Can't restart or shutdown/anything help!???? It said somethingike attempting to Make movie HD quality this may take several minutes now it's frozen :(
Press and hold the power button for up to a quarter minute and your Mac will power off.
Hold the Shift key at Startup to perform a Disk Utility (Repair disk) on the boot drive (takes about five minutes) and then boot into Safe Mode.
