That might explain it, I am a Windows user. I used to use a Mac but didn't have any VR compatible games then. I am unsure of how to fix this problem on a mac. Sorry about that. I'd read something on the internet about VR on Mac's, but I havn't tested it myself, as I no longer own a Mac. You could try using Big Picture mode in steam (top right of the steam app), to see if it comes up when launching, otherwise, I don't know how to fix this problem.
