How to update macOS to latest release of current version? I am on Catalina 10.15.3 and do not want to move to Big Sur just yet. Software Update does have the option to update to Big Sur but I am unable to determine how to do just a minor point update.  How do I install the latest update of Catalina?
Update From a comment by @jefe2000 I am trying the command line version and it seems promising.
$/usr/sbin/softwareupdate -l
Software Update Tool

Finding available software
Software Update found the following new or updated software:
* Label: macOS Catalina 10.15.7 Update- 
    Title: macOS Catalina 10.15.7 Update, Version:  , Size: 5099042K, Recommended: YES, Action: restart, 


But what is the actual label?  I was unable to get this to work and have created a separate question for it.  Unable to install an update via the softwareupdate command line tool
Download and install the Catalina 10.15.7 Combo Update from Apple.
