RetroArch has versions for both ARM and Intel based Mac’s. You shouldn’t have a problem playing up to Dreamcast, possibly later. There is a bit of a learning curve, but RetroArch is on pretty much everything now, and it’s worth learning.
I have the same TV and built a custom stand for it. Doesn’t change the fact that the included stand is a bad design.
