cocoa - Notification when the system is idle or not on OS X -

i know there way scheme idle time iokit framework on os x, want know if there's notifications available.

i can create timer check if idle time more x, , that's fine. doesn't matter if observe idle mode few seconds later.

the problem observe when mac not idle anymore. want app show notification possible, not few seconds later.
