For some reason Apple seems to pay no attention to anything other than casual games. They completely crippled the mac gaming scene which was doing OK when they killed 32bit and never implemented vulkan support. IMO they can't embrace VR without going back and helping the game developer scene in getting the tooling they need to make mac support easy.
At some point, probably. Very unclear when and what it looks like at this point. Aside from niche commercial use cases, I certainly haven't seen anything that especially interests me.
