Rating: 5/5 Just stupid easy August 28, 2015 Opened the back of my Mac Mini - pulled one chip, installed this one - done. Now have 10GB when I only had 4GB before. No muss, no fuss.

Rating: 5/5 Really boosted my Mac's performance August 15, 2015 More RAM = a faster, quieter, more capable Mac. The OWC packaging was good protection but easy to open. Mac OS will use as much memory as you give it, and I like to have about ten applications open at once as I move between documents and tasks throughout my work day. Suddenly my Mac almost never needs to use virtual memory, so it runs quieter and cooler as well as faster, switching effortlessly between windows and apps. So glad I bought this!

Rating: 5/5 Easy and quick June 5, 2015 Bought to upgrade my mid-2011 mini. After all of ten minutes (because I was extra cautious) installation, the module makes the unit run s-o-o-o much faster. Recommend to all!

Rating: 5/5 Upgraded easily to 10GB March 5, 2015 Upgraded one of my older 2011 MacBook Pro's to Yosemite and decided to give the stock 4GB memory (2x2GB) a boost. I wanted the most bang for the buck so instead of upgrading to 8GB (2x4GB), I order a single 8GB module. Installed it into Bank 0 (the inside or lower slot) and kept an original 2GB module in Bank 1. Using OWC's install video made it a snap. Now I have 10GB for a great price.

Rating: 5/5 Help with Yosemite February 12, 2015 My wife's MacBook Pro was slowed to a crawl by the Yosemite upgrade. The extra RAM saved the day! Quick shipping and helpful installation videos made the whole experience enjoyable.

Rating: 5/5 Excellent June 9, 2014 I used the owc computer listings to find the right ram for my 2011 macbook pro. Asked an owc tech if the ram needed to be balanced across the two slots. He said no, so I ordered one 8g card. Took out one of the old 2g cards and popped the 8g in. Now I have 10g and it works great. The macbook is noticeably more responsive.
