Updates 10.15.6 supplemental update won't install on my MacBook pro

I have updated this supplemental update for Catalina several times and it keeps stating it needs to be updated. How do I get this to update and the notification to update, to go away?


MacBook Pro 13″, macOS 10.15

Try a SafeBoot https://support.apple.com/en-us/HT201262

Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and run the update.
