Rating: 5/5 Quick service April 10, 2017 I ordered this to increase the RAM on my husband's Mac Book. I am relatively comfortable with computers, but had never attempted before to change memory or other hardware. The item was perfect, easy to install and my husband's computer now works like new!

Rating: 5/5 Working well April 6, 2017 I wanted to update my 8 year old MacBook as far as I could so I fitted a 500GB SSD and wanted to expand the ram. Originally it came with 2GB which i later expanded to 4GB. El Capitan nearly killed it so I went back to yosemite. After reading posts here in the UK that said 4GB was the maximum, I read other posts saying with the correct boot rom version MB51.007D.B03 I could run 8GB. Tried Samsung cards but just got Kernal Errors. took the plunge and ordered OWC and bingo....works a treat! That's my Mac sorted for the next 8 years then! Thanks OWC x

Rating: 5/5 Thanks for the help March 29, 2017 This was my first time going inside my Macbook on my own. MacSales saved me a ton of money. Thanks for helping me identify the memory chips I needed for my machine. The installation was just as simple as your video tutorial made it look. All in all a great experience. I will be using MacSales for all of my future Macbook need.

Rating: 5/5 RAM has made a difference March 23, 2017 So far, so good. I referred to the site's video for installation instructions - installation was very easy and straight forward. The extra RAM (going from 4 to 8GB) has made a difference. I can't speak for long-term quality or performance yet, but at this point I'm very happy and satisfied with the product.

Rating: 5/5 Great Product, great service March 16, 2017 Had the early 2009 mac mini just sitting around my house and figured i'd try to fix it up. It was virtually unusable with just the 1 GB of RAM, so i opted for the maximum. I went for the 8GB which worked fine after I updated the firmware. I Installed the ram and upgraded from snow leopard to El Capitan, and its like a whole new machine. I wish I had ordered an SSD along with the RAM and done the upgrades at the same time!

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.

Reviewer: drewcarri Location: MI Experience Level: Noob Owned Product: over 6 months
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.
