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!

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
I ran into the same situation on the mac m1 pro after upgrading to 26.0.1, the problem is with the display turning on. The cursor appears on the dark screen long before the rest of the image.
It does the same on my Mac Studio, so I don't think it has to do with the lid sensor
I also find that longer sleep times makes it more likely that the screen won’t wake. Even more so if there’s a program running and open when it sleeps. That could just be my imagination though.
Same issue here!! My Mac was absolutely fine and since the Tahoe update it has been crashing, having to restart every time after lifting to open my Mac!! Everything seems glitchy!! FRUSTRATING!! Come on Apple!! You are better than this!
Same issue here. Noticed it as soon as I upgraded. Turned off all the auto sleep options so it never went to sleep, which obviously avoided — but didn’t resolve — the issue. Then last night, force of habit put it into sleep mode instead of shutting down and now can’t wake it again. So annoying. Seems really odd that the only solution offered is to reinstall the OS. There have already been two OS26 updates I think — why has this not already been addressed?
Happening to me. Even reinstalled OS, checked login items, went through troubleshooting with Apple Support. Still happening sometimes, and I get a black screen with visible cursor upon startup.
I’m on an M1 Mac mini (2020). The computer is definitely awake; it’s just not sending a signal to the monitor.
I’ve never had this many big problems after an upgrade.
Sadly, this is not accurate... I thought that the problem had gone away after the re-installation... but it didn't. It is back again!
I now tried the sudo commands suggested by s4intdavid... let's see what happens... I will report back in a few days!
Overall, I am really frustrated that we are not getting a proper fix from Apple!
Additional comment.... The update has largely cleared the problems of touch recognition and sometimes waking up but not consistently and has now presented another problem... the Mac now doesn't go to sleep.
I agree with all who say this is unacceptable and gone on far too long. Apple needs to get its act together.
I facing the same issue and will NOT reinstall
I have the same issue. I noticed this a couple of days ago and put it down to a once off. This morning, it happened again. I am running a MacStudio.
I am having the same issue Mac mini m2pro. It doesn’t always happen, but I NEVER had this issue prior to TAHOE.
Same here.. I will not reinstall the OS...
same issue here on Macbook Air M4, I have to restart after sleep mode... very frustrating!!!
+1 for me on this issue. Getting it on my intel-based 2019 Macbook Pro.
Again, never had an issue like this apart from after upgrading to Tahoe.
thx your terminal commands solved the problem here
