Turn on a Mac mini, Mac Studio, or iMac without pressing its power button
You can configure some desktop Mac computers to turn on automatically when connected to power. This feature can be helpful when you don’t have easy access to the computer’s power button.
System requirements
This feature requires macOS Tahoe 26.5 or later and one of these computers:
Mac mini introduced in 2024 or later
Mac Studio introduced in 2025 or later
iMac introduced in 2024 or later
Set your Mac to start up when power is connected
From the Apple menu , choose System Settings.
Click Energy in the sidebar.
From the "Start up when power is connected" menu on the right, choose Always. This setting is available only on computers that meet the system requirements.
Your Mac will now automatically turn on whenever you connect it to power, such as when plugging it into a power outlet or restoring power using an external power switch. It will also automatically turn on when power is restored after a power failure.
If your Mac has remained connected to power since it was shut down, it’s best to wait about 30 seconds between disconnecting and reconnecting power to turn on your Mac. This gives your Mac power supply time to discharge.
