Palmer continues to clarify what he meant by that blunt statement by saying “It just boils down to the fact that Apple doesn’t prioritize high-end GPUs. You can buy a $6,000 Mac Pro with the top of the line AMD FirePro D700, and it still doesn’t match our recommended specs. So if they prioritize higher-end GPUs like they used to for a while back in the day, we’d love to support Mac. But right now, there’s just not a single machine out there that supports it.”
The only Macs capable of handling the Oculus Rift built by Apple are 3 years out of production Mac Pros... or Hackintoshes. Those of us with either still have dual booting, so there's always that. I've come to the conclusion the 2013 Mac Pro's trashcan looks are a metaphor for what Apple thinks of professionals.
