I tried this one but it doesn't seem to be doing anything, so odds are I am adding the observer wrong. I am a little new at this, if that wasn't obvious haha.
// Second notification, when the screens change
[nc addObserver:self
selector:@selector(handleBackgroundChange:)
name:NSApplicationDidChangeScreenParametersNotification
object:nil];
The handleBackgroundChange is just supposed to print a message with NSLog.
