I have an issue with running Oculus DK 2 on Macbook, the latest version Oculus runtime. The issue is that I cannot change the display mode in settings, it is disabled. Therefore, when I run the demo scene, it is only display on the main desktop, nothing on Oculus Rift display. Please help!!!

Direct to rift is not supported on OSX. Rift works only as a second screen. For a quick howto on how to setup the screen look at http://mozvr.com/downloads/
Also, note that oculus on OSX is not supported for some time now, and things like firmware update on windows might break support on OSX.
