Jan 2022 Apple Security Update bricking display again

[OAG]

New Mojave Security Update Jan 2022 has done it again.

All S1 Displays Full Yellow.

[Frank Kruse]

Are you sure? I thought they fixed this in the current version. Your EC 21.6 won't have that fix.

You're quite correct Frank. Thank you.

I believe I had a patched 2021.6 which fixed the last yellow brick road, but obviously not this one.

I missed 2021.10, I think because it was all working fine and I didn't need the new stuff. Eucon was working really well (after a very bad start - ended up with a dedicated WiFi/ethernet router straight off the Mac Pro as everything was always falling off).

So I've gone up to 2021.10 now including all firmware and control updates and I have the displays back on the S1 tablet.

I can't, however, get my Dock tablet to add to Eucon.
Which is a bit of a concern. And a lot worse than some yellow blocks.
But I'll see what I can do with some coaxing..
