Hmm, to be honest I don't know much how things work on mac. Do you still have this issue on the new update?

I'm also experiencing it on the latest public update. I found a different game that had a similar issue, apparently the dev had to tweak the mac export to compile for the apple chips(m1, ect). I have an m1 mac book air so that seems to make sense. https://itch.io/t/2158434/the-application-cant-be-opened-on-mac
