New Mac OS X: Mountain Lion roars at unauthorised apps

Gatekeeper only works when "quarantine bit" set

OK people, lots of hysterics as usual but just read that apps matching the criteria below will not be checked at all by the Gatekeeper.

* Anything already on your system is grandfathered in.

* Files transferred or installed using fixed media like DVDs, USB drives, and other portable media.

* Files downloaded by applications that don’t set the quarantine bit.

* Scripts and other code that isn’t executable.


So if your favourite file download client (e.g. BitTorrent) doesn't set the quarantine bit, Apple's gatekeeper doesn't get involved at all.
