Try downloading Wine, an application that helps run .exe files for non Windows platforms. Make sure to download the Windows version of the game. If you already have wine, try running "wine 'insertname.exe'"
Do you know how to use a terminal to use this input?
Oh I'm so sorry to hear that! Technially it should be alright, I just select the Mac build version for it. Seems I'll have to keep investigating the problem. It's hard for me since I don't have Mac, sorry!
