Crucial RAM 64GB Kit (2x32GB) DDR4 2666 MHz CL19 Memory for Mac CT2K32G4S266M

Installation took less than 3 minutes . I have a 2017 iMac 3.8 ghz and I inserted the ram in the open slots , did not move the original Mac ram at all . Closed the back up , hit the power button and it took about 30 seconds to boot up and recognize the the memory and like magic there was the apple logo on the screen .

Ordered a single 8 gb, added to my existing two apple 4gb(4x2) for total 16 for my 27 5k, 3.8 hz 2017 Imac. Worked flawlessly for primarily Photoshop cc and LR cc!

What can I say, I paid for them, put them in and my computer shows what is suppose to be in it and it runs way faster.

iMac working great with the additional memory.

I installed it myself and it was fairly easy. It worked great. My main concern was that I would order the wrong thing but the specifications in the description were right on.

I bought a 27 iMac at Costco that only had 8GB in it. With 24GB, its now noticeably faster. These installed in about 10 minutes, no problem.

What else is there to say? Easy and cheap plug and play memory for the mac mini.

Awesome product and easy to install!

Installed in my 2017 27 iMac combine with the stock 8GB from Apple for a total of 40GB. Moved the stock 4GB modules to the second and fourth slot and installed these in the first and third. It booted right up without any issues. Ive been running it for 2 weeks free from any problems. I would recommend this ram for those you who run a Mac because you value stability and reliability. There may be better CL ram out there, but I figured one single issue will eat up all of those saved nano-seconds and then some....

Works great! No problems.
