Has anyone else done an update recently and had it render the ports on the back of their TB display useless? There isn't a great deal of detail anywhere on what causes it. All I know is I did updates yesterday without paying too much attention to what they specifically were, and then on restart my peripherals and drives were dead.

I read it might be something to do with the update to support a TB gig-E adapter, but I won't be installing it again to test it.

The only fix is to flatten the drive and start again, or as I did by accident, install Snow Leopard on a separate partition and update that. It seems to have a knock on effect at the firmware level as after I did this as part of my testing it works in Lion now too.
 
That's the thing, I think there was a Thunderbolt firmware update as well as a supplemental update for 10.7.4 but I didnt check the details. I think they have been waiting there for a while as I dont jump on updates straight away for this exact reason, but hadn't heard anything bad.

Weirdly, the issue seems to occur on 2 separate MacBook Pros on 10.7.4 but I'm typing this right now on my own system in the Snow Leopard partition and everything seems to be working, as about 10 minutes ago the issue just suddenly re-appeared. So what I thought was a solution actually didnt work.

Going to try the zero/erase/reinstall tonight and see how that goes...
 
Just to update and then close this...took it into the Apple Store after lots of failed testing, and apparently the display was so ashamed of itself it didn't even power on for them.

Still waiting for the "Genius" to tell me its been fixed. They wont replace it there and then but they'll literally order every single part for it because they can't diagnose the issue.

Anyway, mystery solved...hopefully!
