Q: 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?
MacBook Pro with Retina display, OS X Yosemite (10.10), Thunderbolt Display 27"

My first firmware update failed. Is it connected to a MacBook Pro?? Open the lid so that the progress bar can display during install. That worked for me.
What failed for me was the restart did not seem to get the display audio recognized.... I was left with only Macbook internal sound in Sound Preferences. Stupidly, I did not reboot and simply called support. He suggested a restart and that brought back sound from the display and the microhone in the display could be used in Skype. BUT, iTunes still had no sound at all. It was open during the restart. I closed iTunes and toggled the sound preferences to get the display sound back.
Hope this helped.
