The game crashes on start on mac OSX when you have different "home folder" from your login name. Could be fixed by creating required folder and path and giving to it read and write permissions. /Users/login name(different from your home folder)/Library/Application Support/Book of Unwritten Tales After that the game starts and creates savegames and seems to work flawlessly. It still crashes on "quit game" but it doesn't have any impact on your gameplay.
