Thunderbolt Display, Firmware 26.2 and Micro Firmware 2.0.7; however, Apple USB keyboard goes inactive when display sleeps.
Is anyone still working on fixing the "Thunderbolt Display Firmware"? This current release has not fixed the problem when the Apple display. If the display goes to sleep it can make the Apple USB keyboard unusable. The wireless mouse can bring the display back but when you try to enter an account password to login. The keyboard has lost connectivity.
The only work around is to plug the keyboard directly into one of my limited number of usb ports on my laptop.
Please fix this problem for all 27 inch Thunderbolt Display's.
This is still not working as stated in About Thunderbolt Display Firmware Update 1.2 - Apple Support
