Scheduled startup not working (Big sur)

Hello, I've been using Mojave for a long time and had my MacBook Pro to automatically turn on before I wake up (because I have it in clamshell mode and it's easier that way).


This week I updated to Big sur and cannot make scheduled start up work anymore. I wake up and the macbook is off, I have to take it out from the laptop holder, open it, turn it on and plug it back again which is annoying.


I have it plugged to a USB-C screen and haven't changed anything on my setup, other than upgrading to Big Sur.


What can I do? These are my settings, they're in spanish but the position is pretty much the same in english. Maybe I should turn powernap off or something?


Any help would be really appreciated.




MacBook Pro 15″, macOS 11.2

Greetings, and welcome to Apple Support Communities MauroPerez!


From your post, you’ve noticed that your scheduled startup hasn’t been working since you’ve upgraded to Big Sur.


Thanks for sharing the screenshots! It helps. We wanted to share this guide: Schedule your Mac notebook to turn on or off While looking this over, you’ll see there is a reference to “Restore Previous Settings”.  Let’s see if this will help enable the startup to begin again. We’d want to make sure all documents are closed on the day prior, then test on the next scheduled time. 


You did ask about Power Nap.  You can learn more about it here: What is Power Nap on Mac?  You can use this to decide whether to turn this on or off. 


We hope this helps!
