Mac OS help

I appreciate the detail that went into this guide! I’ve run into a slight issue, though. I’d been running the game fine, through the Windows core, but it wasn’t opening for me today, maybe since I updated the OS X beta. So I figured I’d give this a shot, but when I get to the “Install Software” portion of your guide, when I point it to my Insurgence folder, the move fails and it throws an error:

“You either do not have permission to move, or there is already a folder with that name in the wrapper’s Program Files folder”

Of course, permissions are not likely to be the issue here and, as far as I can tell, there’s nothing that even sniffs of the name Insurgence in the recently-created wrapper. What’s the deal here?
