I'm curious what you're trying to achieve here. My first thought was that you could change the target of the menu item so that it calls your own method, then call the original showHelp method with something like: [NSApp showHelp:sender] This still might not actually display the help viewer for example if it had been removed from the system, or if something made it crash before it displayed. I'm not sure what happens in those cases (an error in the log, or does it display an error alert?) Not very likely perhaps though. If you have to be more certain you might be able to view the active process list and observe whether it contained the help viewer after the call to showHelp. Alternatively maybe run a web server inside your app and make the help page load some object from it? It depends on how certain you want to be I suppose. :-) Perhaps others might have better ideas or could suggest another way of doing it.
