title: I'm unable to move the cursor in play mode in the Unity VR example scene
body: <p>I'm using the VR Samples from Unity <code>https://www.assetstore.unity3d.com/en/#!/content/51519</code> with the scene 'Shooter 360' (though I've tried the other scenes). </p>
  
  <p>I'm on a Mac and in XR settings I have both 'Mock HMD - HTC' and 'Oculus SDK' supported. </p>
  
  <p>When I press Play, I'm unable to move the cursor or interact with the GUI at all. Any recommendations?</p>
