    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.
