Regarding iMac (Retina 4K, 21.5-inch, 2019)!
An Apple customer told me that I could add more memory individually, but I'm not sure if I can. How is it?
iMac 21.5″, macOS 12.3
The RAM in that Mac is considered non user-accessible and should only be added by an Apple Authorized Service Provider willing to do it.
