And, like, Apple ported OpenGL to Apple Silicon macs. I suspect it's going to stick around, it's just never, ever going to get updated.
You're kidding. The OpenGL implementation/support of Mac is pretty nonexistent/poor.
It’s OpenGL 3.3. It works as well as OpenGL 3.3 does anywhere else. It’s an old version, but it certainly exists, and it’s what many/most Mac games still use because it’s cross platform.
