My MacBppk Pro will not accept the security update 2020-006. Each time I think the update has completed, the reminder that there is an update waiting pops up. What can I do to download this security update?

You haven't told which OS you are running, that might help in identifying which 2020-006 Security Update you are talking about.

Years of being on these communities has taught me that just because someone is posting in a particular OS community is no

guarantee that is the OS they are on.


Have you tried to download it via Apple Support Downloads.


There were two 2020-006 Security Updates one for macOS High Sierra and one for macOS Mojave.

Download the one for the OS you are running, once downloaded double-click to install.
