Can't Shutdown or Restart After Attempting 10.13.3 Supplemental Update

After attempting to install the 10.13.3 Supplemental Update from the App Store, my mid-2010 MacBook Pro will no longer Restart, Shutdown, or Sleep from the Finder menu or logon screen. Instead, I get a black screen with the cursor in the upper left hand corner when I shutdown or restart. The only way to shutdown my Mac is to hold down the power button. The problem seemed to originate after the 10.13.3 Supplemental update requested a restart.

The problem remains even after I reset the PRAM, SMC, rebuilt the LaunchServices database, and did two clean installs of OSX using Command-R when starting my Mac. After re-installing OSX, the App Store still indicates that I need to install the 10.13.3 Supplemental update.

Using Terminal, I can perform a clean shutdown and restart using the commands "sudo shutdown -h now" and "sudo shutdown -r now".

Has anyone else experienced this issue and have a solution?
