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 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.

And even after 2 days of ordering up my memory MacSales had a special going on with Parrells software. I inquired if I might be able to get the discounted rate even though I had not asked for it during the initial purchase... without even questioning me MacSales automatically applied the discount and shipped out the software authorization immediately. I was and still am impressed with the excellent customer service. This is just another reason I like Mac over PC. Thanks guys and gals... you all rock!

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!)
