Take a look at -[NSApplication beginModalSessionForWindow:] and the friends described in the docs for that method. This lets you start a modal window, run it at intervals to keep events processing, then close it when done. Of course this requires putting your progress bar in a modal window, but if you're not going to allow the rest of the program to run then this is a good idea anyway.
