Rating: 5/5 The memory works fine. November 20, 2018 Bought these for a Mid-2012 MBP to help speed things up a bit. As the day goes on it seems to help. It takes just as long to load things the first time as it did before, but that's macOS's fault. The memory is doing it's job.

Rating: 5/5 Added memory when changing hard drive November 19, 2018 When I switched to a solid state drive, I decided to double my memory while my MacBook was opened up. Easy installation and as usual OWC had easy to follow videos. The hardest part of the project was removing those tiny screws from tha back of the MacBook! I can’t really say if the increase in memory speeded things up since I switched to a solid state drive at the same time, but generally more memory is a good thing and the laptop is really flying now!

Rating: 5/5 Never crossed my mind November 11, 2018 It never crossed my mind that I could have 16GB of ram in my MacBook pro 9,2 until I saw it on the OWC site which i trust. I bought the 2x8GB Ram to replace my 2x4GB. Receive the package in good condition and installation was a breeze after watching the installation video.

This upgrade breathed a new life in the MacBook. It is definitely a more than welcomed upgrade.

Rating: 5/5 Easy to fit, works exactly as expected. November 5, 2018 The 16 GB memory was sent from OWC promptly but delivery within Australia was slow (expected). When it arrived, there was less than ten minutes from shutting down to restarting. As promised, my MacBook Pro recognised the full RAM and where the amount of RAM is paramount, my computer has sped up. Six years old and it has a new lease of life. The RAM is now just quietly doing its job!

Rating: 5/5 Fits perfectly - Improves Instantly October 31, 2018 OWC’s memory for my old MacBook Pro laptop had enabled me to avoid trading it in on a faster model. The memory loaded up instantly and functions perfectly right out of the box. OWS’s great “how to” videos made it a snap and I am now one happy Mac user because I can keep my current machine going a few years longer.

Rating: 5/5 So easy! October 30, 2018 I had visions of a real effort required to upgrade my MAC till I looked on the web site and saw that there was a simple pop out door. The package was delivered quickly and the change is immediate. The old girl was getting pretty slow and now it is like a new machine for a fraction of the cost. I'm not sure how long the processor will be able to take SW updates, but till then, it's all good.

Reviewer: DerSchweisserBildhauer
Rating: 5/5 Satisfies that need for speed October 26, 2018 Lightning fast performance now on this 2012 MacBook Pro-! Maxing out the RAM to 16 gb, along with an SSD makes it perform better than ever imagined; running design, CAD and then CAM programs with Parallels, still no lag whatsoever. OWC's service is prompt and (again) delivered ahead of time. (A nice unexpected bonus included in the package to commemorate the 30th Anniversary of OWC was a mini screwdriver pen and a gift card voucher for an online winery- very cool!)

Rating: 5/5 Fast wake from sleep and take your computer back from Facebook October 15, 2018 Facebook is a bad product for a lot of reasons. In this case, because of how much of the computer's resources it uses to display a web page. It is often driving the browser up past 3GB. On a machine with only 8GB of RAM, that makes the performance reduce in other areas. I was going to upgrade to 16GB, but opted for 32GB for my spouse's computer and was told that it made a big difference. An easy way to combat the resource hogging Facebook.

Rating: 5/5 Great Product and Great Service! September 10, 2018 I bought 16GB upgrade memory for my mid 2012 13 inch MacBook Pro. My computer was extremely slow, and very frustrating to use. After the easy self-install, my computer works better than new! The ordering process was easy, the product came within days, and the installation videos on the website were great! After my installation, my computer was only recognizing 8GB of memory, but after a call to tech support, I was walked through the easy fix! I couldn't be happier!

Rating: 5/5 Worked September 4, 2018 Mac never advertised that these would work until long after the laptop came out and new operating system software came through. I appreciate that these were also pre-tested and confirmed to work on the same model of Mac. It wasn’t guess work buying and hoping it works.
