Rating: 5/5 Worked Great January 16, 2017 Even though Apple says that my Mid-2011 MacBook Pro can only take 8GB of RAM, OWC said it can take 16GB, and buying this excellent product proved that OWC was correct! Thank you.

Rating: 5/5 Don't buy less than 16GB of RAM January 16, 2017 I have a "early 2011" macbook pro. When I bought it I could only get 8 GB of RAM. I recently upgraded to 16 GB. I use a couple of apps that tell me how much free memory I have as I use my computer. Even with 16 GB I frequently find I am using over 12 GB of the available 16 GB. And yes I do notice a performance increase. Enough that I'm not sure I need a SSD.

I checked quality even though I have only been using the new memory a little over a month because the video on how to do the upgrade is great. It is a very easy upgrade.

Rating: 5/5 Works great January 2, 2017 I have a 15" Macbook Pro (Early 2011) and OWC recommended the correct RAM for my computer configuration: 1333 MHz compatible with my 2.0 Ghz quad-core processor (2720QM).

Installation was super easy!

Went from 4GB for to 16GB for just over $100, I should have done this sooner!

Rating: 5/5 It was "a piece of cake" installing the memory. So simple even a senior citizen can do it. December 27, 2016 I watched the video made available on youtube and saw that there was nothing to the upgrade that would be complicated. I made the installation myself in minutes and immediately had the memory I so badly needed. The computer is a bit over 5 years old but very serviceable and I'm glad that a company like MacSales is around to help.

Rating: 5/5 Best RAM upgrade December 11, 2016 So I was a little concerned when buying the 16GB But after seeing that OWC tested and "blessed it" I gave it a go. Worked amazing and the OS saw all 16GB and ran like a champ Thanks OWC for all the great things you do

Rating: 5/5 Exactly to Mac Specification December 4, 2016 Fast delivery, and exactly to specification.

Take care to select your vendor, there are products being sold that are labeled as 1333MHz, but are a little faster, and this will cause your system clock to slow, resulting in problems. MacSales is experienced / ethically enough to not do that kind of thing. (Read some of the reviews of other venders!)

Ibelive OWC provided me with help and guidance when i asked about recommendations and fitting.

conclusion, you need to upgrade your rams, this is the place to go!

Rating: 5/5 Easy install, great performance December 1, 2016 On my late 2011 MacBook Pro this memory upgrade (from 4GB to 16GB) was easy to install and I got a dramatic improvement in performance. Apple specifies max 8GB for my MBP but OS 10.12.1 which I am running recognizes the 16GB I installed.

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.
