My app has a child object that handles a periodic process on a
separate thread. From time to time that process encounters an
error which requires notifying the user and quitting the app. So
far I've done this with an NSAlert from that thread, and then
[NSApp terminate: self], which seems effective.
The trouble is that there are some things that would be good to
tidy up in the main thread before even showing that alert. How can
I have this child object, on a separate thread, tell the main app
to do some stuff, show the dialog (with error data from the child
object), & quit?
Thanks,

Set a flag in the NSApplication delegate, to signal abnormal
termination,
and implement the cleanup in the applicationWillTerminate:
delegate method.
This only works if you can wake up the main thread somehow. It's
better to use performSelectorOnMainThread:withObject:waitUntilDone:.
