I was looking into this,
will registering for a notification center like this inform me? Cause
it is not working so far.
And what type of apps will it inform me on?

[[NSNotificationCenter defaultCenter] addObserver:self

selector:@selector(NotifyMe:)

name:@"NSApplicationWillTerminateNotification" object:nil];

Is this wrong?

I think the name @"NSApplicationWillTerminateNotification" is wrong. If you use the predefined string NSWorkspaceDidTerminateApplicationNotification (defined in NSWorkspace.h) it will work as expected:

[[[NSWorkspace sharedWorkspace] notificationCenter]
addObserver:self
selector:@selector(applicationDidTerminate:)
name:NSWorkspaceDidTerminateApplicationNotification
object:nil];

In your selector "applicationDidTerminate:" you could e.g. do the following:

- (void)applicationDidTerminate:(NSNotification *)notification {
if ([[[notification userInfo] objectForKey:@"NSApplicationName"] isEqualToString:@"Safari"]) {
NSLog(@"Safari has quit!");
}
}

All terminating apps will be notified to you.
