Rating: 5/5 FANTASTIC!!!! January 1, 2020 incredible upgrade to my iMac late 2013 (model 14,1)! I changed out 2 x 4GB with 2 x 8GB and change the 1TB HDD for a 2TB SSD.

1 - The installation video was incredibly well done and walked me through the process. The power board and the logic board were a bit tricky to remove (as the video indicates), but if you watch the video carefully, you can mimic what the tech does and get the boards out and back in without an issue.

2 - The tools and equipment provided in the "kit" are excellent and I'll be able to use them for future work on this iMac or others.

3 - The speed pickup is out of this world. I had though the iMac was somehow failing, but now realize it was just the volume of data on the disk, and the large OS X and other standard applications that were slowing it down. Won't even be thinking about a new machine any time soon.

4 - The small external drive case provided to use your old HDD as an external drive is great and I've got an adde 1TB backup drive now.

5 - Only trick is APFS and Mac OS. Installing Mojave on an external drive before doing the swap out proved a bit frustrating because even after formatting the external drive as Mac OS, when Mojave was installed on it, it changed the drive to APFS. I reformatted to Mac OS and tried again and got the same result. The result was that I could not rely on Time Machine to backup my files before the move and had to do things by hand. Luckily, the old internal drive had no issues and when i hooked up as an external drive, I was able to use Apple migration assistant to move the data from the old HDD to the new SSD.

Thanks so much for the super detailed instructions for both the hardware and disk set up/format/OS/data transition.

What a great experience. Mac Sales is awsome!

Rating: 5/5 Great Upgrade August 21, 2019 great kit! everything you need to do the upgrade..I also got a ssd from here and installed at the same time. I also replaced the thermal paste on cpu, I am glad I did it was really dried out. New life in the old iMac. Instructions video is great.

everything went fine until I was getting ready to hook the display back up to do a power on test. I was holding the display with one hand and turned to get a cloth off the other desk and the display dropped off the lip of the housing and cracked of course. So that will be my next project if I can find one that don't cost as much as the Mac is worth. but everything works and it is a small crack that you can't even see when the display is on.

Rating: 5/5 Easy DIY Upgrade April 2, 2018 I replaced my original iMAC hard drive with a new sold state drive and added more memory going from 8 GB to 16 GB. Oh my gosh what a difference that made in speed. I am looking forward to more leisure time this summer since I won't be waiting around for seconds leading to minutes leading to hours for my screen to refresh. The OWC step by step videos made installation a breeze.

Rating: 5/5 Exceeded all my expectations March 3, 2018 Everything worked flawlessly - the video, tools and hardware were all very impressive and made a challenging job a breeze. Couldn't be happier.

One suggestion ... I would recommend that the screen not be reapplied with the supplied 2-sided tape until all operations are verified. I attached the screen with blue painters tape for my dry run ... good thing because I had forgot to attach the video cable.

Rating: 5/5 Great kit and easy way to extend life of iMac January 2, 2018 Thank you for a great kit. My late 2013 iMac is now flying through everything that had previously made teh system crawl. The video showing each step was key for me. The video says the level of repair is expert but I guess that is due to the steps involved. I upgraded my hard drive to SSD and I couldn't be happier. Just make sure you have excellent backups before tearing into your Mac just in case something goes wrong. Take your time and watch each step over and over if something is tricky when you are doing the tear down. It just takes some time and patience. I could do this in half the time if I had to do one again. Thanks for a great kit.

Rating: 5/5 Not as tough as it looks June 20, 2017 This all went pretty well. It took me a couple of hours I guess. Longer because after I had the new RAM in I reset the display temporarily to make sure everything was working properly. Getting display off is not bad; just keep going around and don't pry it. Once in side just follow steps and keep components and their screws organized. The cable between the power board and mother board I found to be tough to remove. My fingers struggled with that. Resetting the display must be done carefully so that edges line up correctly. No wiggle room there. All in all I'm very happy with results. Glad it's over though. Thanks.

Rating: 5/5 Easier than I thought March 13, 2017 Don't get me wrong, tearing down a late 2012 model iMac to swap out bad memory is not a task I would encourage anyone to undertake. Apple did NOT make this a user friendly process, and if you're not careful, you can crack the display glass or damage the system boards.

Having said that, the tools MacSales.com provides in the bundle made it easier, and the "how to video" they have goes through the process step by step, which makes it a little less daunting overall. Hindsight is 20/20, so use me as a gauge; if you're going to do this, you may want to seriously consider adding a Solid State Drive to the bundle. You're going to have to remove the drive to get to the memory anyway, so it's the perfect time to upgrade this as well. I'm kicking myself for not doing it.

Rating: 5/5 Sure Sped Up My System! December 14, 2016 This was an undertaking as the memory on my iMac is located on the bottom of the motherboard- I used my iPad with the instructional movie from Mac Sales and it was not hard to do- One should be familiar with working on computers tho! I got her done and it worked perfectly!! I advise having their tool kit ! My iMac was a low priced unit so there was not a door for the memory slots. The movie helped greatly!!!

Rating: 5/5 Amazing speed. December 2, 2016 I already had 8GB ram on my iMac 21.5 late 2013, but felt needed more - seeing the spinning beach ball rather frequently was quite annoying. Got the 16GB (x2 8GB) from OWC and it's just amazing the difference I see in my iMac now. I have to say, replacing the boards and reaching the undersurface of the logic board is a challenge and had it not been for the video clip which can be streamed from the OWC site, and some experience I've had in similar work, I would not have been able to do it at all, and would have easily damaged a part or two. I also replaced the HDD with SSD on my iMac, and now I have a really different computer. No noisy fan either. Fast, quiet, and no spinning beach ball. Very happy with the product, the service, and the end results :).

Rating: 5/5 simply amazing November 18, 2016 yes the process is technical and takes about 30 min. but as long as you go slow listen to the video its completely achievable. the memory upgrade was exactly what my IMAC needed. I was considering selling it until i did this. The only part that i thought the video was lacking was when you install the screen you should just go straight down with it. if you angle it in at the base like they state it leaves a small gap between the screen and the frame. nothing to big but it is noticeable. this is nothing that i would mark the product down on for.

The fact that you can get the tools, consumables, and memory cheaper than just the memory was the part that made it so great of a deal. If you have patience and some skill's you need to freshen up your IMAC with this kit.

Rating: 5/5 Made replacing RAM do-able November 14, 2016 This do-it-yourself package saved me quite a bit on replacing and upgrading my RAM. The kit came with everything I needed, and the tool set will come in handy elsewhere. The instruction video was good, and my wife and I were able to get the job done in 30 minutes or so. Don't know what Apple was thinking making the modules so hard to get at, but this kit makes it do-able for anyone.

Rating: 5/5 Great upgrade!!! September 29, 2016 While the process to actually install the memory is not as easy as one would want, that's a problem with apple's design department and not with this kit.

The instructions to perform the upgrade are very clear and if you follow patiently the video provided you will be done with it in less than 30 minutes.

I was a bit worried that one (or both) of the memory sticks would be DOA and the only way to check that would be to actually install it and then open the mac back up to remove them if something failed but now I will learn to trust the OWC sticker that says "lab tested" because everything went well on the first try.
