I want to get some notification in my Cocoa app when the user changes some of the user defaults from the Terminal by using "defaults write ....". Is this even possible?

  • Did you try whether this approach works for you: [Notification on NSUserDefaults value change](http://stackoverflow.com/questions/1141388/cocoa-notification-on-nsuserdefaults-value-change?rq=1)? – Jay Apr 02 '13 at 07:19
  • I did try it but it doesn't work when the defaults are changed from the terminal. – icocoa Apr 02 '13 at 08:31

I'm not sure if it's possible. You should try using key-value observing (KVO) on NSUserDefaultsController. You would observe the +sharedUserDefaultsController for changes in the key path values.<your default key>.
