Security Update 10.14.6 will not complete.
My computer is stuck on the Security Update 10.14.6. I have reinstalled from a Time Machine back up and tried downloading the security update from Apple Support directly, but for some reason this attempt is stuck and cannot unstick itself.
I want to download Mac OS Catalina, but this is stopping me because when I go to check for new updates, it appears I need to finish downloading Security Update 10.14.6.
This has been stuck on my computer since November 11.
MacBook Pro 15", macOS 10.14
