Splash screen, split second of VR and then crash

Every Unity project I've tried to build goes to the DK2 for a second and then closes straight away. No error messages, nothing. Tried a new project and empty scene, just ticking the VR box. Tried updating to the latest version of Unity, same issue.

The DK2 is hooked up to my friend's machine that doesn't have Unity installed, he's running 0.7 SDK and win 10. I'm making the Unity builds on my macbook.

Other demos built in unity that I've downloaded from Oculus Share seem to work fine.

Any help would be much appreciated.

 

Nevermind, problem solved. Needed to install the runtime on the macbook.
