yo Jack2000... I know you're working really hard... believe me a fellow dev knows but. When you say it supports mac, its gotta support mac. The .exe files are for Microsoft. I checked the file info and none of the stuff are for mac. (the stuff that's supposed to run the app). It's an easy fix. You just gotta switch the unity build to mac and add that to your itch page as well. One download doesn't work for both you need two different builds. Hope this helps! And keep going your incredible!
