Oculus Rift on Mac doesn't work at all?

[zed_oud]

Fully updated, new Mac, steamVR installed. I've use plenty of other demos and games, and I've used the OR with TF2 when it was a beta feature (as -vr) on windows 7, ubuntu, and Mac. However, now I cannot get TF2 to see the OR no matter what; the "Virtual Reality Mode" option is always greyed out and disabled.

Worse, whenever I open "options", the game freezes for about 8 seconds, then the console outputs this:
"
Unable to initialize HMD tracker. Error code 301
Unable to initialize HMD tracker. Error code 301
ConVarRef hap_HasDevice doesn't point to an existing ConVar
Unable to initialize HMD tracker. Error code 301
Unable to initialize HMD tracker. Error code 301
"

Googling this last console line produces all of 10 results! Nothing!
Though this may sound like hyperbole I am not sure that anyone has had an OR work with TF2 on a Mac in the last several weeks.

Same here. I can't get TF2 to see the device at all. Completely sucks. I get an error 102 instead.
