Good purchase for MAC and Non MAC devices
Totally satisfied with product, I purchased 2 peace's of it and plugged them in my Intel NUC NUC7PJYH (non MAC) and that's it. It detected in a blink. No, issues so far. If you query this product in crucial website they will say its for MAC only and not supported for non MAC devices. But it works well. So if anyone interested in buying this, please go ahead as it is cheaper than non MAC version. Please make sure, your configuration is a proper match 2400 MHz, DDR4 SODIMM, 260 PIN, if this stuff matches you are good to go.

Great Economic RAM upgrade for Apple iMac 5K (Late 2017)
I have an iMac 5K 27 inch (Late 2017, 3.8 GHz) that I use for Music Production. It came with stock 8 GB RAM that wasn't enough for my multimedia projects. I ordered 2 x 8 GB Crucial RAM to add to the existing RAM of the iMac. Delivered within a day, installed in 10 minutes. The iMac booted up within 40 seconds without a fuss and Mac OS had detected the additional RAM. Now with 24 GB RAM, my iMac has enough headroom for my music production and the audio plugins I use in Logic Pro X & Cubase. Gaming performance has improved as well. There has been no lag or latency and no abrupt hanging on Mac OS X or Windows 10. My worry was that the RAM should work well with the existing RAM and there should be no abrupt system failures or reboots. But I am relieved and satisfied. I recommend this RAM for iMac 5K users. For the current price, it is unbeatable value.

Used for our iMac
Works beautifully. The installation on 2019 iMac was a bit tricky as you have to open everything...but apart from that the memory works very well. Getting good speed on the iMac.

Not for imac 5k retina, 27 inches 2017
I don’t recommend it to apple imac 2017 users, it made my machine mad. My imac stopped responding, ram will show in the memory that it has been updated but it will not actually work. I faced several problems when I installed this ram. My imac stopped responding, unable to turn on. This ram might be a great product for other computers but not recommended for imac 5k 27 inches 2017
