Apple Quietly Just Gave Your Mac an Unexpected New Feature:
With the new Power Control setting turned on, your iMac, Mac Mini or Mac Studio will automatically turn on when reconnected to power. So if it’s off, you can just unplug and replug it into a power outlet and it’ll automatically turn on. It’ll also automatically turn on if your house loses and then regains power.
Genius! Now if only they could find a fix for the mouse.
