Rating: 5/5 it's great April 17, 2018 2 grad students, each with an older 13" MacBook Pro (model 9,2) that came with 4GB RAM installed. Bought 2 sets of 8GB for them. They easily installed it, and they're both happier. Not as happy as if they'd been bought new laptops, but happy with the increase in speed. If they're good, I may get them each a hybrid disk drive, and that'll make those old laptops feel a lot faster.

Rating: 5/5 Fabulous! April 9, 2018 I am so glad I decided to upgrade my 2012 Macbook Pro from 8GB to the OWC 16 GB. It immediately gave my computer a boost, with breathing room for RAM memory. I have an app which shows me how much RAM is being used and it was topping out with the 8Gig and now with the 16 gig it is regularly showing over 50%, which means I did the right thing. This is a great company - I've also upgraded to the 1TB SSD, both the new hard drive and memory were easy to install myself with the tools which came with the SSD.

Reviewer: 12AX7 Location: Bakersfield, CA Age: 55-65 Experience Level: IT Professional Owned Product: over 6 months
Rating: 5/5 Good deal and works perfectly March 8, 2018 The order arrived more quickly than expected, positive #1. Took all of about 15 minutes to remove the existing RAM from my iMac and install the new modules from OWC, positive #2.

On startup, machine ran short test (maybe 15 seconds longer than normal boot), recognized the increase in RAM and started up with no problems. Checked system information, had 32GB of correct RAM listed for memory. Positive #3.

iMac felt quicker, noticeable but not huge difference as it had 16GB before, but multitasking and program startup both benefitted from the addition. I was able to re-use the prior installed RAM to upgrade an older Mac mini, so this was a win-win all around.

Thanks, OWC!

Rating: 5/5 Fantastic! Money well spent. March 7, 2018 The RAM was easily installed. There was an immediate improvement in my 2012ish MBP’s performance. It felt like I had a new machine. The performance improvement seen after the RAM update removed any doubt about my continuing my upgrade with the purchase of an SSD drive.

Rating: 5/5 Totally stoked with your service January 30, 2018 I recently purchased a memory upgrade for my iMac after being told by Apple that I could not do this myself and that they would need to keep my computer and do the installation. Not true! It actually took about five minutes to remove the plug, open the little door by that, insert the chips, plug it all back in and reboot. Now I have tons of memory!

Reviewer: MacJustMac Experience Level: IT Professional
Rating: 5/5 Excellent upgrade to keep an older MacBook Pro alive! January 26, 2018 Trying to keep my nephew's mid-2012 non-retina 13" MBP relevant for the remainder of his college years. Started with this component (SSD and Battery also part of the upgrade - separately reviewed). His MBP came with 2x2GB of RAM. Hardly sufficient for running Sierra plus other apps like MATLAB and old versions of Microsoft Office. This upgrade doubles the 8GB limit that Apple originally imposes on this model, so it's a huge win for the money. I've applied these "RAM Doublers" in other compatible models and they work as advertised. My nephew performed the upgrade himself under my remote guidance over FaceTime.
