Any ideas on how to debug or fix this would be appreciated.

2 suggestions: one fairly easy, one less so.

#1

I have an Apple 27" Thunderbolt display on my Retina iMac. I have to
use
a separate external Thunderbolt cable, *not* the built-in one.

The built-in captive cable works, but then the auxiliary ports on the
back of the screen do not and both adaptive brightness control and
direct control via System Preferences fail.

So, try a different cable.

Looking for a replacement cable lead me an article that says that
removing the cable is only possible by disassembling the display [1].
Was that what you had to do? The cable does not seem user-removable at
my end.


#2

I know it's not very helpful, but I'd try with a different OS, e.g.
Windows.

I have failed to get my device working with another non-Apple
computer,
and Googling for why suggested it probably won't work with anything
else.

That's also possibility. I probably should've tested before quickly
wiping Windows ... I was encourage by the fact that there were many
references to this display working on Linux.

Might be the thunderbolt 3-to-2 adapter I'm using, as referenced at

But unfortunately I would not have the time to install Windows on my laptop.

Thanks,

Robert
