my mac mini on m2 automatically wakes up after 10-15 minutes every time, how can I fix this? What could be bothering him?
Every time? How about at the lock screen (a.k.a. login screen). From the lock screen, put the Mac to sleep. (If you don’t see the buttons for this, go to System Settings -> Lock Screen, and near the bottom, turn on “Show the Sleep, Restart, and Shut Down buttons” switch.)
If the Mac still wakes up after a while, there must be some automatic task that is causing the Mac to wake after a while, probably network-related. You can also try this after a reboot, from the login screen.
