"sleep" greyed out...Mac stopped going to sleep

This helped me!
1. Log in with an account that has admin privileges

2. Open Terminal and run the following command:

1	sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.PowerManagement SystemPowerSettings -dict SleepDisabled -bool NO

3. Restart the Mac (this is necessary to apply the change.)

After the restart, you should see that the Sleep command is available again in the Apple menu.

Worked well. Thank you.

I owe you a beer! Thank's mate!

16' MBP - I noticed my laptop wasn't sleeping for some reason (losing 10%+ every night and keeping external monitors on when I'd log out) and sleep was disabled in the menu. pmset -g shows that it was disabled system wide - I don't know by what!

The sudo command in Srini's post helped (after a reboot).

Thank you.

Worked smoothly! Thank you so much bro! I had been having this problem for a very long time now and couldn't find any ways to fix it online, until I came across your solution. Super happy that it works now. 😄
