I can not run the Terminal.app after rolling back my system from time machine.
Mac OS X Version 10.6.2
It displays the following error. "Your are not authorized to run this application" "The administrator has set your shell to an illegal value"
After that I have deleted the file ~/Library/Preferences/com.apple.Terminal.plist
But the same message is displayed.
I have repaired all system rights with the DiskUtility but that did not help.
