Rating: 5/5 The upgrade I needed March 12, 2017 I was able to upgrade my mid 2010 Macbook Pro from 4GB to 8GB. Instructions were easy to read, and after watching a Youtube video i was able to change out the RAM myself. I highly recommend both the RAM and Other World Computing.

Rating: 5/5 What a difference! March 5, 2017 Just upgraded my 2011 MacBook Pro. Along with the RAM upgrade from 4 to 8 I swapped out the hard drive for an SSD. Prior to the changes everything was painfully slow. The boot time prior to the changes was 1 min 59 sec. After the upgrades it's 39 sec. All applications open right away instead of bouncing on the dock 3 or 4 times first. All in all it was about 4 hours from start to completing the Time Machine restoration. Highly recommended. My next upgrade is for my 2007 iMac.

Rating: 5/5 Rockin' Fast MacBook February 20, 2017 What a huge speed improvement. It is rocking fast now. For what I use this computer for, I should get a few more solid years out of it. The videos make installation a breeze. Also, I have had excellent follow-up from Customer Service, since my purchase. Great company!

Rating: 5/5 Quality upgrade works as expected January 26, 2017 I maxed out my memory capacity, from 4GB to 8GB, on my 2011 Mac Pro "15. The website makes the process of choosing the correct product very simple and easy to identify. I also called cust. serv. to confirm that I was purchasing the correct product and whether I could increase memory more than 8GB. They were friendly, helpful, and informative. I was also pleased with the rebate process of my old memory cards.

Rating: 5/5 Great product! January 11, 2017 I purchased this 8GB RAM upgrade for our MacBook Pro. Item was easy to find (as long as you have all necessary info from your computer prior to search), the video on the OWC website was excellent and made the installation very easy. I completed the installation in about 5 - 10 minutes, fired up the computer, everything works fine and it is now noticeably faster. Thank you OWC!
