10.13.2 supplemental update hangs on Installation is in Progress

Just ran the newly released 10.13.2 supplemental update. Installed fine on my MacBook Pro. On my Mac mini (latest model), however, the computer is hung up at about 66% progress with the message "Installation is in progress. Calculating time remaining..." status. With much hesitation I tried a hard reset after almost an hour of waiting. Upon restart it hangs at the same spot. Any ideas? I'm currently out of commission so any help would be much appreciated!

Reinstall El Capitan or Later Without Erasing Drive

Please be sure you back up.

Restart the computer. Immediately after the chime hold down the Command and R keys until the Utility Menu appears.
Select Disk Utility and click on the Continue button.
Select the indented (usually, Macintosh HD) volume entry from the side list.
Click on the First Aid icon in the toolbar. Wait until the Done button activates, then click on it.
Quit Disk Utility and return to the Utility Menu.
Select Reinstall OS X and click on the Continue button.

Apparently patience is the key...my mid-2006 MAC Mini took about an hour. No known repercussions from an impatient forced restart at the 10 minute mark.

Have faith in Apple.

45 minute install, mostly stuck on ‘calculating time remaining’ on a late 2012 iMac (fusion drive and 32 GB ram)
