Instead of the very expensive Apple memory, use this memory to upgrade your iMac.

Work perfectly, critical help desk at the right memory

No regrets buying Crucial memory

Excellent memory upgrade for an iMac at a good price

As usual Crucial memory has worked flawless for me

Great memory value for the iMac.

This memory is working fine in my 2017 iMac 27".My iMac now has 40GB total RAM: 8GB from Apple + 32GB Crucial

The installation process was smooth and the memory did not give me any trouble after installation.

After an email from Crucial confirming it was the proper memory, I ordered it.

And indeed, after I installed it, the memory was recognized immediately, and it works together with the default 8Gb that was factory installed

The memory was effective immediately and I notice fast loads and rendering!Perfect upgrade for my photography/videography business!

The memory work perfectly with my new 2017 iMac computer

after a patient (but silently panicked) wait it fired up, reported the right memory amount, and runs great.
