This update will not complete upon restart and results in the prohibitory symbol.

Security Update 2019-006 10.13.6 will not complete after restarting computer. When it restarts, the prohibitory symbol appears. I choose the Installer disk presumably to complete the install, then I log in, only to find the prohibitory symbol again. If I choose the regular disk I am back to square one on downloading the update. Any thoughts?

MacBook Pro 13", macOS 10.13

Try downloading directly & installing it in Safe Mode...

Safe Boot from the HD, (holding Shift key down at startup), does the problem occur in Safe Mode?
