   Mac Pro SMC Firmware Update 2.0

   Agen G. N. Schmitz

   Apple has released [1]Mac Pro SMC Firmware Update 2.0 for Mac Pro
   models released at the end of 2013. The System Management Controller
   (SMC) update enables most Power Nap activities to proceed without
   running the Mac Pro's fan, and it fixes a rare problem that prevented
   low-speed USB devices from being detected after booting up. As always,
   be careful not to interrupt the update process when applying a firmware
   update. (Free, 585 KB)
