You might want to choose a different run loop mode, if you have special requirements. NSEventTrackingRunLoopMode is sufficient to allow keystrokes and mouse clicks to be processed, so that you can have a UI (say, Esc key or button) to cancel the procedure if you want.
What is the difference between different modes? Is it performance or whatever else?

You should also see if -beginModalSessionForWindow:/- runModalSession:/-endModalSession: makes sense for your situation. It does require that you can do the time-consuming task in discrete chunks.
Do you have in mind that user can close a modal window while this task is executed? OK. I'll disable the "Close" button of the window and leave "Cancel" button active. Clicking on Cancel my time-consuming task will be aborted after the nearest iteration. Hope it will be enough.
