Mac version has been updated to address:

1. Error dialog on Save/Quick Save (Overwrite case)
2. OS X Firewall nagging dialog
3. Crashes on exit

OS X users: We have identified a very nasty issue with Audio and it relates to Bink video playback. When your game crashes look at crash log and check whether crashed thread is in HAL::Audio territory. Please try to think what happened prior to crash. So far we see this crash only when audio devices in your system change - like HDMI cable plugged in/out.
