I have the same issue in MacOS with a standalone build too. (Works fine in editor for me too).

I have the same problem with Unity Standalone for macOS.
In the editor it works just fine. Only built app throws the exception.

I have the same problem with Unity 2017.1.0p4 and 2017.1.0p5
A workaround is to build with IL2CPP.
