I've installed XCOM: Enemy Unknown on a mac, and I'm trying to configure GameRanger so I can try starting a game, see if anyone else wants to play multiplayer.
Unfortunately, GameRanger doesn't seem to recognize my XCOM installation as valid. When going to GameRanger preferences, selecting XCOM, and then searching for it on my disk, this is what I see:
No matter what I do, the file remains greyed out and I can't select it. How do I fix this issue, so I can try and play multiplayer games of XCOM?
