Anyone else facing the same problem? Seems to have started after the MacOS 26 upgrade: both when on power or on battery, closing the lid and allowing the machine to go to sleep mode, it then does not wake up and a restart is needed. Interestingly, the caps lock led seems to work, i.e. keyboard is responding, but screen remains black!
iPhone 16 Pro Max, iOS 26
Sequoia changed how the lid sensor (magnet + Hall effect sensor) reports its state to macOS which is the reason for the error. Putting this into my terminal helped :)
sudo pmset -a disablesleep 0
sudo pmset -a sleep 5
sudo pmset -a lidwake 0
sudo killall -9 powerd
sleep 3
sudo pmset sleepnow
Where is the fix???
Somewhere in Cupertino… they are hiding it from us.
This works! TY
Still not working for me sometimes, even after update. So frustrating.
Ce faci?
