The mac build is using a WINE wrapper that Apple broke in High Sierra I think. I'll have to update it.

Crashes on launch with "EXC_CRASH (Code Signature Invalid)"
Can you build a version without code signing? Even in the latest macOs (High Sierra), you can run unsigned apps if you change the settings in GateKeeper. That's how I release all my mac builds still.
I bet the Windows version might work through Wineskin's .app wrapper too, which might be easy too..
