A-Tech 16GB Kit (2x8GB) RAM for Apple MacBook Pro (Mid 2012), iMac (Late 2012, Early/Late 2013, Late 2014, Mid 2015), Mac Mini (Late 2012) | DDR3 1600MHz PC3-12800 SODIMM 204-Pin Memory Upgrade

Installed in my Apple iMac 27 5K without a hiccup. My apple boots up right away, definitely a great buy and was delivered on time.

Bien

I’ve been wanting to upgrade my computer ram for a while now and decided to pull the trigger and get this. Was really happy with the price. I expected it to make my computer a lot faster but it really didn’t do anything too noticeable yet.

this worked perfect in my iMac late 2013

My Mac book started slowing down loading websites and skipping during movies. This occurred after I did an operating system update. I went into the computer monitors and saw that all the memory was being used up. So I ordered these memory sticks. Works great! Totally fixed my problem. The hardest part was unscrewing the bottom cover of the computer.

It crashed my MacBook computer, I cannot use it up till now.

I had 4GB with High Sierra 10.13.6, model A1278 MD101LL/A. I put two 8GB modules in for a total of 16GB, and it is smoking fast even without an SSD.

I bought it in August 2016.. It worked very well until last week in 4 months my macbook pro wont start, when I put my old memory back it worked, so basically the memory just went bad on it own. Does not look like a reliable product.. if works then works if you get a bad memory it may not work longer..

My MacBook pro was really slow, and it was really frustrating working, or just browsing the web. Everything took forever to download. This card did the trick for me. Everything is up to speed. I was skeptical after reading some of the reviews, but I am content with the results.

Wonderful product, beyond my expectations
