Similarly, couldn't you have the singleton itself register to receive
the applicationWillTerminate notification? I don't think it has to be
done via the app's delegate.
Something like:
(in your singleton's accessor, or perhaps a private initializer?)
[[NSNotificationCenter defaultCenter] addObserver:_singletonInstance
selector:@selector(appIsQuitting:) name:
NSApplicationWillTerminateNotification object:NSApp];
Then in your appIsQutting: method, just do:
[[NSNotificationCenter defaultCenter] removeObserver:self];

I had a very similar situation using a singleton and found that I
needed to remove it from the notification centre before the app died

would no longer respond to the mouse ).
I fixed it by getting the app delegate to respond to
applicationShouldTerminate: and removed my singleton from the
notification centre there. The menu problems went away.
