It's not just VR where Macs are having trouble. Blizzard has historically been a bastion of Mac game development even when it was a niche platform, but Overwatch is Windows, Xbox, and PlayStation. For a bit of history, here are their Mac titles:
• Blackthorne
• Warcraft
• Diablo
• Starcraft + Brood War
• Warcraft II
• Diablo II + Lord of Destruction
• Warcraft III + Frozen Throne
• World of Warcraft + Burning Crusade + Wrath of the Lich King + Cataclysm + Mists of Panderia + Warlords of Draenor + Legion
• Starcraft 2: Wings of Liberty + Heart of the Swarm + Legacy of the Void
• Diablo III + Reaper of Souls
• Hearthstone
• Heroes of the Storm
And here's what they have to say about their latest blockbuster title, Overwatch:
> Currently with the technology behind Macs and the way Overwatch runs it's just too challenging for us at this point to support it. Our focus right now is entirely on PC, Xbox One and PlayStation 4. [1]
Mac marketshare has grown by leaps and bounds over what it was in the 90's, and Blizzard drops Mac support for the first time ever. Their last (well, only) game that shipped on PCs and didn't make it to Mac was The Lost Vikings in 1992 on MS-DOS. Overwatch is the only one to see a Windows release without Mac.
Bummer. Hopefully a port is eventually in the cards.
Overwatch is probably the most challenging in that list to properly port. Hearthstone isn't performance sensitive, frames per second and such doesn't matter, lag isn't an issue so long as it's not perceptible. In an FPS you're always slave to the clock, every millisecond counts, and the OpenGL support isn't there to squeeze what they need out of the mid-range GPUs.
Presumably this means Bizzard isn't interested in porting to Metal.
Last I heard, Blizzard ported World of Warcraft over to Metal with significant improvements. It wouldn't surprise me, though, if the relative age of the current Mac hardware is to blame.
