Can't opt out of Beta downloads I opted out of beta downloads under System Preferences > App Store, but I still see macOS beta downloads in the Mac App Store.

How can I fix this? Caching issue?

Once you've unenrolled, run this command in the terminal:

sudo softwareupdate --clear-catalog


This worked for me!
