One they missed that I got burned by and am still bitter about: a few years ago (I believe macOS Big Sur) they just up and removed support for 1080i displays. No hardware change, one day 1080i works, you “upgrade”, and then 1080i is suddenly gone. No explanation, just because fuck you, user, I guess.
Thank you, whoever you are on the Graphics & Displays team, for your excellent contribution to the code.
