When/if Oculus ever restore Mac support add the audio SDK too. Investigate if there's anything we can do in the interim and if not then do a much better job that VR only works on Windows & add dialogs to the editor to inform users that this functionality is unavailable on OS X & prevent them from attempting to use it.
Try using Oculus on Mac.
