It is still technically more advanced and looks better than the vast majority of indie games and my point was that if something like Doom 3 (or Rage) can be made using OpenGL 1.5+exts (or OpenGL 2.0+exts, for Rage) then OpenGL 4.1+exts that macOS provides is more than enough for a ton of games. Yeah, it'd be nice if macOS supported OpenGL 4.6 and even better if Apple wasn't braindead enough to deprecate OpenGL instead of fixing one of the worst implementations (and still the only that has the core/compatibility divide that makes matters even worse), but even with all that taken into account, OpenGL on macOS is still capable enough for almost every game bar the more high end ones.
