Please check the instruction above download links. The problem is with how Unity was signing Mac builds. If you follow the instruction it should fix it on your end.
I'm afraid that doesn't seem to be fixing it. The terminal output says "Not enough arguments for option -d. Expected at least 2 but got 1". I've no idea what any of that means, but I gather the command isn't functioning as intended, and the game still refuses to open.
Incidentally, I don't think it's a Unity issue. I've played other Unity-based AVNs without having this problem.
