This update was disgraceful. Shame on Apple. I encountered one side effect that wasn't mentioned in this excellent article: the root password stopped working after I installed the update. Because I was using root as my admin account, I was unable to do anything that required admin authorization. I called Apple Support and they were no help. Their only recommendation was that I erase my SSD and install a fresh copy of macOS. Ouch.
