    Seems many of us spend much time to install the variety of Unity versions to find if there's magical to make thing goes smooth. But still bad luck.

    Same issue here. Unity crashes every time I try to 'Build & Run'. I'm using MacOS Sierra and Unity 5.4.2f2. 'Build' still works.

    Tested with Unity 5.4.2f1. same issue
    Tested with the Beta 5.5 as well. Same issue.
    Tried to resinstall XCode 8. Same issue.

    Tried the different work arounds and doesn't work for me.

    Running out of solution.
