Works fine with iMac
I had HyperX impact ram installed previously (16gb x 2) for my iMac 27 inch 2017. I wanted to upgrade to 64gb but it was out of stock. I took risk and ordered this and installed it and it was working fine along with the old one. I ordered 16gb more and upgraded to the fullest. I run applications like Photoshop, Illustrator, PremierPro, Aftereffects etc and everything is smooth. Compared to HyperX it’s a bit highly priced.

After installation in my iMac 2019 21.5", it doesn't show up the manufacturer name
I purchased this for my iMac 2019 21.5".I installed the purchased (2x16GB) RAM using Apple Care, even though it is a well known (OWC) brand in Apple System, still the manufacturer is shown as 0. I also do not see the part number. I felt bad.The positive aspect is, its working fine. Already the Apple care team a very long to install me this RAM in my Mac. So I'm fine as it is working.
