Upgrade the memory in an 21.5 iMac

問題

The stock 8 gigs is not enough under High Sierra for much more than email and browsing. Wanted to be able to run Virtual Machines of Windows 10 and some Linux distro

修理

I followed one user's advice and was able to exchange the memory without the full breakdown. I was able to loosen the motherboard screws and lift the board slightly, then pull and replace the SIMMs. Helps to have a good source of light and a little patience. No problems after the install.

アドバイス

The change in place method is possible. Just don't be in a hurry. There is the chance that you could damage the simm slot.
