Right now, my basic needs are served by an iMac 24. About the heaviest thing I do is run Xcode, by which I mean stare at it while I read what I’ve done and think about what to do next. Idle time. I bet Xcode spends more CPU time on syntax completions than on actual builds, even with occasional build-and-run bursts. (For all I know, the occasional homebrew upgrade is the hardest this Mac has to work.) If I want to replicate the old iMac 27, my option is the new Studio Display and an M1 Mac mini. I could trade in this iMac for a discount. Then again, I could just get the extra display and pair it with the iMac 24. Or do nothing. I don’t mind the 24 inch display.
