Q. Hello IT Support, I know there's a feature in BIOS for PCs to be turned on after a power outage. Is there such a function in a Mac?
A. Yes, this is a useful feature to have for remote computer access. If you login with an account that has administrative privileges, you should be able to do that. Go to:
System Preferences > Energy Saver
and select Start up automatically after a power failure. This will ensure that the system comes back up after a power outage.
