Here is the process I found on another forum that worked for me:

    – Before starting, make sure you still have the original Apple SSD that your computer came with, as well as any screws that were removed during the OWC Aura SSD installation. If you don’t have them, then these instructions will not work.
    – Use Carbon Copy Cloner (CCC) to make a backup clone of your OWC Aura SSD (OS 10.12.6) startup disk to an external drive. Of course, there are other cloners out there, but CCC offers 30 day free trial, which was incentive enough for me to use it. This step is not necessary, but is certainly recommended in case something goes wrong.
    – Put the original Apple SSD into the Envoy enclosure and connect it to your computer.
    – Use Carbon Copy Cloner (CCC) to make a clone of your OWC Aura SSD startup disk (running OS 10.12.6) to the original Apple SSD. (In my case, I had to temporarily delete my documents, downloads and iTunes library folders, as I had too much data for my 256 GB factory Apple SSD. Once the entire process was completed, I copied these files back from the backup I made in step one.)
    – Shut down.
    – Remove your OWC Aura SSD from your computer and replace it with the original Apple factory SSD from the Envoy enclosure. Make sure to replace not only the SSD, but also any screws which may have been removed during the OWC Aura SSD installation.
    – Restart your machine as you hold down the alt/option key to see the boot disk options. Chose the original factory disk.
    – When the computer finishes booting from the original Apple factory SSD, go to App Store and upgrade to High Sierra. During this upgrade, that SSD will become an APFS volume.
    – Shut down.
    – Remove the original Apple factory SSD from your computer and replace it with the OWC Aura SSD.
    – Put the original Apple SSD back into the Envoy enclosure and connect it to your computer.
    – Restart your machine as you hold down the alt/option key to see the boot disk options. Chose the original factory disk, which is now in the Envoy enclosure.
    – When the machine finishes booting, you can ignore iCloud passwords and Dropbox passwords if they are asked for at this stage.
    – (Although not it was not a part of the original instructions, at this stage I chose to reformat my OWC Aura SSD to APFS Volume.)
    – Open CCC and clone the external Envoy disk (at this point housing the original Apple SSD with OS High Sierra on it) to the internal OWC disk. If CCC asks you to create the Recovery Partition on the OWC drive, say yes and create the Recovery Partition on the new drive.
    – Once the cloning is finished, restart normally. Your computer will boot from the internal OWC drive running OS High Sierra on a APFS Volume.

    I hope this is not too complicated and that it helps someone. If not, it will not be the only useless information on the internet.

  • Hi, I have a Mid 2011 MBA 13″, installed OCW 480 Aura Pro 6G (rev 600 ABBFO) and running OS 10.12.6. When prompted to update to OS 10.13, the process starts but then aborts. I tried several times but no luck so far. Please advice

    • managed to update to 10.13.3 without swapping hard drives. –
      1.) I updated to latest security update on 10.12.6
      2.) made clone with C.C.C
      3.) checked if my firmware on the Aurora needs updating, it did. FOLLOW INSTRUCTIONS CAREFULLY on OCW site.
      4.) after updating firmware for hard drive I tried once more to install HighSierra. This time it worked and files changed to APFS. Had to do the resetting of iCloud account. A note the the hard drive is optimizing did come up. HURRAY it worked. Hope you can do the same by installing the firmware rev 603 ABBFO dated 2015

      • I don’t think this works with the MacPro. We are still waiting for a fix other than putting in the old SSD which many of us don’t have.

  • Will a 2015 Macbook Pro with a 1tb drive from Aura ( or another 3rd party manufacturer) be able to run Sierra?

  • I solved this issue with a 4TB Aura SSD on a 2013 Mac Pro but took some hacking to get it to work.

    Backstory: I had it as my system book drive, formatted HFS+ with macOS Sierra in early 2017, and somehow successfully upgraded up to macOS High Sierra 10.13.2 with no issues. Now (early 2018) I decided to convert the drive to APFS by rebooting into the recovery partition and converting it in Disk Utility. It worked, but at the very end displayed an error related to not being able to “bless” the drive as a bootable volume. Upon reboot, the system would not boot into macOS – it just stayed on a black screen.

    The way I ended up solving this was to boot back into recovery, launch Disk Util and unmount the system volume, launch Terminal, and run the “bless –device” command to make it bootable. (Google it to find out the proper syntax). The “bless -mount” command did not seem to be working, but the device command above did.

    (It should be noted that beforehand, I did swap in the original Apple SSD and do a fresh High Sierra install on it to try and coerce whatever ‘firmware’ to install that people in the comments are talking about. I’m not sure if that helped, but I suspect it didn’t have anything to do with fixing my problem.)

    Any way, I hope this helps someone. I spent several hours chasing this issue before I solved it.

  • Dear Team,
    I have a Mac Pro (Late 2013) with 1 TB Aura SSD installed. I am interested, therefore, in any news regarding a resolution of this firmware problem.
    Should I be trying Anthony’s process??
    Viz…MacPro Late 2013 Aura SSD. Now running 10.13.1
    Achieved this by re-installing the original SSD, installing High Sierra, reinstalled Aura SSD and installed High Sierra.

  • I have a Mac Pro (Late 2013), have purchased an Aura SSD and have not received any notifications. At any rate, it is almost 2018 now and no solution yet?

  • I COMPLETED SOME YEARS AGO A MERCURY ELEKTRA 120GB SSD FOR MY MACBOOK PRO EARLY 2011, BUT WITH THE ULTIMATE UPDATE OF HIGH SAW (10.13.2) MY macbook suddenly turns off when disconnecting the battery charger. Any advice about my problem ???

  • I previously left wrong information. Actually, I have an OWC 960 GB SSD. Fortunately, I had time machine backups and could get back to Sierra after High Sierra made my high priced internal SSD unusable. When will this be fixed?

  • I have a new issue. If the Aura SSD can not solve the hardware compatibility, upgrading to macOS 10.13 High Sierra’s APFS can only replace a new SSD. The question is, how to replace the 2tb Aura SSD again, is there a HDD Enclosure compatible? Into a thunder and lightning 2 interface mobile hard disk. Please tell me if any, thank you

    • Dear Sir, on Dec 18th you posted, “Today, my Mac Pro (2013) Aura SSD 2TB is the perfect solution for installing macOS 10.13.2 High Sierra. No need to replace the original APPLE SSD, make the boot disk, right in the Aura 2TB SSD, direct disk formatted APFS format, and then a new installation, everything is going well. The problem seems perfect! At least on my Mac Pro this is the case.”

      My question to you sir, is could you be more specific on making your boot disk, as well as possibly some detailed instructions? Thank you in advance

  • Is this OWC Aura SSD problem with macOS 10.13 High Sierra APFS due to these drives being RAID 0 inside?

    If they are RAID 0, that should have been fully disclosed in the product specifications. Purchasers have the right to know what they are buying. Some manufacturers do not disclose it, and that only fires back to them when it is discovered later on by others. Examples include (undisclosed RAID 0 inside):

    LaCie Bolt3
    SanDisk 900 Extreme

    RAID 0 may be great for some applications, but not for others. For instance, it increases more than twice the failure rate if one of the disks inside or the controller fails. Besides this issue with APFS.

  • I brought a OWC 480GB Mercury Extreme® Pro 6G SSD 2.5″ Serial-ATA 7mm Solid State Drive and when I update to High Sierra start to work really slow and then the computer stop recognize any drive (even if i connect ir via USB)

  • I brought a 1TB Aura SSD for my mothers MacBook Air 2012 model.
    I believe it tried to automatically update her to High Sierra and then failed. I believe this problem extends further then just 2012 models.

  • High Sierra has released an update to 10.13.2。 Excuse me, Aura SSD has a new driver firmware?can be converted to apfs format file system, if not, or to stay at 10.12.6

  • Hello from Austria – I just came upon this place after failing to install HS on my Mac Pro 2013 with a 4TB Aura installed – as apparently everyone else with the same or similar setup. Looking forward to have this issue fixed in the same professional way OWC usually fixes issues…….

    • I used the procedure that Anthony described on my Mac Pro with a 4tb aura and it worked. There are still some intermittent boot and coming out of sleep problems. It did not convert to the new file system.

      Here is Anthony’s process:
      MacPro Late 2013 Aura SSD. Now running 10.13.1
      Achieved this by re-installing the original SSD, installing High Sierra, reinstalled Aura SSD and installed High Sierra. That was it.
      Yes many backups and great care all done very slowly with full erase and installs, but looking back it worked exactly as “documented” which supports the thesis that installing the original SSD allows a firmware update to complete, which then allows everything to run smoothly with the Aura SSD.
      I observe that ANY Apple SSD may suffice, such as one borrowed if the original is no longer available because it is the firmware update that it facilitates that matters, not the rest of the associated OSX install.

      • Are you saying this resulted in APFS on the Aura SSD? That is not supposed to happen, and did not happen when I did the same thing.

        • The process worked for me and have APFS on Mercury Aura Pro 480GB in late 2012/Early 2013 Macbook Pro Retina 15″ (so I can go to Pro X even if I wanted).

          First, cloned latest OS (El Capitan in my case) from MBP to original Apple 256GB Module. Attached via USB in Envoy case.

          Second, installed original Apple 256 module back in MBP and upgraded to High Sierra (was converted to APFS)

          Third, put OWC 480 Aura Pro back in MBP and installed High Sierra again. Worked without a hitch and came up as an APFS drive. I am able to CMD-R to bootable recovery if needed, or Option (boot to alternate drive)..

  • Same thing happened on my MacBook Air (11-inch, Mid 2012). Two times I ended up with a corrupted hard drive since installing High Sierra. The first time I ended up with the MBA not being able to locate an internal drive (Disk Utility could see both the main drive and recovery partition but could not mount them). Last night, the MBA now gets halfway through the boot up process but then shuts off. Both occurred on the reboot following an OS update restart.

  • I have had two instances of the OWC upgraded SSD in my MacBook Air (11-inch, Mid 2012) becoming corrupted. I had it installed in the last year or two. No problems until I moved to High Sierra. Both problems occurred on the second boot following an update (i.e. not the restart following an update install).

  • On the same boat in regards to this issue and only JUST found this announcement. Hoping for a speedy fix too. This has been a problem for so long now. Some updates and feedback would be nice.

    Thanks OWC.

  • There is a new update (6 December 2017) !! Please, if someone is willing to check whether it works, let us know something!!

    My device: MacPro (Late 2013)

    • Noper, my $2000 plus OWC again, died like a big dog when I attempted it. If you look at the details of what is fixed there is no mention of any update to SSD. For new people coming in, you get the impression the fix is imminent while in fact there has been nothing done in months and knew about it in beta.

  • My MacPro 2010 Quad Xeon is having major issues with both of my OWC SSD drives – Mercury Pro Extreme 6G 250Gb – the problem happened immediately after upgrading to High Sierra – would be nice if you had emailed in advance – i have 2 of these? please help.

  • May you be so kind to tell me whether will or will not have got a solution for all of us in the following days or the next update, please? I have been waiting for a long time…

  • There is no problem to clean install HS on ANY OWC Aura drive in ANY possible MB Air / Retina config . Formated APFS , of course . Whole process take aprox. 30 minutes to be on clean HS with really simple hack. Tested especially on MB Air mid 2013 too.

    • Does this simple hack also work on a late-2013 MacPro with an OWC Aura SSD? If so, can you tell us more, or link us to a page that explains how to do this? I have managed to upgrade to HS, but not with APFS so far.

  • A friend is selling a Aura SSD 1TB from his Mac Pro 2013. I’m toying with the idea of getting it as I’m still running El Capitan and might upgrade to Sierra at some point, I can then pass on High Sierra for a bit on the off chance somebody has a simple upgrade path in the future.

    BUT, assuming they don’t and this issue persists, can the Aura SSD 1TB For Mac Pro be mounted in an external housing that I can tag along with my Mac Book Pro 13 Retina as an external drive??

    • Steve,
      Yes you can, but the edge slot of the drive is Apple proprietary not standard M.2. Googling external enclosure for Apple SSDs points at a few pages of OWC links. OWC may be the only one that sells compatible external enclosures due to the slot pinout.

  • MacSales,
    It’s been over 2 months since the release of HS, are you any closer to finding the solution? My company IT will soon REQUIRE High Sierra for tool compatibility and security (despite the little root issue recently found).
    I have not received any update since the initial email stating there was an issue. This is not really working directly with affected customers and being disingenuous is not a direction you should be going. I dropped $1600 on your product.
    If the best answer turns out to be that the Aura, HS, and MacPro(6,1) are not 100% compatible (where not having APFS is a showstopper). Then so be it, just state the fact and move on. Of course, the “move on” depends on how well you want to handle the PR firestorm of dissatisfied customers.

    • I would add to your comment that the beta to HS was available even few months before the release and the problem was identified well before the release date. So actually it has been 4-5 months. The fact that people posted workaround (with first install on original ssd) indicates that it’s not compatibility issue. It should be just firmware upgrade step before the os installation.

      • I am happy to say that I found a solution for the High Sierra/OWC Aura Drive 480 GB conflict. I called the OWC Tech support after I spent numerous hours with Apple Tech support options, and there is an update fix that the OWC technician walked me through. The install took a considerable amount of time, with some hick-ups and false completion signals, but it eventually completed successfully. Let the technician walk you through it, since there are a couple of tricky instructions, until the install step, and be patient with the process.

        • Dear Manny, would you be so kind as to be more specific and perhaps detail step by step what you did in point form? Thank you in advance.

        • I don’t know a more vague reply could be written. What at least in general terms did you have to do? How is it different from the past “fixes” posted here?

  • I have an Aura 2 tb installed in late 2013 Mac Pro. I, too, am unable to update to 10.13. Please advise by email when fix is available.

  • Dear Madam or Sir,
    “We have sent communication to our customers that purchased these specific SSD models, and have been working directly with any customers affected”.
    Really ? Not for me !
    Please let me know when I will be able to take advantage of High Sierra on my SSD Aura 1 Tb.
    Thank you.
    Alain Pilorget

  • I have the Mac Pro (late 2013) and have been unable to upgrade to macOs 10.13 High Sierra. What can be done? How long a wait? You have been responsive and great, don’t fail now.

  • Does anyone at OWC monitor or interact on this blog or do you just enable it as a place where customers can share their pain and disatisfaction as your ignore the issue? Having been an OWC customer for many years your lack of engagement with your customers here has really reduced my previously sterling opinion of you as a company. Buck up on this OWC and at least keep us current that you and Apple are working on this with some indication of when next we’ll see an update from you (preferably a solution)!

  • I got no email notice of High Sierra problem. I got many sales promotion emails from OWC Larry. I am staring at a big [?] now, won’t boot.

  • In accordance with owc guidelines, I swapped the OWC Aura SSD from the Mac Pro and replaced the original Apple 512GB SSD, and then successfully installed macOS 10.13 High Sierra, and confirm that the file system has been converted to APFS. I did a backup and then re-installed OWC Aura SSD, the recovery is smooth, but the file system is still HFS +, the file system can not be converted to APFS regardless of the cloning or recovery, and macOS 10.13 High Sierra can only be run under HFS +. I think it is OWC Aura SSD firmware is not compatible, waiting for the new firmware may be very far, I am frustrated, looking forward to improving support as soon as possible

  • Please let me know when there is an official solution for the “High Sierra installation on an Aura SSD” problem. I put a 1 Tb Aura SSD on a mid-2013 MacBook Air about a year ago, and High Sierra installations always fail with a “firmware problem” error message.

  • The aurora SSD I had installed in my 2015 MBP 15 seems to have caused a similar issue. I have gotten “Couldn’t Complete Copy” errors whether trying to upgrade by the app, or installed from USB. Now my system is useless and wont install or power on.

    • Hi Steve, that’s not good, my sympathy. Have you tried “internet recovery”? (alt-cmd-r during startup) I used this alone while doing these (clean install) updates because everything else failed one way or another (MacPro not Macbook) I also first re-installed the original SSD, clean installed HS on that, removed it re-installed Aura and then clean installed HS to that. The theory being that this process updates the firmware somewhere which then allows the Aura update to proceed. Humble apologies if this doesn’t help. Anthony

  • How come there is no solution. I think I will return to you the SSD and buy another one at the Apple Store. My MacBook Air Mid 2012 is not working since I upgraded to High Sierra. I dont have the old SSD. :-(

  • Not sure where my earlier post went to but I did the workaround and it worked BUT now the 10.13.1 update is not installing which I’m sure is related to this. Be sure to do a back up before updating to High Sierra!

    • MacPro Late 2013 Aura SSD. Now running 10.13.1
      Achieved this by re-installing the original SSD, installing High Sierra, reinstalled Aura SSD and installed High Sierra. That was it.
      Yes many backups and great care all done very slowly with full erase and installs, but looking back it worked exactly as “documented” which supports the thesis that installing the original SSD allows a firmware update to complete, which then allows everything to run smoothly with the Aura SSD.
      I observe that ANY Apple SSD may suffice, such as one borrowed if the original is no longer available because it is the firmware update that it facilitates that matters, not the rest of the associated OSX install.

      • Using the procedure you described, I was able to update to High Sierra on my Mac Pro late 13 with the 4 TB Aura.

        • interesting. MIne also is the 4tb. I wonder if we differed in any way. First thing I did was re-install and erase the original SSD (using disk utility within internet recovery) and then do an internet recovery install. Then same again with the Aura SSD. I was surprised how the internet recovery was not too slow.
          After that it was plain sailing.

  • Although I don’t appreciate the time it has taken to not get an update to this issue I did do the workaround listed by other users and it worked flawlessly. Took 2 hours from start to finish but shouldn’t have to come to this.

  • Same problem here. OWC Aura SSD 500GB
    MacBook Air (13-inch, Mid 2013) running 10.12.6 cannot get past the firmware error when trying to upgrade to High Sierra.
    Any news on a fix?

    • I don’t have time to deal with workarounds that might or might not work. I’ll stick with Sierra until there is a resolution. My problem is the lack of transparency. C’mon OWC, give us a real update. Whose problem is this to fix, yours or Apple’s? Where are you in the process of fixing it? What is an estimated date you will have this resolved? Is there any possibility it can’t be fixed? Please be responsible and give us some real information. Thanks!

    • I gave up waiting for a fix. Even contacted support, and have not heard back.

      Using original SDD method worked for me.

      I have Air, 11″, model 6,1 (late 13 or early 14). I put the original SSD in, did an internet recovery, and installed high sierra. Took original SSD out and put OWC Aura 500GB in, and updated to high sierra and it worked without any trouble. Did a backup before just to be careful.

  • The Work Around Process, worked great for me.
    OWC Aura 4TB installled. re-install apple 1TB,
    cmd+R, ran Disk utility (Erase), installed High Sierra.
    Shutdown, re-install OWC Aura 4TB, cmd+R, ran Disk utility Re-install OS High Sierra, when it restarted, it was still running Sierra, went to app store open/loaded High Sierra and ran install again, that was it. Did not need to rebuild from Time Machine, everything was there and working great, just like it was, running High sierra (10.13.1). Man that is a load -off me.

  • It’s working now. If you try to install it will launch a firmware update. Once you do that… it allowed me to finally install High Sierra on my tower Aura SSD drive.

    • Aura SSD drive can install High Sierra, but the file system is still HFS + and can not be converted to APFS, which is the true value of Sierra’s move to High Sierra

  • I have a 2013 Late Mac Pro (6 Core) with OWC Aura 4TB installled.

    I got tired of waiting for an official fix. So I just went with the confirmed workaround: swapping OWC Aura SSD with the origial Apple SSD back and forth.

    I can also confirm the workaround REALLY works. I had misgivings since so many complained about their Mac Pro getting bricked and all.

    Yeah, the nightmare became reality when my Mac Pro seemd to have gone nuts with its fan shrieking.

    But I realized that I forgot to put back those power screws (not sure what they call them, those screws that connect Aura’s power cables to Mac Pro’s board.) Those are easily forgotten if you hurry. When I put them back on, everything went ok. It was logical: it should just work since it’s like not having installed the OWC SSD in the first place. No boot with shrieking fan? Check your screws.

    Well, if you have sold your original Apple SSD, you might be out of luck.

    But if you do have the Apple SSD, at least you have a choice: wait for an offical fix that might never come or just invest a couple of hourse of elbow grease.

    • One thing you should also consider is if you have any bootable external drives or RAIDs, if you have them with any OSX version other than High Sierra on those drives, those external drives will not be able to read files on your High Sierra drives. For this reason, I opted to keep El Capitan for now. Has anyone experience with installing High Sierra on HDD drives?

  • I have a MacBook Pro 17″ (Late 2011) – MacBookPro8,3. I installed an OWC Mercury Electra 3G MAX SSD 1TB hard drive back in 2014. I tried the macOS High Sierra update several times by myself and with the assistance of several Apple Specialists over chat and on the phone. Eventually that had to do call me back so that they can have some of their engineers look into my particular issue. One issue was the EFI firmware not updating, or something like that. When I would boot into CMD+R or CMD+OPT+R, it would want to install OS X Lion. Eventually I was able to update this portion of the EFI and now when I boot to Recovery I can install macOS Sierra, however, I attempted an upgrade again to macOS High Sierra and it gave me the same firmware verification error. The latest Apple Specialist has set up an appointment to a local Apple Store so they can try something out. Total number of hours spent trying to get macOS High Sierra… 10 hours. Good luck to the rest of you trying to figure this out.

    • Today, my Mac Pro (2013) Aura SSD 2TB is the perfect solution for installing macOS 10.13.2 High Sierra. No need to replace the original APPLE SSD, make the boot disk, right in the Aura 2TB SSD, direct disk formatted APFS format, and then a new installation, everything is going well. The problem seems perfect! At least on my Mac Pro this is the case.

  • I have a MacBook Air 13 inch mid 2012 with a 1 TB Aura 6G SSD installed. Reading the comments below, I was very reluctant to try the High Sierra upgrade.
    Long story short, it went smoothly for me.
    I used the 10.13.1 (17b48) build (about the 3rd version of High Sierra).
    My original disk was in the Envoy, and I first did a clean install to that as a trial. That worked OK, as did installing on top of the existing Sierra that was on my Aura.

  • For those who are new here: OWC emailed me a few days ago with a workaround…
    Put original SSD in system, install HS. Put Aura SSD in and reinstall. complicated but they say it will work to upgrade the system Firmware.

    **I HAVE NOT TRIED THIS** I bought a new computer instead (due to other issues).

    They also said they would update this post. I see that hasn’t happened.

    • This solution, although a pain to do, I can confirm worked in my case. Luckily I had the original Apple SSD in an OWC housing.

      • Since replacing the primary drive would entail for most people having to do a full Time Machine restore, how do you do this if Time Machine has the old OS on it?

        • I had a SuperDuper bootable backup on my original Apple drive in the OWC housing. Removed that drive from housing, reinstalled in to my MacBook Air, and did High Sierra update. Removed that drive, re-installed OWC in Air, then did High Sierra Update again. Took a few hours, but does work.

  • I have a 2013 Mac Pro and purchased the 4TB SSD from OWC as well as 128GB Memory. I contacted them today and was given a fix that worked for me. I was told to put my original SSD back in the mac pro, upgrade to High Sierra and put the OWC back and upgrade to high sierra. It worked. I am happy that the OWC SSD now shows as internal and i am also happy to be on High Sierra. What i don’t understand is why the Drive was not automatically upgraded to the new File System. I did an in place upgrade and not a clean install. I might try it this weekend .-

      • it appears that Macsales offers the option to rent a 256GB SSD from them to do it. I am not sure how that goes and how they would take money from a client to fix something they should be fixing. Maybe whatever money you pay is in case you don’t return the drive. It’s worth checking with them to verify.

        • I have the Envoy SSD but with no instructions. Tried installing Mojave on this external SSD OWC sent me and get the same errors and doesn’t install.

    • This worked for me. It was pretty straightforward, just a little time consuming swapping old drive in and out. The Aura SSD does retain the old file structure.

      • Joel, will you try to reformat so you can use the new file structure or will you remain with the old file structure. I think i am about to try .. i will let you know if that worked.

    • Update on High Sierra Clean install on Mac pro after install on 11/15. The install on 11/15 retained the old File System. I did a clean install on 11/18 , reformatted the Drive to APFS and it worked …

  • I am one of the affected customers, and I never received any communication from you about the problem. I only found out about it after spending several fruitless hours trying to determine why I could not install High Sierra. Please try to beef up you communications to affected customers!

  • I was looking to upgrade my Mac Pro 2013 running El Capitan with one of these, although I’m seriously not considering it now, I’m not sure how long Apple will continue to support EC with security updates.

    This is a significant worry.

    Seems somebody has been looking at this since Sept and no updates forthcoming in the last couple of months. This is a big chunk of cash to part with for a very limited lifespan.

  • I contacted you folks back when High Sierra came out back in September and your response was to watch this blog. No change here. MacBookAir6,2 (13-inch, Mid 2013) with installed 1TB Aura SSD. Really do need a solution path quickly to install/upgrade to High Sierra.

  • I Bought a OWC 240GB SSD for my MacBook Air Mid 2012, Every time I try to Install the High Sierra with the Apple installer Kit, I received this message: com.apple.osinstallersetup.LinkFileDownload erreur 3
    What can I do about this.

  • me too Model Identifier: MacPro6,1 Aura 4tb fails High Sierra update. Mostly just doesn’t install, one time spotted the “firmware error” message. No email received here. SO9711366

  • OWC. I have the OWC Aura SSD 4TB and you didn’t send me any emails. I get the blinking folder with a question mark and then it says there is a firmware problem. When are you going to fix this?

  • I believe I am one of those affected by the aura SSD upgrade kit (order P4890513) as I have not been able to upgrade to high Sierra, it will give me a unbeatable disk logo followed when rebooted a message about the firmware not being able to be verified and to restart, then it restarts back into Sierra. Is there recovery date as of yet? So far this has not caused any problems but I am worried that I use fairly high end software that may require High Sierra in the near future. Thanks for any help you can provide.

  • I have an OWC Aura ITB Ram upgrade for Mac Pro (Late 2013) and am unable to upgrade to High Sierra – Midway through installation, I get the flashing folder with a question-mark. I’ve tried the installation several times and the same problem arises. I guess this is related to the new AFS file system. Please help

  • I have the 2013 Mac Pro with aura update
    I was going to use it for an esx server but the esx install couldn’t find the disk, now apple high Sierra can’t find the disk either resulting in the same firmware update error as others have seen.
    whilst it is certainly not an acceptable get out for OWC has anyone tried attaching the old apple ssd with the external hard case that comes with the kit and updating the aura as a secondary drive?
    I definitely think that some kind of reduction is in order if it needs a new own product to get round the error

  • Does a failed High Sierra installation attempt make it impossible to boot from the prior Sierra installation or damage anything?

    My 2015 MacBook Pro retina is not on the list of affected machines. I have a 1TB Aura in this machine.

    I’m willing to try installing High Sierra so long as it’s not going to brick the Aura or my MacBook Pro. I have a bootable external clone and two Time Machine backups I can restore from if needed. Any recommendations?

      • Ouch! Thanks for your reply, that experiment is off my to-do list.

        This is a real problem for many Aura customers. I wish OWC would provide regular updates on the issue.

  • Getting so sick of Apple’s annual update of Mac OS X and iOS. Every single year, users have to worry about whether their machines will “just work” or not after the upgrade. It’s even worse for those of us who dare to use third party hardware.

    Sure, one can hold off on upgrading annually, but after just three years, more and more applications and programs (like Chrome, Dropbox, Python, etc) no longer work with older systems. At the same time, iTunes no longer connect with the latest iDevices. So one is forced to upgrade sooner or later.

    Apple, the master of planned obsolescence. I never understood why so many fanboys have become brainwashed into being excited by each and every new release of Mac OS which add functionality that most of us (middle aged adults) don’t care about and probably would never even use.

    • … On here, we are not talking about stages of life, we are talking about how our purchases do not work. I bought a OWC product because they are well known in relation to Apple Software. If because a new update of Apple, the products do not work, it is okay: it is reasonable. However, the “reasonable” is to refund the money to your clients or otherwise, provide them an original producto with which they are able to work with. Need I explain myself better or clearly? Please, we look forward to reading about that solution NOW!

      • Hey OWC, so you sent me an email on 9/25/17 alerting me to this problem with no updates since. And you’re not participating in this discussion and providing any info here, although the comments are moderated and you are obviously reading all of them. Your reputation will take a hit if you don’t provide more communication and transparency in dealing with this issue. Where are you at in the process of resolving this issue? What will you do if it can’t be resolved? Aura owners want to know. Thanks!

  • We have 6 machines (late 2013 MacPro) all running Aura 4TB SSD upgrades. They fail the upgrade with a “firmware” error. Is there an estimated timeline for a fix?

    • I have a 2013 Mac Pro and purchased the 4TB SSD from OWC as well as 128GB Memory. I contacted them today and was given a fix that worked for me.

  • I have a late 2013 MacPro with a 2TB OWC Aura SSD. Please let me know what to expect with High Sierra and when it will be safe to upgrade.

  • Hi everbody! Could somebody help me, please? Like for the moment we have no solution, in my case, I am a MacPro Late 2013 user who sold the original SSD. Do you know some web page which sells original SSD by Apple? …This way… at least, I am able to install macOS High sierra

    Thanks in advance

  • I just tried the 10.31.1 HS as a clean USB install on my Mac Pro 2013 with Aura SSD and get the firmware error part way through installation. Reformatted as OSX-Journaled and it failed (is this the same as HFS+? I don’t get that option in the disk utility drop down when re-partitioning), reformatted as MSDOS and it won’t allow an install on that file system. SSD was £1000 and change and it’s brand new, wish I’d read this first… Rolling back to the installation OS from 2013 and hoping that at least works…

  • One of the big frustrations about this whole thing is that the introduced a new product line offering rebates to upgrade but many of us, like myself, are not eligible. I purchased my drive in June of 2015. It’s still under warranty yet not eligible to upgrade because they will not accept drives older than 2016. They are still advertising that the Aura works with High Sierra on their website when it doesn’t and offer no updates when it will be available. The lack of support for current and loyal customers is disheartening.

    • I agree. The lack of transparency is frustrating. If there were weekly updates of where things stood with this process, I would have more confidence that it was actually being worked on.

      I support about 25 Macs as part of my job and make recommendations to many other users. If this is not resolved in a satisfactory way for current customers, I am done recommending OWC products for anything.

  • Just for the record: if I try to install the last version (10.13.1) in my MacPro Late2013 with HFS+ format and AURA SSD 2TB…will it work? Please, note that I have sold my original SSD by Apple.

    Could somebody help me? Thanks in advance

  • What was it Donald Perreault? An opinion or an OWC advertisement? I spent more than €1300 to get a AURA 2TB, so, where is my money?

  • I spent $2000 on my 4TB Aura for my Mac Pro, almost as much as I spent on the Mac Pro itself. I want an update on the process to fix this and when to expect a resolution. If it can’t be resolved, I want to be able to upgrade for a minimal fee. C’mon OWC, be more responsive to your existing customers please.

    • I concur. I also have the Aura 4 TB drive. It’s only a year old. I feel like OWC should send me a replacement 4 TB drive that works with the latest version of the OS they claim to support.

      Here is my chat transcript from customer support:
      Chas B (10/13/2017, 2:50:13 PM): Byron, thank you for contacting OWC Support. I am happy to help! One moment please while I review the information you’ve provided.
      Chas B (10/13/2017, 2:55:06 PM): Hello Byron, I am happy to help.
      Chas B (10/13/2017, 2:55:22 PM): I am sorry if you have had any issue with that install of the OS and the machines that are affected.
      Me (10/13/2017, 2:55:32 PM): Thank you.

  • I admit I am very anal and when things aren’t working properly or the way I want them to on my Mac Pro (2013), I do whatever is possible to resolve the problem. My solution turned out to be, purchase the new Aura Pro X 480. I then traded in my Aura 1TB for a rebate of $320. I lose half a terabyte storage and the Aura Pro X ends up costing me about $120 with the return.

    This works for me because I wasn’t using but 30% of my Aura 1TB anyway. I off load most of my data onto a 16TB OWC 4 Disk Raid 0. Therefore, the loss in internal storage is not a problem for me.This may not be a practical solution for most but it worked for me.

    I am extremely happy with the new Aura Pro X. It is much snappier than the old Aura on my Mac Pro (2013). Not sure if the speed difference is the HS, APFS or the new Aura Pro X, most likely a combination of all.

    Needless to say I am not pleased with how OWC handled the whole High Sierra Aura situation. I’ve been a long time customer and have spent thousands at Macsales and this is the first problem I ever had. I have had two SSD drive failures that they replaced in warranty immediately. So I certainly can’t complain about their customer support. As a matter of fact they have top notch customer support and tech support. The representatives are always polite and helpful. OWC is the premier engineering company of Apple Hardware and for that reason I will continue purchasing from them in the future.

  • How much longer we will have to wait?

    It has been a month already, we need some updates instead of coming soon.

  • I’m not sure if my first post went through or not but here goes.

    Hi Ryan could you be more specific and say if you were able to install High Sierra 10.13.1 on your OWC Aura SSD media?


      • Hi Ryan,

        Many thanks for your quick follow up. Before I take the plunge, did you have to do anything specific? For example my 1TB OWC drive is Mac OS Extended (Journaled) which is HFS+ with journaling. Did High Sierra 10.3.1 ask to reformat your drive to HFS+, etc? You didn’t swap out drives or anything of the sort? I apologise for the many questions in advance, but it appears that Apple are the ones who allowed the “Rotational Drives” to be used in their 10.3.1 update and not OWC.Thank you.

    • Yes! Installed it last night on a MacBook Pro (13″ late 2011) with a boot HD Samsung EVO SSD. No problem at all. Only concern was when the fan was speeding and it eat about 7 Gb of SSD storage (after the upgrade). But now it’s quiet and working as expected.

    • There is no mention of dealing with 3rd part SSD. Seems like the big change: “Adds support for 70 new emoji including food types, animals, mythical creatures, clothing options, more expressive smiley faces, gender-neutral characters and more:

    • I tried the latest version and still can’t get past the firmware error. I’ve tried to get help numerous times on this and I’ve also asked about the availability of a trade-up to the one that actually WILL work with 10.13.x I was told that a solution would be coming soon. That was a few weeks ago

  • Hello

    I recently did everything I could to update my Mac Pro (Late 2013) to MacOS High Sierra. After wasting nearly a whole day, I gave up.

    Having just come across this post after clicking a link in an email you sent me, it sounds as if I have found the reason!

    The is what I see in System Information:

    Device Name: OWC Aura SSD
    Media Name: OWC Aura SSD Media
    Medium Type: Rotational
    Protocol: PCI
    Internal: No
    Partition Map Type: GPT (GUID Partition Table)

    Please let me know when you have a fix. Thank you!

    • No solution for more than a month. However, I am afraid that you can get your “own” solution: buy the Aura SSD X PRO :) :) :) :) :) :) :) :) :) :) :) :) :) :) :)

      Same situation than you. My device: MacPro Late 2013 Aura SSD 2TB

  • The MacSales.com web site (as of 10/30/17) lists the original Aura SSD for the 2013 Mac Pro as being compatible with MacOS High Sierra. Does that mean that they now have a “fix” for this problem?

  • From the MacSales’ site:
    Innovative, Dependable, and Made for Mac… custom engineered for your Mac Pro
    … industry leading suite of controller technologies to deliver longevity and dependable performance …
    Back by OWC’s 3-Year Warranty.

    … reliable performance long into the future
    … exceptional warranty

  • I reported a High Sierra glitch with my OWC Excelsior SSD wherein it no longer reports free & used space accurately. To date OWC is ignoring it.

  • This impacts the MacBook Air (late 2010) with Aura SSD installed as well. Any update on a fix? I have the Aura SSD installed on the Air and a MacPro. Ended up buying a new MacBook Pro because I thought the Air installation had trashed the machine.

  • Mercury Accelsior E2 PCI SSD drives also appear to be affected by this issue. These also show as Medium Type “Rotational” in the System Report as opposed to SSD. The High Sierra install would crash at the beginning and send me back to my current OS. I have a Mac Pro 5,1.

    It is a pretty tedious workaround but by inserting an old SSD into my Mac, taking a full Time Machine backup and restoring it to this SSD, booting into it, upgrading to High Sierra, doing another Time Machine backup and finally restoring the new High Sierra backup to my OWC SSD I was able to complete the upgrade.

      • True, I was trying to stay positive. :)

        I think my bigger concern is at what point did OWC realize this was an issue, and was there any attempt to notify customers of the issue? I spent multiple hours trying to upgrade, and only happened upon this page in looking for answers. I would hope that prior to the official release, they had already identified this issue and communicated this to Apple.

  • Hi , what about question mark on reboot error – have solution soon – too ? When the OWC Aura SSD is installed in a mid-2013 MacBook Air 13″ (MacBookAir6,2), the computer may intermittently boot to a flashing question mark. Restarting the computer or resetting the SMC will allow the computer to boot normally. We are working to resolve this issue.

    • Hi, Donald. We are still working with Apple on a fix for the issue affecting third-party drives. We do expect a resolution to come soon for the Aura models mentioned in this article.

  • Hi there! I am Rubén from Spain. I am very disappointed too. I have gotten the same problem: Mac Pro Late 2013 + Upgrated with OWC Aura SSD Mac Pro 2.0TB Internal Solid State Drive.

    MacOS Sierra was deleted by Apple frome the AppleStore, therefore, should I / we suppose that the only option available righ now for me/us, is to update to OSX El Capitán 10.11? Right?

  • Hi. I have purchased an upgrade from you for my 11″. I haven’t received any kind of communication concerning the high sierra install issues. Your assistance is appreciated

      • Hi Jarrod,

        I know many of us would like it soon since we have Aura drives and have been waiting. Also, I wonder when I go to Aura drives why there isn’t any mention that currently it is not compatible with HS? I would think potential customers would like that bit of information.

  • My 1TB Aura is working on my Late 2013 MBP running High Sierra, but if I don’t keep waking it from sleep after a few minutes, it requires me to do a hard reset to boot back up.

    Is there a driver update or something coming soon?

    • We are very sorry for the troubles that you have been seeing. We are working with Apple closely and expect a resolution soon!

      • Add me to the list of Aura 1TB MacPro (Late 2013) users who cannot upgrade to High Sierra – blinking empty folder.

  • I have a 500GB Apple internal SSD drive in my iMac and 4 400GB Micron_P400 external SSD drives in an OWC Thunderbay 4/mini enclosure. Can I convert all of these drives to the new file format, if and when I move up to OSX 10.13? (I am now on OSX 10.12.6.)
