Annoying notification of updating mac os x Mojave

Question

I am using MacBook Pro with mac os x Mojave. Having a lot of 32bit applications, I don't want to update Catalina but having the annoying notification. I have unchecked software update still it showing. Is there any way how to stop it.

Answer 1

1. Navigate to ~/Library/Preferences/
2. Delete (drag the file to the trash) the following files: com.apple.softwareupdate.plist , com.apple.preferences.softwareupdate.plist (if you have them both)
3. Reboot normally
4. If the notification is still there try
5. Going into Software Preferences > Software Update , it said the same "Your Mac is up to date -- macOS Catalina 10.15.4" and then the badge should disappear!
6. Automatic updates are still enabled and the badge should not come back.

Answer 2

Run in terminal:

defaults write com.apple.appstored LastUpdateNotification -date "2029-12-12 12:00:00 +0000"

It hides the notification until the end of 2029. You can use any future date here.
