Rating: 5/5 New MacBook March 28, 2017 The upgraded RAM definitely helped out my 2012 MacBook Pro. Apps are opening up a lot faster and even put the settings to max on one of my games. I believe a SSD will help it out even more, but that'll be later. And as for shipping, it got here in my deployment faster than I thought it would. Overall, very satisfied.

Rating: 5/5 Easy upgrade March 27, 2017 I put this memory in my 2013 iMac and now it runs faster. More files are stored in RAM cache and less time is spent compressing memory. Well, I'm not sure about that 2nd comment but it sounds good.

If you decided to do this upgrade, be careful with the antenna wires on the motherboard. One of the connectors broke for me and there is no easy way to fix it. So far, this has not been a problem.

Rating: 5/5 Great upgrade. March 19, 2017 I was not sure to buy 16GB RAM for my mid 2012 Macbook Pro 13" since Apple states that the maximum RAM allowed is 8GB, but is works perfectly. I recommend you to upgrade your Macbook Pro to 16GB RAM.

Rating: 5/5 So far, so good March 11, 2017 Of course, the proof will be in how the memory will be doing after a few years of use. I praise the OWC installation video, which let me see before ordering whether the installation was within my abilities.

Rating: 5/5 Great performance March 7, 2017 I changed my 4Gb RAM for this 16Gb RAM up grade along with a 1.0Tb Mercury Electra 6G SSD. The two transformed my 2012 MacBook Pro from a sluggish old machine to something I think will suit my needs for another four years!

Rating: 5/5 16GB memory fit well and works well February 27, 2017 I made a stupid error ordering my memory upgrade for my Macbook Pro. What I got was memory for a SERVER! The cards were almost as big of 1/2 of my keyboard! The company accepted the return and then I switched to MacSales and their great interface. I purchased, the items came, THEY WERE CORRECT, and when installed it worked flawlessly. I'm going to check to see if they have battery replacements! I hope so. I'd recommend this company to a friend.

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.
