Programmer's Switches

Key combinations for programmer's switches that used the Power button on earlier models now use the Eject button. Here are the key combinations for the Power Mac G4 computer.

• Control-Command-Eject: restart immediately (reset)

• Control-Command-Option-Eject: shut down immediately

• Control-Eject: display the dialog box for shutdown, restart, and sleep

• Command-Eject: drop into MacsBug, if MacsBug is installed

The key combinations are decoded in software and may not be available under some crashed conditions. Therefore, NMI and reset switches are also available on the front of the computer.
