Please note, that before attempting to perform this installation, it is recommended you watch the associated instructional video in its entirety to determine your ability to perform this complex procedure. OWC assumes no responsibility for damage that may occur during the install.

Release Candidate (RC) firmware set

There are two kinds of firmware for SSDs Mass Production (MP) and Release Candidate (RC). Prior to an MP firmware release, there are beta firmware releases and an RC firmware release. Often, the RC is the same as the MP release, however there can be small changes and bug fixes made between the two. OWC has evaluated the RC for the 6Gb/s SandForce 2281 Processor and found it to be stable with no issues reported during our testing. However, as with any evolutionary product, issues may surface as different usages and configurations are employed and it is important to understand that there will be further updates and revisions.

Since no firmware update is currently offered for the OWC Mercury EXTREME Pro 6G SSD, no update page exists. To see the typical steps involved with a self performed field firmware update, please visit our 3Gb/s product update page at: http://eshop.macsales.com/Customized_Pages/Framework.cfm?page=sf_firmware.html

It is important to note that the current firmware update tool requires the use of Windows XP/Vista/7. OWC is currently working on a Mac OS based update tool, but we do not have an exact availability date.

Rating: 5/5 Good Choice August 25, 2020 My 2011 Mac's hard drive died and looking at the choice between another $1500 and this, it was an easy choice. Almost everything I needed was in the box. The instruction that came with it and the video made it relatively painless to install my new drive. I found a pair of hemostats helped with the screws especially with the magnets fighting for control. Taking my time and following the video was the best choice. There were a couple times I had issues - 1 connector was difficult (smaller hands would have helped) and i did take the wrong screw out but it became obvious quickly. Overall, the project is not difficult. Once the drive was installed, it was a simple matter to get everything reinstalled. It would have been helpful if the instructions included how to get the os and the steps required, but that is easy enough to find on Apple's support site. Now that my new drive is in, it's obvious that this was a great choice. My Mac is faster than when it was new and apps start much more quickly than before. This has definitely given me a few more years before I need to upgrade.

Rating: 5/5 The rebirth of your mac. May 7, 2020 Wow, I just finished installing this upgrade, and what a rejuvenation ! A new mac for a fraction of the price. don't hesitate do it (with caution!) I would like to point out that the connectors are really small and require a lot of patience not to damage it. If you have "big fingers" it would be better to deal with a professional. It's a pity that the proposed videos only present the replacement of an original 3.5 HDD and not a replacement with only one ssd. In my case the connections of the "adaptadrive" were reversed (see photo) but fortunately there was enough room to put the wires and connectors (in the right gutter) and not hinder the re-installation of the screen. And finally, to clarify the mandatory use of the thermal sensor and to eliminate fan panic after restart, it may be necessary to reset your System Management Controller (SMC).(https://support.apple.com/en-us/HT201295) after completion. I strongly recommend this upgrade but underline the finesse necessary to complete this task.

The install video on the site was SPOT ON and left nothing for me "figure out". I am by no means a computer guy and to be honest I had already made plans to take to a shop and get it fixed after I tried the install but it went as easy as shown! If there was anything I would add would be to have a pair of NON-METAL tweezers... but thanks to the magnets for the screen, I never lost a screw!!! LOL

Thanks MacSales, awesome product!

Rating: 5/5 Brought my 2011 iMac back to life February 19, 2020 My 2011 iMac had gotten to the point that it was actually painful. There were times it took literally hours to reboot the machine or the reboot would hang. Best case would be 20 minutes for a reboot. Hard drive was not making noises but was getting 80-85% full. My choices were to attempt this upgrade or buy a new computer. Due to the age of the system and being topped out at High Sierra I opted for the Electra 6G. The tools sent with the upgrade kit were sufficient, although I would recommend a pair of tweezers to be included since the screws on the LCD are set deep and get caught in the magnets’ pull. Word of caution, the LCD connectors to the logic board are tiny. Much smaller than the video makes it appear, but otherwise the install went well…I finished the first time and sealed the system up and turned it on…no screen. I called and was told I had to go back in and reset the connectors again, and the second time it went without a hitch. The LCD data cable connector (the weird one) didn’t seat properly the first time. Did a clean install of the OS and this machine now rivals my 2017 Retina 4K iMac for speed…no exaggeration. Boot up is within seconds due to the SSD drive. Apps open quickly and many glitchy things that were happening on the old hard drive have stopped. I am more amazed than I imagined I would be. If you have a choice between junking a machine and have the confidence do the upgrade yourself, it is very worth it and I would recommend this course before buying a new system…$160 v. $2,500+…very worth it. This machine will probably go another 5+ years now.

Rating: 5/5 Blinding speed to mid 2011 iMac27 running High Sierra August 10, 2019 Recently I installed 16Gb of memory from MacSales and then thought what would a SSD replacement do. I installed the memory then the SSD and (data backup was from time machine) my boot times have now become literally seconds, switching between applications are the speed of mouse clicks.

I installed the SSD into a SATA to USB enclosure and using the installer on my running MAC installed a bootable copy of High Sierra onto the target SSD. Then I replaced the HDD in the MAC with the SSD using MacSales kit and recovered all data and applications using Time Machine on MyPassport to the SSD. The MAC now has a new lease on life

Rating: 5/5 Great Product for Upgrading HDD June 23, 2019 My 2011 iMac 27" was getting slower and slower every year. Bought this and easily upgraded the HDD to SSD and this is the first time I've ever opened my iMac.

Installed on Saturday, June 22nd, 2019.

The SSD didn't come formatted as Mac OS Journaled so I had to format. The restore from Time Machine took about five hours. No complaints.

I've been using the iMac for about a day so far and the speed closing and opening applications has increased a lot. It feels like a new iMac.

Rating: 5/5 Modernized my iMac! May 18, 2019 Machine: Mid-2011 21” iMac, model 12,1.

This machine has become my “audio/visual” workstation, mostly for Logic, Photoshop, and Final Cut. I figured an SSD would really future-proof things. I use outboard hard drives for all my data projects, so I just ordered the 500GB SSD kit.

The OWC video is pretty much spot-on, though BIG item to note: the DisplayPort cable (which connects your LED screen to the guts of the iMac) is incredibly delicate. In fact, my cable was plugged in so tightly to the motherboard that the cable was damaged when I finally removed it.

If you also damage your DisplayPort cable, fear not, just buy a replacement (I bought mine from Beets Tech for like $10). Remove the old cable from the LED panel. The key is to plug the DisplayPort cable into the motherboard FIRST, and then plug it into the LED panel, as your final connection when closing up the machine.

Also, be super careful with the LED screen and the glass. Do not let your fingers touch the LED! I laid out some clean drop cloths on my couch and gently propped the glass and LED panel up against the couch back, so nothing touched the exposed surfaces (picture the panels at a 60deg angle, to the right angle of the couch back and seat). Once I had everything installed, I used the included microfiber cloth to gently brush off the LED screen (dry cloth, not wet), and then used it also to brush down the inside face of the glass, before replacing the glass on machine.

Another note: I highly recommend you format the SSD before installing it! I plugged the SSD into a USB enclosure, then formatted it with Disk Utility (Journaled, one partition), installed OSX on it (simply open App Store, re-download your current OSX, and have it install on your SSD), and then used a Time Machine backup to flash my original hard drive onto the SSD. Then I tested the SSD by using it as the startup disk (while still in the USB enclosure). Once I was sure that the SSD was all set, only then did I open up the iMac and install it.

Overall, this is a fantastic kit. The heat sensor works great. If you’re having a raging fan after install, then double-check the LED heat sensor cable; it’s the cable right next to the fragile DisplayPort connection on the motherboard. I had to push this heat sensor cable pretty firmly into its receptacle, in order for a good connection.

Once you’re up and running, zap the PRAM a few times (command option PR on startup). I cannot describe how much of an improvement the SSD is! Lightning fast machine, feels super modern, and I can’t imagine ever buying another workstation for audio/visual production. Thanks OWC!

Rating: 5/5 Excellent, but careful on install May 18, 2019 If you take your time and are very careful, there's no problem with the install, but if you've never gone inside a computer before I'd recommend having a dealer do it. The space inside is very tight, the magnets tend to grab the screws and they sometimes fall into the housing, and some of the connectors are tiny so if you've got big hands it's not that easy. Also, the video DOES NOT show the install of an SSD drive which is a bit of a pain. After installing the 3.5" enclosure I found there was no room to insert the SATA cables and had to "reverse" the enclosure to get it to fit. It would help if the video actually showed the SSD drive in the enclosure being installed. Other than the above, everything worked perfectly.

Rating: 5/5 Excellent Product January 14, 2019 I purchased this after owning several other OWC SSD's. While the install is fairly involved, the formatting, restoring and subsequent use of the drive is easy. It sped up my iMac faster than it had ever been. I can't recommend this enough, but unless you are experienced with computer building or upgrading, you may consider having a professional do the physical upgrade, as the process is very involved. The video is excellent and covers everything to install, however. So if you're at least mechanically minded, then you'll be able to handle the install.

Rating: 5/5 Like a new computer! November 3, 2018 I finally took the leap to SSD when the OEM 1TB hard drive died. Good thing I had a recent Time Machine backup. The video of the install was very helpful. I followed it and only had a few hiccups. One major was the bracket adaptor for the SSD and the data cable. The instructions were a little weak on that one. I have had it for almost a year and I have to say the computer feels new again. I strongly recommend this if you have an iMac that still can do what you want it to but is slowing down.

Rating: 5/5 Speedy old iMac! June 25, 2018 I had the perfect moment to choose to replace my HD in my iMac. It failed. I had said I would either buy a new iMac or replace the failed HD with an SSD in hope of regaining some lost "snap" to my 2011 iMac. Boy, did I ever get it back. Boot times are incredibly fast, launch times are very fast, render and saves in photo and video work are vastly improved. The only think hard about the install has nothing to do with the new SSD and just to the care and tools needed to disassemble the iMac. I had already been inside a couple of times for other issues, and thus, this was relatively easy. Booted from a system backup, formatted the SSD, installed from recent Time Machine backup, and I was up and running in a few hours. And it's been sweet ever since. I'm very happy I made this choice!

If there were any words of advice that I could offer, it would be to definitely take your time putting the adhesive strips down.

Rating: 5/5 Defeated by Tiny Connector! I Gave Up on Installation March 1, 2018 I was all set to get the SSD in my iMac, and I had reviewed the video repeatedly and rehearsed and memorized each step. I successfully removed the glass and screen, but when I got to the vertical sync cable it just WOULD not snap out as it was supposed to. My natural tendency would have been to just pull hard, but this was the first time I'd gone inside my Mac, and I don't do this professionally, or even repeatedly. Yeah, and let's not forget about the torx screwdriver I dropped inside the iMac and had to retrieve with a magnetized screwdriver.

I stopped while I was ahead, closed the iMac, and took it to a local computer store. For 1 hour's labor plus tax, a total of $89.87, they installed the drive, which is working perfectly.

Remind me not to try this again!

The installation seemed really straightforward, but if you don't have experience working inside a narrow space with small, sensitive connections-- and HAM HANDS-- save yourself the trouble, buy the drive and pay for the installation.

Rating: 5/5 It Works February 12, 2018 I was a bit nervous taking apart my iMac fearing that I might break the glass or screen. But the directions were easy to follow and I successfully replaced my ailing hard drive with a new SSD.

Rating: 5/5 DIY Kit for 2011 iMac's SSD was successful January 31, 2018 The installation of the new SSD drive went pretty smoothly. Nonetheless I want to offer a few comments regarding this installation.

1. Pulling off the screen using using the handles provided was a little hard. It must be done in just the right way for the screen to come off. 2. Once screen is off it would be a good idea to blow off the dust before you working on removing the old drive. It just makes it easier to see. 3. Pulling off the various connectors was tricky. These connectors are small and in tight spots.

Rating: 5/5 Great product, easy installation. January 23, 2018 My iMac mid 2011 is now 5 X faster than with the original Hard Drive. Installation was somewhat easy, thanks to the video. Since the video was about changing the HDD, I had to contact OWC tech chat service to know where to stick the provided thermo sensor. Answer was friendly, quick and accurate. A picture of the installed SSD drive with thermo sensor would help on this subject. Sorry, I failed to take one myself and send it to OWC. Instructions on formatting the new SSD drive was also a great tool. I also contacted OWC tech chat service about TRIM since it was not active in my first System report. I was informed that the "Electra SSDs do not require TRIM at all, as they utilize over-provisioning technology". But enabling TRIM will not hurt anything but may not improve anything as well. Since I'm no fan of using the Terminal, (scared of doing permanent damage) I decided to activate TRIM with "Trim Enabler " and having the option easily reversible. Version 4 of this utility is compatible with Mac OS High Sierra. So far, the iMac is faster than ever. I often check the read and write speeds and get around 5 MB/s readings. Once again, 2 thumbs up OWC !
