The only way to play such a build on macOS is either to sign it or to get all users to run xattr -cr on the .app
Thanks for that tip. I'm going to try to get a signed build or somehow at least a Windows build out next week for people to play it.
Signing windows build is usually the most expensive as you have to purchase an E.V certificate and they don't come cheap.
How do people share these builds then? Just unsigned EXEs?
