Apple has released 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 at boot. As always, be careful not to interrupt the update process when applying a firmware update. (Free, 585 KB)
