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)
Avoid Long Hierarchical Menus
If you right-click (or Control-click) on some item, such as a file in the Finder, and one of the sub-menus has many options (Open With is a frequent culprit), it may take several seconds to open, even on a fast machine, which is annoying if you did not actually want that sub-menu.
The trick is to not pull the cursor through the menu, but in a curve around it, so the cursor does not touch any menu items until lower on the list where you wanted to go.
