Rating: 5/5 OWC Rocks July 16, 2017 I have been shopping with OWC since 1996. They have NEVER disappointed. I have purchased the gamut of items from them. Used, new and refurbished. Used Macs, RAM, HDDs, SSDs, mounting brackets, thermal sensors, processor upgrades. They have ALWAYS under-promised and over-delivered. I have recommended OWC to so many people who then become as fanatical as I am! They provide essential items that are direly needed in the marketplace who nobody else provides!

Rating: 5/5 Mandatory to Max Out July 13, 2017 After installing the OWC 256 SSD on my newly acquired 2011 iMac i7 2.8 Ghz 21.5 inch, I still felt that my computer was a bit sluggish. I have an external (500 GB) HD which still took about 4 seconds to load up. This was with 8GB of original memory. I read the reviews that others had posted and really wasn't sure how much RAM to order. I felt like maxing out my computer wouldn't hurt it and if I didn't notice a huge difference I could always return it. SUPER glad I ordered the 32 GB of RAM after I noticed the speed (less than a second) and ease in which I could now view everything on my external HD, while watching youtube videos and having multiple tabs on Safari open. Everything feels snappy. Like a 2017 iMac at the Apple Store snappy. My iMac was only $300 and after spending $380 on a couple of extras from OWC, I'm sure glad I didn't jump on a $1700-ish 21.5 inch iMac that would have been a PIA to add RAM to later on and would've practically looked exactly the same. Way to go OWC, keep up the great customer service, educational videos and ultra quality products.

Rating: 5/5 16 GB in my MacBook Pro early 2011 made it lightening fast June 14, 2017 I was having trouble with VMware bogging down so badly that I couldn't even move the mouse cursor. It worked sometimes, then bogged down and became all but inoperable. As an educated guess I decided to increase memory from 8 GB to 16 GB. Macsales assured me that even though Apple only shows that this computer is supported up to 8 GB, it only means they never tested it for 16 GB, and Macsales says they have done the testing. I can say that my computer is happy with 16 GB. It has breathing room now, VMware works lightening fast with Windows 7. My memory usage is now often up to 11 GB, so even though it never showed me maxing out my old 8 GB setup, and it did not show memory "pressure" to use more, my computer loves the space it has. I can get a few more years out of this computer. I hope you purchase this memory and your experience is as good as mine has been.

Rating: 5/5 Mid 2011 27" iMac ram upgrade June 12, 2017 Original system configuration came with 4GB of ram (2 slots with 2GB each). I added these two 8GB ram modules to the two remaining open slots. Now with 20GB of Ram system has an effortless feel within applications. I'm able to keep more applications running simultaneously with no lag. I also upgraded the drive at the same time with a hybrid HD from OWC. Between both upgrades, system is like new. The ram upgrade is very simple to do, and the OWC video how-to is very straightforward to follow incase you need it.

Rating: 5/5 Cranks now! May 17, 2017 Item arrived way sooner than expected. The OWC videos explaining the process for install were right on the money. I had just replaced the Keyboard in my MacBook Pro so, this was child's play, relatively speaking. The Mac was idle for 2 years waiting for me to get around to fixing the keyboard so was in much need of upgrades that wouldn't load because of the marginal memory. Adding the memory allowed me to upgrade the OS to Yosemite and now no more error messages when attempting to download needed software. Mac is VERY snappy now. Quicker than my abilities. No regrets here.

Rating: 5/5 Mac RAM great price, came quickly, worked great! April 13, 2017 I am a graphic designer, and my 2012 iMac was running extremely slow, making it difficult to complete jobs in a timely fashion. I was referred to MacSales from a friend who actually works there, after explaining the issues I was having. I ordered 16 GB of ram memory to install and hopefully resolve the problem. The price was excellent, and the product was received quickly without any issues. The RAM was installed easily, and I immediately saw an amazing increase in speed and efficiency, especially running my Adobe CS programs. The experience for me was excellent, and I would recommend MacSales completely for any Mac related items. They even sell refurbished Macs at a great price, and guarantee them. I have to say MacSales is my new favorite store!

Rating: 5/5 Worked like a charm April 13, 2017 Got a MB Pro from Ebay, noticed the memory was not as advertised. 4 gigs compared to the advertised 8 gigs. Popped over to Everymac for the specs and OWC for the parts. Got them in, replaced the 4 gigs, and suddenly it was like having air in the systems lungs. No need to free up memory ever 10 minutes, and can still work at the same time if I need to do so. Thanks OWC.
