Symptom
Pressing Command-Option-Shift-Power does not shut down the computer.
Solution
This Mac OS 9 feature is not implemented in Mac OS X, because Apple Pro Keyboards no longer have Power buttons. To restart or shut down the computer, you may:
- Choose Shut Down from the Apple menu.
- Press the reset button to restart the computer.
- Press and hold the power button on the computer for 6 seconds to shut down the computer.
The latter technique does not work on some earlier Mac OS X-compatible computers. On these computers, you may shut down the computer by pressing the reset button immediately followed by the power button.
