if its not the regular cant verify crap, check in the MacOS folder.
1. right click and select 'show package content'
2. follow folders till you are inside 'MacOS' folder
3. if it doesn't look like the terminal app it isn't the right executable, change it by doing some crap in the mac terminal or get iterm
to change the executable first you wanna move the game to the desktop for ease of access
then open a terminal and type cd Desktop then press enter
then type this command chmod +x "game name".app/Contents/MacOS/"Whatever the incorrect executable is called"
