This firmware update has stranded my Air for a few hours on the apple screen with the processing circle rotating. How long does this update take and what should I do if there's a problem?

MacBook Air (13-INCH, MID 2011), OS X Mountain Lion (10.8.2)

    If you don't see a progress bar below the rotating circle, the firmware update isn't installing. Turn off your Mac and turn it on again. A SMC update shouldn't take more than some minutes
