Rating: 5/5 Significant speed-up to older MBP November 26, 2016 My daughter's old MBP (~2010) only had 4 GB RAM; I replaced with 2 X 8GB PC3-10600 DDR3 1333MHz SO-DIMM. Easy to do; fantastic speed-up in performance. Highly recommended

Rating: 5/5 Easy upgrade! November 21, 2016 I once bought an extra 8gb of memory for my mid 2010 IMAC and it was good. Though right now, it's getting a bit slower because of it's age that is why I decided to replace it with 16gb and what a difference! Less spinning of the colorful ball and handles most of the applications well.

Rating: 5/5 great product, good quality November 14, 2016 Is a good product, easy to install. already working as advertised. Even though on early mac pro 2011 17' is advised by apple to support max 8 gb ram this 2 modules totalling 16 gb are working great without any problems. I'm very satisfied by this purchase.

Rating: 5/5 worked as expected October 16, 2016 Website correctly identified memory needed for my specific MacBook Pro, and correctly noted that higher memory capacity would work despite Apple's statements to contrary. Memory cam fast and well-packaged; website installation walk-through enabled easy and fast self-installation without a hitch; Final result is improved performance as expected.

Reviewer: ChrisLJ Location: SW Ohio Age: 55-65 Experience Level: Home User Owned Product: 5-6 months
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!
