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)
Increase Boom Volume Quickly
If you're using Boom to increase the volume on your Mac, you can change the amount to which Boom increases the volume quickly in two ways. Either use the slider available from Boom's menu bar icon, or enable and set hotkeys (Command-Shift-+ and Command-Shift-- by default). Then, when you need that push to 11, more volume is available at the click of the mouse or tap of the keyboard.
