We're currently researching a problem where Mac users change their game resolution, and then can no longer load the game. We don't have this fixed yet, but the workaround below will allow you to get back into the game. Just . . . don't change the resolution for now, and we hope to get this fixed shortly.

To resolve this issue:

1. Open up any Finder window, and type "Terminal" in the search window. Your Mac should find an application called "Terminal" that looks like a little black computer screen.
2. Double-click Terminal. You'll get a window full of obscure programmy stuff.
3. Type in this command, exactly as listed: rm -f "/Users/your user name/.Out of the Park Developments/OOTP Baseball 9/config/app" (don't forget the " marks and especially the "." before "Out of the Park," because that indicates it's a "hidden" folder).
4. Quit Terminal, and try loading the game again.
