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

So, I've had problems with this working since it came out.

 

I'm running a MBP Retina, 10.0.1 Yosemite.

TB Display (TBD) is on FW 1.2.

 

Just figured out,

 

When the MBP sleeps, then wakes, the USB inside the TBD is dead...no more.

 

Here's the things that won't work:

 

Audio

The ports (USB) on the rear of the TBD.

The Display FaceTime Camera.

 

This also kills the ports on the MBP until the TBD is disconnected...then everything on the MBP is fine.

 

Reconnect TBD, it works fine too...until the MBP sleeps...then it dies.

 

Anyone know how to downgrade firmware?

 

I've also checked the system report, everything is showing "connected" ... and all the firmwares are current.

Thunderbolt Display (27-inch), OS X Yosemite (10.10)

    I got the same problem and I would add also that any youtube video will not work until you disconnect/reconnect the thunderbolt plug.

    I've also done SMC and PRAM resets.  I've unplugged the TB Display for a half hour...and I thought that fixed it.  Until later, when it started doing the same thing. 

     

    I think the YouTube isn't playing because it's not detecting a sound output...but I'm not really sure the mechanics of web video...

    Have you tried o boot in recovery mode with Option down? when I do that I don't have the choice anymore to choose the startup disk. I discovered that On most portables, a yosemite install will convert your hard drive or SSD into a core storage volume.  A core storage volume is used for things like fusion drives and more importantly file vault encryption. It seems that this core storage volume is the cause of the power loss in the TB display. I found out that

    It is possible to revert the CS volume back to a normal volume (if you haven't encrypted it yet). I did that and all the power problem in my thunderbolt display are gone!

     

    Run these 2 commands in a terminal.

     

    diskutil cs list

     

    and then

     

    diskutil coreStorage revert lvUUID

     

    where lvUUID is the last lvUUID reported by the previous Terminal command.

     

    Then restart for everything to get back to normal after you have run these commands in Terminal.

     

    Then also the recovery partition will show up again in the startup manager when you boot up with the option key.

    Man, I'd love to try this but I'm encrypted already.

    Has anyone else tried this? I can see all the usual options for startup disks when I reboot in recovery mode. led

     

    ETA Would there be any harm in trying this fix even though I can see the usual options for startup disks in Yosemite recovery mode? I'm not using filevault.

    Just noticed another weird dimension to this issue: the problem only occurs when my MBP goes to sleep with an external drive connected through the display's thunderbolt port.

     

    When I take out the thunderbolt device from the display and put it to sleep and wake it, sound, USB and camera all work as normal.

    Hi,

     

    I have exactly the same issue, except that I am using a LG 34UM95-P display connected via Thunderbolt. The problems seems more related to how Yosemite handles thunderbolt-displays with an external USB drive connected to the display.

    Interesting...

     

    Now, this morning, everything worked fine on wakeup...

     

    I have a Drobo Mini connected via Thunderbolt display...

     

    So, if i can get the USB inside the display to fail again, I'll try disconnecting the Drobo and see if that fixes it.

    The problems seems more related to how Yosemite handles thunderbolt-displays with an external USB drive connected to the display.

    Which is ironic given the 1.2 firmware update description in the App store says 'This update improves reliability when connecting devices to the Apple Thunderbolt Display'.

     

    As a side note, as well as the RAID disk, I'm also running an RGB display using a thunderbolt adapter, which I daisy chain off the second thunderbolt port on the RAID.

     

    The second display still works fine in this mode, but not when connected directly to the TBD thunderbolt port.

     

    The MBP doesn't recognise the second display when it's in the TBD's thunderbolt, but it does recognise it when it's plugged straight into the MBP, or daisy chained off the RAID.

    By the way, I tried @duedate's fix and it didn't work for me.

    There's the fix.  Unplugged my TB drive that was chained through the display...problem solved for now.  Will report back tomorrow.

    Unfortunately it's not a fix for me, as using the display's thunderbolt port is the only way I can run my RAID and the TBD at the same time.

    Did not fix...same problem/symptoms exist.

    Yeah, it's not a fix. It's just that the issue didn't occur when there were no peripherals plugged into the display.

     

    But today my display isn't waking from sleep at all. Think I'll have to take it in to be fixed. Guessing from stuff I've read on other threads that the logic board may need replacing. :-(
