Isn't this a little odd? I'd expect you to be using /usr/bin/ hdiutil (or whatever) as the launch path, and not pass hdiutil as the first parameter.

One can use both approaches, not really related to the problem I have.

If you say so. Just pointing out possible points of breakage.

What I do is unregistering an object as observer from all entries that specify NSFileHandleReadCompletionNotification as notification name, hence including my file handle I previously registered the object with. Again, one can use both approaches in this case, not related to the problem.

I vaguely remember there used to be a bug where you had to have the two balanced. I.e. if you registered with a notification object, you had to unregister with one, too, or something got out of whack. I'd presume that's been fixed, but it might be worth a shot. If it's been broken once, it may be broken still.


Have you tried testing it without the notification? What happens if you use readDataToEndOfFile: or something like that? It might not solve your problem, but at least it would help locating the actual point where the error sits.
