Rating: 5/5 Just What I Needed September 12, 2016 I was dealing with a slow system but all that changed with this upgrade. The install video was great and made it easy for me to do it myself.

Thanks so much you saved me money.

Rating: 5/5 Great quality, great service! September 5, 2016 When I saw my product didnt arrived on time to Mexico, I asked for help. In less than 2 days I received it without any additional payment. I had only 4 gb of ram in my mac book pro. Now with the new OWC 16 gb ram, my macbook works better than ever!

Rating: 5/5 Why not? September 4, 2016 I decided to max out my RAM since the prices were so low. Easy to install, especially with the great videos OWC has. To be truthful, I really didn't see an increase in performance, but I don't really push my 13" MacBook Pro to it's limits anyway. What has helped in my case way beyond the memory upgrade was putting in an SSD. The speed increase is awesome and the prices are very low. There's nothing more i can do for my early 2011 model, but I'm hoping to get five more years out of it.

Rating: 5/5 Hasn't missed a beat. August 19, 2016 The new RAM was recognised as soon as I booted up, and since then has worked flawlessly. I also appreciated the low environmental impact packaging design, which was just right in terms of a balance between protection and environmental responsibility.

Rating: 5/5 No more disk swapping August 2, 2016 It takes effort to start enough software to make my Mac swap to disk. I started all the OS X utilities and programs, and then started Scrivener and Coda before I noticed memory being compressed. Starting Logic Pro too pushed it to swap to disk. After a system restart I reversed the software start-up order; Logic Pro first and then Scrivener and Coda, and then the OS X utilities and programs. Photos starting up began the swaps to disk. Every system needs 16GB, IMHO.

Rating: 5/5 Very satisfied! July 31, 2016 My MacBook Pro was running very slow and I was told that increasing the memory would help that. I went from (2) 4gb to (2) 8gb. It did make a noticeable difference! I was impressed with how easy it was to do. I thought, for certain, I would need to take it somewhere, but the directions and video were super simple to follow. Thank you!

Rating: 5/5 Been using this RAM for over 2 years and it's been fantastic June 1, 2016 Highly recommend adding more RAM to your iMac they are faster and much more stable with additional RAM. This RAM has been perfect and is still going strong. My next step is to add a SSD to my 2011 iMac to boost the speed.

OWC are a great company, I highly recommended them for all Mac products.

Rating: 4/5 I trust the compatibility checks May 22, 2016 Here in Canada, ordering something like RAM from MacSales.com is often more expensive and slower than ordering ram from a generic local technology vendor. But I trust that when I order something from MacSales, I won't have to take the time to triple-check that I'm ordering the right product, that it will work with the computer I want it to work with. I can just order 16GB of RAM for the specific model of mac that I want to upgrade, and trust that the right product will arrive.

In this case, that's what I did -- and I got what I expected. RAM that worked without any problems in my Mac Mini and took it barely functional under El Cap and brought it back to sanity.
