Firmware for Thunderbolt Display can not be complete.
Monitor Thunderbolt Display 27 2014 does not recognize either the keyboard or the sound entrance.
AppsStore tells I have to update Firmware 1.2 for Thunderbolt Display, but at the end of the installation I get that message:
Firmware for Thunderbolt Display can not be complete.
'No se ha podido completar la Actualización de Firmware para Thunderbolt Display’ (in Spanish).
