Forum Question: How Do I Stop My iMac From Randomly Turning On

imac just plugged into surge supressor no ups.
during a thunderstorm i had the imac off.
the power went out to the house for 30 seconds. when the power came back on to the house the imac turned on.
I want to find the software setting that triggered it to turn on after the power returned to the house, as i don’t want it to power on in a storm and then have the power go out again possibly causing a glitch on the harddrive if it was writing to the hard drive.

    Look in System Preference, under Energy Saver. It is called “Start up automatically after a power failure.”
