Rating: 5/5 RAM is great! April 9, 2017 After many agonizing years of deciding on whether to update the RAM in my MBP I took the plunge and am glad I did. The RAM works wonderfully, installing it was a breeze. I have been more than satisfied with the lack of the spinning beach ball, and I am now able to work with many applications open. Thank you OWC, your RAM is wonderful.

Rating: 5/5 Perfect upgrade for my 2011 MBP March 7, 2017 Upgraded RAM from standard 2x 2Gb to 2x 4Gb. Received my order promptly. Instructions were clear. Installation went smoothly. Restarted the MBP and it was like a new machine. Now no spinning color wheel after the upgrade, which had become frequent especially after upgrading the OS software to Sierra.

Rating: 5/5 Saved my computer from the trash February 15, 2017 Buying memory upgrade from OWC saved my 6 yr old MacBookPro from being replaced. The price was right and the service was fast and complete. My comp is blazing fast now and can do anything I need it to do. $65 saved me from having to spend $1,500. Thank you O.W.C., and to my Silicon Valley nerd son for recommending them.

Rating: 5/5 Worked better than i expected December 5, 2016 I have a mid-2011 Mac Mini and it has been slowing down progressively. In the last 3 months, it had become almost unusable. Start-up takes 10 mins, program startup takes 3 minutes.

with this product, i upgraded the RAM from 2 GB to 8 GB and it has been a revelation. startup is now within 3 minutes and program startup is immediate. it has extended the life of my Mac mini.
