I unenrolled from macOS Big Sur beta program, however I am still getting the 11.0.1 "update is available" notification. I would like to remove this so that I upgrade directly to 11.0 when GM is released. I don't want to install 11.0.1. Is there a way to delete cached update data so I only get 11.0 when it's eventually released?
The following Terminal command will stop your Mac from accessing the software update catalog for Beta software:
sudo defaults delete /Library/Preferences/com.apple.SoftwareUpdate CatalogURL
You might need a restart, or relaunch of System Prefs and Command R to reload the Software Update pane at least.
