I have 2020 Retina 5K 27" iMac
I want to upgrade my memory. I have the original 2 X 4 GB memory modules now and am wanting upgrade. I couldn't find modules at the Apple store, apparently Apple doesn't sell the modules anymore!! That's crazy.
What are my options? Where and what modules are the best to buy?
iMac 27″, macOS 15.6
Macs can be picky about RAM, so I would suggest that you get more only from Orher World Computing.

Crucial once was another “go to” vendor for RAM guaranteed to be compatible with Macs, but they left that business.
