The Oculus Rift runtime for OS X is intended primarily for mobile developers who wish to develop for Gear VR on a Mac, and who would like to be able to run applications on the Mac for development reference.
Our development for OS X and Linux has been paused in order to focus on delivering a high quality consumer-level VR experience at launch across hardware, software, and content on Windows. We want to get back to development for OS X and Linux but we don’t have a timeline. For more information, see Powering the Rift on the Oculus Blog.
Note that this runtime was first released with PC SDK 0.5.0.1 Beta and has not been updated since March 2015. Compatible with pre-CV1 versions only (e.g., DK2, DK1).
