I have a few of these to share. From oldest to newest.
iMac G3:
How did you change it to "macOS"?My 2011 is in the living room in clamshell mode still on Yosemite. Saved this 2010 from rotting in a closet because of the graphics card problem. Funny enough, the 11.4 update that came out awhile ago made it more stable. It's nice being able to use Safari without the NVIDIA card kicking in.

Non-upgradable for this model. The same was true in El Capitan.No 'Memory' tab?
