crashes, patch won't instal

[Urkle]

It totally locked up the computer??? That's strange. it should NEVER do that... did you try "command tabbing" out of the game? Also can you run the "console" application on your mac (in Applications/Utilities) and see if there are any User Diagnostic reports for Penumbra Overture?

And definitely zip up the hpl.log from the Library/Preferences/Frictional Games/Penumbra folder, and the saved game files as well and I'll see if I can recreate it on my system.
