Thunderbolt Display Firmware Update 1.2

I have a MacBook Pro (Retina, 15-inch, Mid 2014) and two thunderbolt displays. I recently started getting notified there was an update available, Thunderbolt Display Firmware Update 1.2 and App Store kept prompting me to download and install.
I tried multiple times, and each time it states it failed to update. According to this KB article About Thunderbolt Display Firmware Update 1.2 - Apple Support it states Firmware Version should be 26.2 and the Port Micro Firmware Version should be 2.0.7 after the update.
I checked and my Mac is in fact reporting the updates were applied. See information from the system report below. I am prompted every day, multiple times to download and apply this update again, over and over. I don't understand why.
I contacted Apple Support and the rep I worked with was pretty much useless. In fact, I am fairly sure I know more and *NIX than he does. Anyway, does anyone have a suggestion on howe to remedy this?

Strange. The downloaded dmg file package said that the upgrade was successfully installed, but the App Store still says I need to update. I haven't tried it with my MBP cover open but I'll give that a shot.
Thanks,

  • Thunderbolt display firmware update 1.2 won't install correctly

    On Friday 11/13/2014, I received a Software Update notification in OS X Yosemite 10.10.1 that there was an update available for "Thunderbolt Display Firmware Update 1.2". I tried installing this several times, but every time it tells me "The Thunderbolt Display Firmware Update could not complete." Now I have 6 failed install attempts showing in Software Update, plus still the still to be installed update itself.  
    If I click on the "More info" button in the failed installation message, it takes me to this page: About Thunderbolt Display Firmware Update 1.2 - Apple Support
    On that page it suggest to check the "About this Mac" info for Thunderbolt Display, where "The Firmware Version should be 26.2 and the Port Micro Firmware Version should be 2.0.7 after the update." 
    My Thunderbolt Display is currently on Firmware Version 22.2, with Port Micro Firmware Version 0.0.21. Why won't this update install?

    I had a similar problem: The "Thunderbolt display firmware update 1.2" kept reappearing in AppStore, even though the uppdate seemed successful.
    According to Apple[1] the update was successful when the the Firmware Version is 26.2 and the Port Micro Firmware Version is 2.0.7 (visible in About this Mac -> SystemReport).
    Above versions were correct in my case, but the update still kept appering in AppStore... (probably I did download and install the update manually after the first failure, but I don't remember ...)
    To get rid of the annoying update in AppStore I used the softwareupdate command[2] on the commandline:
        softwareupdate --ignore TBdisplayFWUpdate1.2
      [1]: https://support.apple.com/en-us/HT204450

  • Thunderbolt Display firmware update 1.2 failed

    Thunderbolt Display firmware update 1.2 fails to complete.  I have made four attempts to load this software update.  The odd thing is that the software list shows that the update has been installed.  But every time I check for updates, Thunderbolt Display firmware 1.2 is listed as a needed update. 

    Strange. The downloaded dmg file package said that the upgrade was successfully installed, but the App Store still says I need to update. I haven't tried it with my MBP cover open but I'll give that a shot.

  • Thunderbolt display firmware 1.2 install error not "connected directly"

    I have tried with 2 macs today to install the Thunderbolt display firmware update 1.2. My firmware is old (22.2) and I have had display problems since Mavericks (now with Yosemite too), so I would really like to try the new firmware.
    With the TB Display directly connected with a single TB cable to a mac mini or alternately directly connected to my MB Pro I get the error:
    I have tried to use both software update and a downloaded version of the Firmware update. Both have the same error message issue on both of my computers. Also, software update keeps showing the firmware as a recommended update after the failed installations.
    Does anyone know a fix to this?
    Thanks

    Solution:
    As I proofread my post, I realized I did not note the part about the "built-in" cable and only focused on the "connected directly" part of the error.
    Using the built-in Thunderbolt cable I was able to successfully install the firmware.
    If anyone else makes this dumb mistake, maybe this post will help you not feel too bad!

  • Thunderbolt Display Firmware 1.2 / 10.10.1 Update device connected but no display

    I looked through a lot of the Thunderbolt Display Firmware 1.2 posts about the display not functioning but never saw one with circumstances quite like mine. In my case, I updated the firmware and the display continued working until I had to reboot for the 10.10.1 system update. After the reboot, my display stopped displaying.
    The display wasn't completely non-functional. The symptoms I saw were:
    The Displays system preference only showed one display available (my rMBP)
    The System Report under About This Mac showed my Thunderbolt Display was connected
    The keyboard connected through the Thunderbolt Display worked properly
    Just no display at all. First I tried a simple reboot with no success. Then I tried a PRAM reset (3x) again with no success. Finally I disconnected all Thunderbolt connections from my rMBP and did an SMC reset. After booting back up I reconnected the display and boom back in business!
    Hope this helps someone.

  • HT6093 the new thunderbolt display firmware NOW makes my screen go black all the time!!!  how can I uninstall this last update?

    the new firmware for the thunderbolt display now is making the screen go black all the time.  _the fix created the problem!!!
    how do I uninstall this update?

    You can't.  There is a long discussion in the Thunderbolt forum.  Look there.

  • HT6093 Updating two Thunderbolt display firmwares

    I have two Thunderbolt displays, one at work and one at home. I updated the firmware of the work one, and want to update the firmware of the home one.
    With the Macbook Air clamshell open and the display plugged in, the App Store at home says that the update has already been applied.
    Suggestions?

    Yes, the firmware is the old firmware, because the update never ran on the home display.

  • No sound from Thunderbolt Display after update to OS X 10.9.3

    So I updated to 10.9.3 this morning only to find there is no sound coming from my Thunderbolt Display after installation. Sound is now only audible from my MacBook Pro (late 2011). Also, see image below, there is no sign of any connected inputs other than my MBP now. I've shutdown and restarted a number of times, but still no audio from the display.
    Really starting to wonder why it's worth spending so much on Apple products now...

    I sent my TB Display in for repair. They had it almost a week and didn't find anything wrong with it. Instead they took in my MacBook Pro and replaced the logic board (2nd time it had been replaced) and the Display seems to be working fine now.
    ...except that for using 3rd party video conf apps, those apps only pick up the MBP camera (even though i try to change settings in app), not the TBD camera... but FaceTime and Skype find the TBD camera.
    Strange.

    I completely agree with that sentiment. That's why we pay through the nose for their products, so it feels very bad when they don't just work.

  • Fix for Thunderbolt OTA firmware update , when receiving an error message

    Hi, my name is Lou, and I'm not sure if this is the right place to post a solution or fix for Thunderbolt users that are unable to get their firmware update OTA..
    For the last 2 weeks, when i got word that the (OTA) Over The Air firmware update should be coming out, i started going on my phones setting to check for new updates and started to receive an Error message, stating to check back when service was available, well Verizons attempt at fixing the issue was to to a hard factory reset, which didn't work, they also had me go to the local Verizon Wireless store and switch out my SIM card, and that didnt work, and they also tried Forcing the update to y phone, and again No resolve.. There last solution was to send me a refurbished phone, which I am strongly against, cuz I dont want a used piece of equipment, ... well anyways, I found the solution for the fix of getting the update downloaded to your phone, from www.thunderboltforums.com ,
    You first need to downlaod an app from the market titled LTE On/Off app, install it. Once installed, I turned of my WiFi on the phone, then opened the LTE On/Off app, and rememer the original setting that its on, bcuz thats the setting u will have to set it at, when your update begins...   Select the CDMA mode, not the CDMA(PRL) mode...  then exit the app.... By selecting the CDMA mode only, this should make your either 3G or 4G signal switch to a 1X symbol.. then, i restarted my phone, .... i dont think restarting is necessary, but i did it anyways... when it restarted, the signal setting was still at 1X, then I went to setting, aSoftware Update, then Check Now, and within a minute or so, the Download option appeared.  once I started the downlaod, I let about a minute pass by, then I went and opened one last time, the LTE On/Off app, and switched the setting to its default setting, and mine was the 4G option and the 4G signal kicked in, and the 78Mb download completed within 3 minutes...  hopes this helps... It helped me...

    I could be wrong but I believe this has been covered but thanks for sharing still...

  • 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.

    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.

  • Canceling Cinema Display Firmware Update

    I accidentally selected to update the Cinema Display iSight from the Software Update list but I do not own a Cinema Display. Now every time I start my computer up I get a prompt asking me to connect to a Cinema Display so I can update it's firmware. How do I get this to stop trying to complete the update?

  • When will the thunderbolt display be updated with usb 3.0

    Eagerly awaiting this update -- will buy as soon as it's available.

    No one knows... but I would imagine that when a new ATD is released, it will have USB 3.0 ports.

  • Thunderbolt Display USB ports not working after 1.2 firmware update

    I installed the Thunderbolt Display Firmware Update 1.2 a few days back, and following that update, the USB ports on my display have stopped working completely. The display's Thunderbolt port and Ethernet jacks are working fine, as is the Thunderbolt/power cable connection to my MacBook Air (mid-2011, 11 inch, running OS X Yosemite 10.10.1). Any ideas on a fix?

    Do an SMC and PRAM reset.

  • Can't stop Thunderbolt display from flickering white lines after firmware update (Yosemite)

    I am having serious issues after the Thunderbolt Display Firmware Update 1.2. Running Yosemite on MacBook Pro and I am now getting white lines that gradiate from the bottom to the top of my screen across multiple browsers, apps and even the finder window anytime I move my mouse. I cannot take a screenshot (it stops when I try) but I posted a video here:
    http://youtu.be/3zOKL1JFp5M
    It is impossible to work this way and after 20 minutes of watching my screen constantly refresh anytime I move my mouse I am feeling nauseous.
    Is there anyway to UNINSTALL this firmware update? I was not having this kind of problem before. Every once in awhile I was finding my Thunderbolt display would not wake up after sleep and I thought the firmware update would fix that, not cause more, crazier problems. It is causing this gradiating line problem on my Thunderbolt display AND my MacBook Pro screen, which is even more bizarre.

    I updated and no issues with my 2012 Mini so may be computer related.  I believe once a firmware has been "burned" into the chip it cannot be redone.

  • Thunderbolt Display "dead" after firmware upgrade to Version 1.2

    Hi,
    I just run the Thunderbolt F/W update to 1.2 as offered by the AppStore Update. I have a 2014 MacPro with 2 Displays connected. In good faith I just confirmed to apply the update without much reading the fine print. The F/W update brought the system to a complete standstill. After 2 hours of waiting in the boot screen, I rebooted the system manually (5 secs power button). One of the Thunderbolt displays first just flickered, then decided to completely die. The System report says: unknown device in the Thunderbolt section. The 2nd display hasn't been updated during this procedure.
    How can the F/W of the 'dead' display be re-installed? I also tried to connect it to a MacBook pro. Same result. The display is entirely black.
    Any help or suggestion is much appreciated. Thanks!

    Put me on the list as well.
    I've had this TB display for two years and have had no issue with it. Clicked OK on the firmware prompt and now I have a $1000 paperweight/laptop charger.
    What I have tried:
    Reset SMC and NVRAM on my MBP.
    Unplugged the display from power and all peripherals and let it sit for ~24 hours before trying again.
    Downloaded the firmware installer from Thunderbolt Display Firmware Update v1.2. It tells me that no thunderbolt display is connected.
    So far nothing has produced a result.
    System report shows an unknown device on the TB port.
    A used logic board for the display is around USD$220 on ebay.
    I really wish I had not attempted to install the firmware now.
