Afternoon all, hope you're all well as can be expected.
Has anyone seen this, or know what I can do about it? High Sierra online update didn't finish, something must have buggered the internet connection and I now have one very unresponsive Mini, early 2014 model. It tries to boot 5 times with the code, then puts up the circle and that's my lot.

Dare I say - wipe the disk and restore from backup?

Does holding down the option key on startup give you any useful options?

Hi Leewave, apart from the previous two days stuff is backed up on the old 2007 Mini I'm using at the moment so not too bad.
Anndra, there's isn't even a chime at boot up so the option key does nothing.
I've got Tiger 10.4 so I'll try that once I've got hold of an external drive that works. I was hoping for some way of completing the update online, but that looks like a dead duck.

I don't think 10.4 & 10.13 can run on the same Mac?

Don't see much choice but to attempt a system downgrade.

Shouldn't be a problem with a second Mac and TDM or if you still have a recovery partition that you can boot into - but then with a change of file system on the HD to APFS I don't know if that messes things up. This change of file system and still in the proto-beta stage too, probably throws a bit of a spanner in the works. But all do you need to do is to wipe the disk completely, re-partition into one with HFS+ and start again.

Ta for the suggestions, seems to be solved now simply enough though still a bit of nervy process updating online. Holding Option-Command-R during startup took me to a box of choices, chose install system, was presented with a spinning picture of Earth and after a bloody long time the Mini is running again with the High Sierra update and all files intact.

Flippin' hate this App Store business, one little hiccup on the 'phone line and yer buggered.

Absolutely. Totally unrealistic strategy from Apple for the millions of us WITHOUT decent Internet speeds or reliability. I cannot even contemplate such an update with an Internet speed of about 0.9Mbps - and a couple of bl**dy Windows10 PCs on the same router, also trying the same online-mega-update trick every now and then.
