So, if you installed OSX Beta or GoldMaster versions, your account enrolled for pre-release updates.
Now, you installed OSX El Capitan from app store (final release, 10.11) but in AppStore -> Updates, Developer Beta keeps whowing you to update to version 10.11.1. This is because your account has now enrolled to pre-release updates.
To fix this, go to System Preferences -> AppStore
You can see there is a setting called “Your computer is set to receive pre-release Software Update seeds”.
Click “Change” and then “Do not show pre-release Updates”.
Done. You can now refresh the Updates tab in AppStore.
Everything is clean.
