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 What a difference July 4, 2020 I should have upgraded my storage long ago. Never having taken my late 2013 iMac apart, I hesitated to try this. I'm so glad I did! The installation video was clear and detailed and the tools provided enabled me to easily remove the display and install the new SSD. The instal took about 45 minutes. And wow what a difference!!! Opening programs - a snap. Rebooting, faster than ever. I upgraded my RAM with OWC RAM to 32 MB and now my iMac behaves like a new machine. I would totally recommend these upgrades and price was right!

Rating: 5/5 Foolproof April 15, 2020 I am no computer technician, but I am pretty handy, so I was comfortable attempting this installation on my own. I probably could have found a cheaper drive, but this kit included everything needed: tools, adhesive strips (clearly marked where each piece goes), solid state drive, adapter. Everything needed to take your computer apart, replace the drive, and put it all back together. Everything worked perfectly! Definitely use the online instructional video. I recommend watching it several times before starting the installation. I wouldn't say it was easy - it was pretty involved, taking your computer apart - but if you're reasonably handy and can follow detailed, clear instructions, this is really not that hard. I also recommend having some canned air on hand, especially for the speaker holes at the bottom. Lots of lint and dust. SSD is great - startup is much faster. I can't speak to longevity, obviously, but I'm confident. Nothing negative to say - I'm impressed.

Rating: 5/5 I think I could cure a cloudy day.... December 5, 2019 I decided to work on my 2012 iMac that had both a bad fusion drive (bad SSD and intermittent HD). I was booting from an external SSD, but the HD starting up from time to time was throwing errors that caused the machine to have hiccups.

My ability to do things like lining up a screen on adhesive tape is pretty limited (I'm a geek and anything remotely neat is beyond my ability). So I got it all done with the screen only slightly askew (about 1/16" which will drive my OCD crazy forever). However, now everything works dandy.

Patience is definitely called for here, and the screen power cable is a "expletive deleted" to get off, and not much more fun to reconnect. But if it can be done by the most 10 thumbed amongst us, it can be done by almost anybody.

The instructions are top notch, and time from start to finish was about 2.5 hours with lots of time dedicated to taking deep breaths and thinking it through. Highly recommended.

Rating: 4/5 All in all, not too hard December 5, 2019 Fairly simple if you don't include the adhesive strips. Take your time, clean all the old adhesive off, supposed to come off in nice strips, but well....when does anything get that easy. The screen is the hardest part. Use a head light so you can see inside to disconnect the screen. Be careful when you do the first lift, only open it 4 inches or so. If you are handy and careful, you can do this.

Rating: 5/5 Very impressed with the ease of installation September 5, 2019 Installation in my 2015 iMac 5K took about 40 minutes total. I took a few breaks between my work, but it was very easy to do the physical replacement of the HDD.

I played the installation video on my old MacBook Air–pausing quite frequently–but I was never lost on what to do. I was very impressed that the kit contained all of the components needed to perform an installation and restore the computer back to its configuration.

The downside to my installation was the length of time it took me to restore. I used Time Machine to backup on my LaCie 2-disk RAID, but attempting to restore with the entire system was slow and it failed twice. So, I simply re-installed the OS first then restored from Time Machine, which went well. (By the way, it's probably time to upgrade the HDDs in the LaCie to SSDs. I know where I can find a few at a great price.)

I am happy that a temperature sensor board was included. 4 years ago I replaced my HDD with a fast HDD in my 2010 iMac. I honestly stopped using that beautiful iMac because there wasn't a good solution to manage the fan. It looks like this problem is solved and I'll upgrade that HDD to an SSD now.

A truly complete solution.

Rating: 3/5 Okay, but could be better June 8, 2019 I received the kit and started going through the process of removing the screen so I could replace the HDD with an SSD. Everything went well until I tried to use the suction cups to lift the screen off. One of them was defective. I tried several tricks to make it work, but it would not. It is hard, but not impossible, to remove the screen with one. Two would have been better. The second issue is with the new display tape pieces. They are in a box all folded up. I would suggest laying them out straight on a flat surface and laying books or other flat objects on them for several minutes so they straighten out. The ones that go on the iMac frame are fairly easy to install. The ones that go on the bottom of the screen are not. I couldn't get the backing off of them with just my fingers. I had to get an exacto knife to get between the tape and the peel-off backing. That took some effort. Otherwise, the process works well.

Rating: 5/5 Everything you need! May 30, 2019 I was impressed with this kit... it comes with a nifty tool that makes the seemingly daunting task of removing your iMac screen very easy and safe. The cutting depth of the tool prevents any possible damage and the thin, strong circular blade makes short work of the adhesive holding your screen to the iMac body. Clearly labeled replacement adhesive strips. Too early to tell about the reliability of the 2TB SSD, but I've purchased SSD hard drives from OWC for a couple of older laptops, and they are still working very well. I think the hardest part of this install was gently unplugging the screen cables.

The purchase was accomplished with all questions answered up front, the free shipping arrived a day earlier than expected, and the product and complete install kit are simply terrific. All the tools and everything needed for the job were included, and all worked flawlessly. The install videos are first rate, and make the entire job quite easily accomplished with some attention to detail and some patience.

Rating: 4/5 Really good. Almost 5 stars. December 31, 2018 The fusion drive on my Late 2013 27" iMac failed. The SSD part was fine, but the mechanical drive was shot. I went ahead and split the drives, kept the SSD blade and installed this 2TB SSD, leaving them as separate drives. All in all, it worked out well. The replacement of the drive was really easy. Just follow OWC's video (and check out iFixit.com if you want). The display is much easier to take off than it appears, and after the it is pretty trivial. I will say, a second set of hands to remove and reinstall the monitor is nice to have.

I did have problems formatting the drive after it was installed (note: I used a display port to HDMI cable to my TV to check things out before sealing things up. The fan goes nuts at this point, but better than wasting the monitor adhesive tape.) Anyway, the drive formatted just fine in a Voyager SATA dock, but not once installed in the iMac. Various research (including a chat with Apple Support) indicated a possibly bad SATA cable. So I went that route and replaced the cable (not fun but doable, as the logic board has to be removed). That didn't fix anything, but while staring at my open iMac, I saw that the kit from OWC included a SATA to SATA adapter board, plus a SATA to SATA cable (with the thermal sensor cable). I figured that was a lot of connectors, so I removed the adapter board, and viola it worked. So if you have problems, that might be your solution. If not for that, I would have given 5 stars.

Rating: 5/5 WOW! So Much Faster! December 14, 2018 With my original hybrid drive failing, I ordered this DIY kit for my 2014 27" retina iMac and put off installing it until my computer was going so slow, it took over 10 minutes to boot. Opening an app took forever, too. To be honest, I held off installing it because, in spite of watching the install video about 6 times, I was still scared of cracking it open and diving in. I won't say that it was a breeze, but it was fairly straightforward. Opening the iMac was easier than I thought it would be. Taking out the old drive and putting in the SSD was easy, too. Reconnection the two cables to the screen was the hardest part because of my short, stubby fingers and 72-year-old eyes. I couldn't test boot because I couldn't use the old drive, so I sealed it back up. I had prepared a boot install drive and started her up. I breathed a sigh of relief when I heard the familiar startup chime and saw the Apple logo appear on the screen. After installing the OS and restoring from Time Machine, I was and am still astounded at the speed. And the quiet! To borrow from the Mazda commercial: Zoom, zoom. It's like having a new computer!

Rating: 5/5 Easy as can be! October 22, 2018 This worked like a charm. My late-2012 iMac hard drive failed after upgrading to MacOS Mojave. I considered buying a new iMac but I'm glad I saved $1000 by just replacing the hard drive. And, holy cow, the thing flies now with an SSD! Lightroom, iMovie, and other big apps that used to crawl are fun to use again. Startup lasts seconds instead of minutes now. The installation was medium complex, but they made it about as easy as they could as a DIY kit. The trickiest part was testing the hard drive before re-attaching the screen -- I was doing some acrobatics to hold on to everything. Watch the video before you order and again as you make the change and you'll be fine.

Rating: 5/5 Amazing Improvement! March 4, 2018 The new SSD works great and has massively improved the performance of my iMac...it was easy to install by following MacSales.com's YouTube video with their installation kit. I couldn't be happier!

Rating: 5/5 Good product and great service February 20, 2018 We have installed 2 of theses repair kits in iMacs in one of our science labs. The repair has gone smoothly and works perfectly. Compared to our local Apple repair we can do this ourselves on a 2 for 1 cost basis and save transportation time and expense as the repair shop is out of town. The added bonus is a quick turnaround on our order. Parts arrived in two days and repair made same day as arrival.
