This is an Easter egg that occurs randomly at start up. Did that other problem fix?
Oh wow. That's honestly really cool. But no, I haven't been able to fix the problem. I've deleted the application after making sure it was properly exited, then I had re-installed it again, with no luck. I've even tried fixing the resolution thinking that was the problem, gamma, and I have recently updated my Mac thinking that was the issue, with no luck. I have no other options :|
I don't really have a Mac to test this on. This version was processed for Mac by request but I wasn't able to do tests on it. The person that requested it didn't really say anything about this type of problem. I would suggest downloading VMware for mac and emulating a windows system and that should work for playing the game with compatibility supported.
