Late 2012 Mini - 10.13.4 updates not installed

My Late 2012 Mac Mini 6,2 16GB with 1TB Fusion drive refuses to upgrade from 10.13.3 to 10.13.4 reporting "Some updates were not installed. Details/Install".

I have tried:

1) App Store Upgrade

2) Update Combo 10.13.4

3) Booted to recovery mode, ran disk repair which found and repaired errors, rebooted, then Update Combo

4) Booted to safe mode, ran Update Combo

I checked logs but do not know what is significant.

Any ideas what else to try?

Mac mini, macOS High Sierra (10.13.3), Late 2012, 2.6GHz Core i7 16GB

I worked with Apple support to file with the developers, and the result came back: no idea how the update corrupted your fusion drive. Only solution is to erase fusion drive, install 10.13.4 and then restore apps and data using the migration assistant.

This is not for the light hearted, but it worked. See http://www.wiredbob.com/2013/12/clean-installation-of-fusion-drive.htmlhttp://

(The secret to success was booting from my MtnLion8.3ESD USB stick, deleting the fusion drive, then re-creating the "Macintosh HD" fusion drive. *and* the magic of Time Machine/Migration Assistant. )
