By dissing it!
No, actually, I’m not even sure I fixed it, but I backed up my data and erased the HD and started clean, figuring if some rogue process was making it run hot, why not start by eliminating ALL processes? This also has the side effect of making it easier to sell if I choose to do so.
The reformat went surprisingly quickly. So far I have installed nothing, it’s just Safari and Photo Booth and whatever else Apple slaps on with the default install. The Mac is off right now, but I’ll check later to see if it is back to running cool. If not, it may be hardware-related or there may be unauthorized dust bunnies inside.
Also, I’m pretty sure the default mouse speed on a fresh macOS installation is calibrated for the original 1984 Macintosh 9″ display, because it is super weirdly slow.
Fun fact: Apple released no videos in 2024 to commemorate the Mac’s 40th anniversary.
