[Mac] Editor crashes on MTLGetEnvCase<MTLErrorModeType> on startup when metalEditorSupport is set to 0 in the ProjectSettings

Graphics Device Features


Reproduction steps:
1. Create a new project
2. Go to Project's root folder > ProjetSettings > ProjectSettings.asset
3. Find "metalEditorSupport" and set it to 0
4. Open the project
-- Observe the crash

Expected result: the Editor should fallback to other Graphics API or prompt an error message informing the Metal API support is disabled

Workaround: go to Project's root folder > ProjetSettings > ProjectSettings.asset, find metalEditorSupport and set it to 1

  2. Resolution Note (fix version 2019.4):
