Q: Thunderbolt Display Firmware Update could not complete

Is anybody else having an issue applying this update?  I keep getting the following error:

I've tried turning off my computer and unplugging the display multiple times, but the update always fails and System Information still lists the Firmware Version for the display as 22.2.

Apple Thunderbolt Display, OS X Yosemite (10.10)

    i got the error twice, but checking system profiler it reported the correct firmware versions for both of my thunderbolt displays.... and then the 3rd time  i checked, software update showed it completed...... but im still having the issue where my display flashes black for a second. irritating for a pair of 900 dollar (or whatever they cost) displays.

    Same.

     

    I have three thunderbolt displays connected to a Mac Pro. I got the error message, then read that no more than two displays could be connected during the update. I disconnected one of them and restarted. Then connected the other and disconnected the first and restarted again.

     

    I'm not sure any of that worked and have no "active" notification that they were updated. I checked the firmware version following that update per the instructions and they match the version, but I'm still getting the random flicker.

    I fixed that blackout issue by turning of the option "Automatically adjust brightness" in display preference. No more blackouts for weeks.

    II had the same problem. Apple states that

    • If you’re using a MacBook Air or MacBook Pro to run the update, the lid of needs to be open. "Closed clamshell" mode will not allow the update to install.

    I was in clamshell mode. Did it with my Macbook Air open and everything went well.

    Hope this helps.

    I've done this a few times with my Macbook Air open, with no success.

    Same issue.  The update request recurs periodically but does not complete.

    I have a similar issue.  I have a new Thunderbolt Display connected to a late 2013 Mac Pro.  When this problem first appeared, I contacted Apple Support and was helped with installing the update to the latest version; however, the update continues to appear every couple of days.  If I try to install it, I get the same error message but it then shows as installed.  Lo and behold, two days later it shows up again.  There is a flaw here that Apple has not seen worthy of correcting.

    So what's the fix here for this, because every time I leave my macbook pro connected to the thunderbolt display, as soon as it goes to sleep the system crashes and I have to restart everything again

    After installing Thunderbolt Display Firmware update 1.2, while in clamshell mode, I kept on getting the popup message during login.

    "Thunderbolt Display Firmware Update could not complete"

     

    The only way to get rid of that was to cleanup directory "/System/Library/CoreServices/Firmware Updates", using Disk Target Mode...

    Was not able to remove files as root, nor in SUM.

    Not sure which folder exactly was causing the popups...

     

    Use at your own risk

     

    I hope that helps

    Same here - fails to install, and never shows up again under Updates in Software Updates.

     

    I checked and I do NOT have the correct firmware or micro port firmware.

     

    It keeps complaining that it failed to install, but there is no option to install it from within Software Updates.

     

    Is there a direct link to this update somewhere?
