Rating: 5/5 Memory Upgrade for Late 2012 iMac December 19, 2016 My order for a 16GB RAM upgrade for my iMac came very quickly. I installed the two chips in my iMac very easily, thanks to the very nice video on the Macsales (OWC) website. The computer booted up as usual and when I checked the amount of memory, it said 24GB. It was 8GB. I believe this upgrade will improve my iMac performance while editing photos in PhotoShop. Thank you OWC!!

Rating: 5/5 Good Ram for Mac December 12, 2016 This was my third time ordering ram from OWC. The website design makes it easy to order the correct ram for the correct Apple computer. The prices are very competitive and shipping was fast( I live in Las Vegas, and I had my order in less than two days). I have only talked to customer service a few times, and both times they were professional and eager to assist me, even if I was not purchasing at that moment. As a mac/apple user this is my go to place for all things Apple. You will not be disappointed.

Rating: 5/5 easy peasy upgrade, and well worth it November 27, 2016 The upgrade was super easy and well worth it. I upgraded from 4G to 16G of RAM and included a new SSD with the upgrade. The memory upgrade alone made my MacBook Pro like a new machine - much faster and seems much more reliable. When the SSD was added - WOW - it's Super fast. Definitely recommend MacSales.com. They have good prices, they ensure the upgrades are compatible, they deliver fast, and they have videos that help a lot with DIY upgrades. I couldn't be more pleased.

Reviewer: Piccolo Location: Oakland, CA Age: Over 65 Experience Level: Home User Owned Product: 3-4 months
Rating: 3/5 Not very much faster November 26, 2016 My current MBP (~3 years old) had 8GB RAM, but seemed slow to me. After my excellent experience after upgrading other MBPs with OWC RAM, I purchased the 2X8GB upgrade kit. Why installation was easy, speed-up was not as expected. Maybe, I'll replace with HD with a Mercury SSD.

Customer Videos:

Response from MacSales.com, Technical Support November 28, 2016 If you're doing memory-intensive processes, then having more RAM will speed up those processes. If you're looking to get faster read/write speeds for data, then a SSD would help.
