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!

Thanks all for the comments. After banging my head against the wall and multiple attempts to start in safe mode and restart the update, I finally decided to give even more patience a try. The install took 74 minutes on my Mac Mini 2014 (8GB RAM, Fusion HD). The Mac Book Pro took probably around 20 minutes. Not sure why such a big difference, perhaps it is the SSD vs Fusion drive.

Quite honestly, I don't know exactly how long it took.

Maybe the first attempt I aborted after about 20 minutes or so, and then on the second attempt after I restarted my iMac the progress bar immediately zoomed to where it left off.

I then decided to just to work on my laptop and after roughly 20-30 minutes I saw that the login screen had appeared on my iMac.

Like I said, roughly 45 minutes all together.

Yes could be an issue with the Fusion Drive. My late 2010 Macbook Air with an SSD installed the update without a hitch.

My mom has an old (2010 if I remember correctly) iMac with a standard HDD. She has not updated yet, but I'll probably do it tomorrow. If there are any issues I'll let everybody here know.

I just tried this update on my 2013 iMac before reading this thread. The update went about 75% like others say, I waited about an hour (because why would I wait longer? Regular software updates do not take this long) and I reluctantly restarted my machine. It booted up fine and when I checked the App Store it said the update was not installed. Safe to say, I’ll get the next update. It’s not worth losing all my work or my machine over or the time it would take to restore from time machine. I’m just surprised this thread goes back a month and a half with still no word from Apple? I can only imagine this is happening to employees as well.
