I don't currently have access to a Vive, but I worked with it earlier. All that needs to be done is add SteamVR to the project and hook up teleportation. That's it.
I may be fulfilling this wish, but I have not build a unity game to Mac in a while and do not have a mac powerful enough to run VR games. Can you download mac.app from here and let me know if it runs on your machine or if it works with SteamVR.
