   Thunderbolt Firmware Update v1.1

   Agen G. N. Schmitz

   Apple has released [1]Thunderbolt Firmware Update v1.1, which addresses
   a problem with the MacBook Pro that was released in June 2012 (as well
   as some Thunderbolt cables) that prevented some bus-powered Thunderbolt
   devices from working as expected. The update requires Mac OS X Lion
   10.7.4 or later. (Free, 442 KB)
