If you have the space you could just download the installer but not actually do the install. Just having the installer in the Applications folder should be enough to keep the notification from showing up. There was another thread in the forums where one user had trimmed down the installer for, I believe it was Monterey, to just those components of the package that were needed to keep the notification from popping up. I don't happen to have a link at hand.
That was a slightly different problem, the Monterey installer kept downloading itself, sometimes even for people that were running Monterey.
In Big Sur now, I see Ventura in Software Update, but it doesn’t display a notification and, so far, it didn’t download itself.
If you have trouble ignoring that "Red Badge of Pain", copy this;
defaults write com.apple.systempreferences AttentionPrefBundleIDs 0 && killall Dock
Then run it in terminal but be sure to copy it to a simple text file, and keep that file in an easily accessible place. It will get rid of the red badge for a while (it will come back).
It’s easier if you save it in a command file:
Code:
#!/bin/zsh
defaults delete com.apple.systempreferences AttentionPrefBundleIDs
defaults delete com.apple.systempreferences DidShowPrefBundleIDs
killall Dock
The notification will be displayed again when Software Update or the user will search for software updates.
Not my experience. Never upgraded to Catalina so waited close to a year.
You can wait 100 years, the installation is not happening without your consent.
The point of the profile with Defer Major OS Software Updates is to not show the upgrade to Ventura in Software Update and the notification, but continue to display updates and notifications for Monterey.
