Can't stop showing macOS public beta update in Mac App Store
I occur some serious problems in macOS Sierra 10.12.1 beta: https://forums.developer.apple.com/message/183219but nobody in Apple care about that, so said, so I have to restore my mac to macOS Sierra 10.12 (thanks to I have a backup before...).
Now my system version is macOS Sierra 10.12 ( please do not delete this post, it's not a beta version, thanks).
My problem:
I have already changed "Your computer is set to receive pre-release Software Update seeds" in App Store Preferences to "Do Not Show Pre-release Updates", but I still receive the 10.12.1 public beta 2 1.
I'm afraid to upgrade to 10.12.1 beta again, what will carry some serious problems before.
Anything I missed for Opt out of updating to any macOS beta version.
