We really should just start calling non-conformant graphics API implementations (like Apple's OpenGL, or MoltenVK) "buggy".
If code doesn't pass tests we usually call that a bug and don't ship it until it passes them, right? It is exceptional that Apple is shipping OpenGL drivers that don't pass the tests and they are okay with that. They shouldn't really get credit for supporting "OpenGL 4.1" when they literally fail the OpenGL 4.1 tests (they even fail the OpenGL ES 2.0 tests!).*
Nobody actually knows how to compile/run the full test suite on macOS OpenGL (because Apple would be the only entity who would care about that, and they don't), but we do know for a fact they have bugs the tests test for, so we can confidently say they'd fail the tests if someone were to actually port/run them.
