FYI, Unreal Editor 4.7.5 does not crash with Oculus 0.5.0.1 on my MacBook Pro (OS X 10.10.3) with NVIDIA GeForce 750M/Intel Iris Pro integrated, but I haven’t gotten it to show anything on the HMD in VR Preview or Standalone Game (“stereo on”). Of course the Mac is only supporting Extend Desktop mode, not Direct HMD, so maybe l just haven’t figured out how to make it work yet. The Oculus Demo Scene works in Extend Desktop mode though.
