Weirdly, despite not being able to tolerate much in the way of newer macs with newer Mac OS versions, the M1 iMac I used today at Best Buy running Mac OS 13.2 seems fine. Why? I have no idea.
Its the M1 model with 8 cpu/7 graphics cores in 8/256 config with the green color. The only setting that isn’t default is the accent color which is set to the furthest right color which is some sort of evergreen color. /shrug
