Hey! Thanks so much for the response and effort.
I know you have looked into already, but as far as I know you can completely ignore all the stuff about signing / notarizing the app and needing Xcode and a Mac. I think you can just export normally and than Mac users will have to run the app unsigned, which is how most indie stuff is exported to Mac anyways.
Feel free to not bother with the hassle, but in case you do look into again, I think it can be much simpler!
If you ever end up building something, I'm happy to test. Cheers!
Alright, you can give this a try then www.regnsloja.se/release/Xess_mac.zip
But if that doesn't work, there's not much else I can do heh
