My Intel iMac, 27", mid-2011, running OS X 10.7.4, won't shut down or restart. The machine always hangs up with the spinning gear. To shut it down, I must use the power button. To restart I must shut it down with the power button and then press the power button again to restart. The machine goes in and out of sleep with no problem.


Any ideas what can be causing this behavior and how it can be corrected?
