I have a MBP 2018. After upgrading to Catalina, when unattended with the power adapter connected, after a while the machine will start chiming every ten seconds and displaying a '100% Charged' message on the screen.

It's driving me nuts. How can I stop it?

Weirdly, I can't find any references to this online; there are even some references to people wanting such a notification. It's a new installation, so I don't think there's any custom software doing this. Is this a new Catalina feature?

  • I was going over the release notes for Catalina 10.15.5 and.6 and can't find anything about battery full notifications. I only know of 3rd party apps that do this. Can you confirm by booting into Safe Mode (hold Shift while booting). If it stops, something is being loaded at boot that causes it. – Allan Oct 10 '20 at 21:24
  • I've not seen any such notifications, either. – benwiggy Oct 10 '20 at 21:42
  • I tried safe mode, and it still happens, but I didn't get any notifications that safe mode has been entered, so maybe that didn't work? I do notice that I can provoke the message by unplugging and reinserting the USB-C cable. – David Given Oct 10 '20 at 22:36
  • There's no notification for entering Safe Mode. So, in Safe Mode, it will send a "Full Battery Notification" when you unplug/plug the charger? Three things...can you verify your macOS version (click Apple logo → About this Mac) and can you try creating another user and see if it happens there. Also check to see if it happens when not logged in (don't sign in and remove/reinsert the charger). Does it give you the audible alert? – Allan Oct 11 '20 at 7:52
  • One last thing... use @name (@Allan for me) to ping users in comments so we get notified when you respond. – Allan Oct 11 '20 at 7:53
