Your Mac wakes up on its own

Why it happens

A sleeping Mac can wake for network requests, such as another device on your Wi-Fi looking for shared files. Bluetooth mice, keyboards and USB hubs can also send a signal that wakes it. Some apps schedule tasks that briefly wake the Mac too.

How to fix it

1. Open System Settings, click Battery, then click Options at the bottom.

2. Set Wake for network access to Never, or to Only on Power Adapter if you need network wake-ups while plugged in. Click Done.

3. On an iMac, Mac mini or Mac Studio there's no Battery page. Open System Settings, click Energy, and turn off Wake for network access there.

4. For one night, unplug USB hubs and turn off Bluetooth mice and keyboards. If the Mac stays asleep, one of them was waking it.

Still not fixed?

1. Keep anything off the keyboard and trackpad, and remember a Mac laptop wakes when you open the lid. A bag that presses on the lid can do the same.

2. Quit apps that schedule backups or downloads overnight, or change their schedule in their own settings.

3. If it still wakes with nothing connected and network wake turned off, contact Apple Support. Tell them roughly when it wakes and what was connected at the time.
