Exceptional Apps

Daniel Jalkut:

How does this kind of “blacklisting” occur on Mac OS X 10.8? I suppose in the future we might see restrictions that tie in to the new Gatekeeper signing system, but that is of no help if the targeted apps are not signed. The current mechanism is in the form of a crude XML file installed by Apple in your System folder:

/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/Exceptions.plist

There are lots of interesting overrides there.
