Thunderbolt Display "dead" after firmware upgrade to Version 1.2

I have late 2012 rMBP and TBD. Installed 10.10.1 and TBD FW 1.2 . Monitor is a brick now. So count me in.

See: Thunderbolt Display Firmware 1.2 broke the USB inside the display.

No solution yet. I have a call in w/ Apple Support later today. I recommend you all start calling them.

Symptoms are: TBD connected, Mac goes to sleep or hibernate...when it wakes, USB (including Audio) is inoperative. Unplug/plug TBD back into Mac, item restores.

SMC and PRAM resets do not work permanently...restarting Mac (whether MacBook, Mac Mini or MB Air) doesn't work permanently.

The audio card in the TB Display is a USB device. If you look in your system report you'll see that it's connected.

Here's another thing you can try...Start FaceTime...You'll notice your FaceTime camera doesn't work (in the display) either. It's USB also.

I would strike a guess that the USB driver got borked on the firmware update.

It is possible to connect a TB cable directly from the TBD port bypassing the built in cable but that is not the correct way to update.

Same issue. I have 2 Thunderbolt Displays connected to a 27" iMac- after attempting to update them with App Store update one of them is dead. I also tried it on my MBP- still dead. I have an appointment at the Apple store tomorrow to further trouble shoot.

@Rich of the North, that's a different issue. In our case the problem is the display is completely dead. When it's plugged in, it won't even show up as connected to the Mac.

Aha, wish I had more help for you.

If we all contact Apple and mention this forum link, we might have Apple understand they released buggy and damaging update.

If anyone gets Apple to fix it for free please let us know.

By my count there are 11 people on this thread so far who have the same exact issue- 1.2 Thunderbolt Display update failed and left monitor inoperable (black screen). Given the fact that it is Apple hardware that was damaged by Apple software, I would hope that they will step-up and fix or replace these units in short order.

I am going to swing by the Apple store in a few to see if they have heard of the issue. I have a Genius Bar appointment for tomorrow afternoon- if they haven't acknowledged this issue yet, they will then.

Exact same problem. Now I'm stuck with a 1000$ power cord for my 2014 MBPr. Update said it failed, retried, rebooted. Panel dead. No power coming out of the USB ports but power cord works. THIS *****. Seriously there had better be some response soon. This is unacceptable in every way. It's a 1000$ piece of hardware I use every day.

If I go to the System Info to check if the update succeeded it shows that nothing is connected to the Thunderbolt port. I've tried both ports, no joy.

Just got back from the Apple Store. They agreed it seemed like the firmware update was the culprit and are going to replace the logic board even though the unit is out of warranty. The fellow I was working with hadn't heard of this problem and I showed this thread to him, so hopefully it gets escalated. Right now it doesn't sound like it's on Apple's radar though.

Just for the record, add me to the list. Same issue with a Mac Pro a few months old and a Thunderbolt Display only a week old. I'm totally down in the middle of a project with no way to monitor and can't even get a phone appointment for over 24 hours. After being a patient and loyal customer for over 25 years, I'm really disappointed in Apple this time.

I will have a support call with Apple on 10.15 CET. I will post the response in this thread. Already packed my TBD in its original cardboard box. I'm using it every day and very disappointed Apple doesn't respond to this thread so far.The nearest Apple Store is 250 kilometers from where I live.....

You have to restart your computer on safe mode, after all the installation is done. The TB display is back on. But a normal restart is good to finish everything.

Just passed a long time on the chat support from Apple, they recommend that and it worked.

Unfortunately this didn't work for me. Just had a chat with Apple Support. The case isn't on their radar. I was told to take my TBD to the nearest Apple Store (...) or to the reseller I got it from in the first place and then apply for 'European consumer warranty'. I told the guy this is not wat I plan to do. Already I have pointed Apple to the existence of this thread and all the bricked TBD. I hope this will help. In the meantime I will put my TBD back in it's cardboard box....

Took my TBD to the Short Hills, NJ store. They said, "sorry, the FW upgrade must have exposed an existing HW issue, that will $200 and 5 days to fix"

I told them what I thought of them asking me for $200 for a problem their download caused. I also pointed at this thread and they scoffed. When I pointed out that this is an apple.com website, they told me "it's the public, anyone can say anything they want here, it means nothing to them".

So again, I told them of what I thought of them asking me for $200 and I walked out of the store with my brick.
