Tried everything I can think of - ran Disk Utility First Aid in Recovery Mode, tried installing via Safe Mode, tried installing from Terminal, etc.
Nothing seems to work - this update just will not install. It acts like it does, but after reboot, the same versions of MacOS and Safari are still there and the Supp Update doesn't appear in Installed Updates and *sometimes* reappears when checking for new updates.
Frustrating, to say the least...
