softwareupdate shows 2 updates for Command Line Tools - get rid of one entry
I found one way to get rid of the duplicate by executing: softwareupdate -i &quot;Command Line Tools for Xcode-12.0&quot;.
Now beta 5 is gone as well.

But how to get rid of entries I do not want there? &quot;System settings&quot; were nudging me once a day to install the beta.
