Rating: 5/5 Excellent January 18, 2016 I'm not very handy and avoid DIY projects whenever I can. But I ordered 16.0GB of memory for my Mac to regain some speed after a couple of system updates. The memory arrived as promised. I watched OWC's video on installing memory on my Mac and then installed it. All went well, my Mac and the new memory worked as soon as I turned the Mac on. I got some speed back, and I couldn't be more satisfied with OWC from start to finish.

Rating: 5/5 Improved performance and got a rebate January 13, 2016 I used to have 2 - 4GB chips that I bought from OWC. They worked well but when I upgraded my MacMini to 10.9, it slowed down a lot--annoyingly slow. So I bought these 2 - 8GB which maxed out my 2011 MacMini. At first I didn't think it was a noticeable improvement but after a few weeks I was aware it was much faster. And OWC is so great that I could return my old 4GB chips and got a rebate on it. The rebate is a bit of a pain to go through go I got the check fairly quickly. The only thing I wish is that I'd bought the 16GB the first time.

Rating: 5/5 LIKE A FERARRI! December 2, 2015 Bought this RAM and put it in my 2011 17" MBP, now its just as fast if not faster than a brand new 15" pro retina, I also updated the HDD with a samsung SSD and used the data doubler to put a 1TB hdd in the optical bay. Speed, Performance and reliability without having to buy a new MacBook

Rating: 5/5 Simple upgrade November 21, 2015 I had just upgraded a 21.5 iMac to 16 GB of RAM two months ago in Delaware when I upgraded the OS to El Capitan. I am bicoastal spending 6 months a year in California where I have a 27" iMac and I just upgraded this one as well to 16 GB of RAM. Probably the easiest computer upgrade there is to do. Takes 10 minutes or less. Tested the new RAM with TechTool Pro and with Drive Genius. Passed flawlessly. And they accepted my old RAM in trade-in.
