Hello,
I have very little experience on that matter, but I have noticed on game jams that mac exports from godot cannot be opened in recent versions of MacOS, not directly at least. One has to be a paid, registered developer and sign the applications with Apple.
I was wondering if anyone has done this with a game from Godot. Is it doable at all? Is it difficult to do? Could someone easily do it for a steam game as well as game jam games?
