Apple has just released a Graphics Firmware Update to address possible hanging on the iMac.
The freeze can occur during startup or after being woken from sleep mode.
The update will require a full reboot and takes only a few minutes to complete. The firmware update can be found in your Software Updates or if you require assistance, under the Apple Support section.
