It looks like a crash related to metal. When attempting to run the "01 - Camera.unity" scene in the editor on mac, a crash occurs.

The scene works fine on Windows & Android

What may be strange is that the scene also runs fine on iOS - auto graphics api was selected, but I believe that means it is being built with Metal too?

To reproduce:
1. Download attached project
2. Open 01 - Camera Scene
3. Enter play mode
