Mac keeps going into Do Not Disturb Mode

TLDR solution! - Uncheck and recheck "When mirroring to TVs and projectors." under Notification Preferences > Do Not Disturb > Turn on Do Not Disturb.

Full story:

This started happening to me today as well. Per the various comments I had the exact same issue - Do Not Disturb was enabled according to the Touch Bar (and notifications not coming through), but Control Center didn't show anything selected. If I clicked the lit-up moon icon on the Touch Bar it went dark for literally a second or two, then lit itself back up again. I rebooted twice to no effect. I tried disabling via terminal and I could watch the Touch Bar DnD icon turn off for a second but then turn itself right back on:

say 'sleep 1' && sleep 1 && defaults -currentHost write ~/Library/Preferences/ByHost/com.apple.notificationcenterui doNotDisturb -boolean false && say 'Disabled' && sleep 1 && killall NotificationCenter && say 'Done'

(The "say" and "sleep" commands are so I could know exactly where I was in the script)

In Notifications preferences, the only thing that was checked was the box to turn on Do Not Disturb "When mirroring to TVs and projectors." I was not mirroring anywhere (and probably haven't for many months), but I unchecked it and Do Not Disturb was disabled! I rechecked the box and Do Not Disturb stayed disabled and now the various Control Center options, e.g. turn Do Not Disturb on for one hour, until tomorrow, etc. now worked and stayed lit when selected. (Per above, until I made this change none of these items ever showed up as selected and clicking them had no impact.)

Couldn't explain root cause other than I think somehow macOS got confused and thought I was mirroring and absolutely could not be convinced otherwise until I cycled that setting. Hope this helps others.

Tried this? Click on the Do not disturb icon, click on Notificationspreferences and deselect the options

Did you try turning on "Do Not Disturb" in the Control Center then turning it off again?

Click on the little arrow on the right side of 'do not disturb'. Then click at the bottom of the new window on Notificationspreferences

Turning off mirroring did not help for me. I have the same issue as described originally: at each startup, do not disturb turns on by itself. I tried scheduling DND for 5 min in the middle of the night, did not help. Unchecked everything - the moon still returns after restart. The only temporary fix I found in another thread is to put any window in full screen mode, which resets the DND. I now have to do this every time I restart my computer... A permanent fix is needed.

Thanks for the suggestion. I tried, and Siri replies "OK, I turned off do not disturb" but the moon remains and notifications still do not come. I tried asking Siri again and again and the reply is the same. The only way to actually remove DND is to turn on hiding of menu bar or go to full screen.

The same thing is happening to me. There is no way to turn it off in the Control Center because nothing is lit. I also don't have any notification preferences checked. The only indication that it is on is the moon icon. I did use Siri and asked her to turn it off. That worked once, but then it came back on and the next time Siri brought it up and said she turned it off, but she did not. I was able to move the button manually after a few tries, but the moon icon is still there, even though I moved the button to off.

Did you not see my post and screen shot?

My post has nothing to do with Notification preferences. Plus you replied to mulberry58, not me.
