Thanks, Mukizium.
I know that the OpenGL implementation for MacOS has been stagnant for years, nevertheless it has provided a convenient way for me and many others to build simple portable apps without re-coding in Apple's proprietary languages (or MS DirectX, which would be far worse). Even for the subset they have implemented, Apple has not always respected the standard, nevertheless the workarounds have been quite bearable.
Apparently OpenCL is not dead yet either. I know a guy whose multiplatform app, that uses OpenCL for heavy computations, seems to be running fine on M1 Macs. He even told me Apple's implementation is less buggy than nVidia's. It is odd that Apple, the actual creator of OpenCL, should not even mention it once on their main or developer websites. Scared to appear old-fashioned, I guess.
