My G5 iMac running 10.4.4 starts up at 3 am each morning to perform routine and periodic maintenance. How can I stop it doing this?
System Preferences application. Energy Saver panel. Options button. Turn off the "Start up or wake" checkbox. Then find out what turned it on in the first place and make sure it doesn't do it again, because that behavior is by default off.
