Right click on the game, you will see "show package contents", click that. Open the content folder. then open resources, which will lead you to the autorun folder. In there is the Game folder, take the game folder from the pc version, and replace your old mac "game" folder with it. The barebones of the game hasn't changed, only the game. I hope this helps.How exactly? There isn't a "game" folder in the mac version download.
