MacBook Pro M1 Max auto-boots after shutdown/sleep

to see if an Application is what’s stopping your Mac from going to sleep, follow these steps:

Open Activity Monitor. Be sure you show all processes

Click on the Energy tab

One heading should be “Preventing Sleep”

Click to sort by that column

See if any applications have a “Yes” listed in this column

I have a MacBook Pro M1 Max, and when I shut it down, it automatically boots up again. Even if I put it to sleep and close the lid, it still turns on by itself. I don’t have any peripherals connected.

I’ve tried reinstalling macOS (Tahoe 26.1), resetting and reinstalling again, and even downgrading to a previous version (Sequoia), but the issue persists.

old issue, new issue, what changed?

keep the Mac on the charger for all testing of the issue...

If the lid is closed how do you know it "still turns on by itself." ???

The current stable release of Tahoe including bug fixes, security updates is macOS 26.1

Thanks for your reply Leroy. I do have the most recent macOS installed (26.1) and in the dark I can see the light on screen when the lid is closed. Even if I click on "Sleep" when lid is open the screen goes dark and comes back. I've tried doing SafeBoot and Revive as well. Nothing worked!

I would not rule out a hardware issue...
