Please test this with iOS as well (Unity 5.6.4) before fixing this specifically for macOS. I suspect the bug to be related to the metal integration in general

I was going mad until I read your issue report here! I was trying to figure out why my builds were so slow compared with running in the editor (with the same settings).
It's happening for both 64 and 32 bit builds.
In my case, I was getting horrendous framerate issues on a build (down to 15fps), using Metal. Switching to OpenGLCore, I'm back to 60fps.
MacOS Sierra 10.13.1 and Unity 2017.2.0f3.
