i ordered the complete package in steam. i am using mac os and an 27 inch imac. problem 1 is that you cannot navigate through the game-menü with resolution 2560 * 1440. you have to reduce it in mac os to 13xx * 7xx to edit the settings in episode 1 and 2. ok but this was manageable.
problem 3 is episode 3. i start a new game. the game quit and generate an bug report. this is very annoying. if you change the resolution the same.
i have play episode 1 and 2 without crashes and problems.
yeah i am from germany an my english is ... horrible.
i hope some technical exp. user has any suggestion.
