Apple didn't like OpenGL, rightfully, and came up with their own Metal which they released two years before first version of Vulkan was released.
Now people pretend that Apple is bad because it never adopted Vulkan and never implemented the "good modern OpenGL" (which never really existed).
My absurd pet theory is that this was related to their 2017-2020 dispute with Imagination. Apple started (allegedly) violating Imagination's IP in 2017. They were, at the very least, threatened with a lawsuit, and the threats were compelling enough that they've been paying up since 2020. It could be Apple pulled out of the Khronos IP pool to prepare a lawsuit, or to have better chances of dodging one.
It runs deeper than that, during the development of WebGPU it came to light that Apple was vetoing the use of any Khronos IP whatsoever, due to a private legal dispute between them. That led to WebGPU having to re-invent the wheel with a brand new shader language because Apples lawyers wouldn't sign off on using GLSL or SPIR-V under any circumstances.
The actual details of the dispute never came out, so we don't know if it has been resolved or not.
