2017.3 OSX Player crash at startup when Graphics API set to Metal

Hello, can anyone provide some insight in what is going wrong here? When we use Metal our game crashes before even loading the splash screen. Windows builds work fine and when building for OpenGL it works on OSX. We need to switch to Metal in order to get certain shaders to work. A copy of the log can be found here https://pastebin.com/rHtHRwim. Thanks!
