Apple has released Mac Pro EFI Firmware Update 2.0 for the lucky few who have received their shiny new Mac Pro models (see “Mac Pro Available to Order, Shipping in February 2014,” 20 December 2013). This firmware update improves system reliability during reboot, resolves an issue with memory self-test, and improves graphics power management when using Boot Camp. As always, be careful not to interrupt the update process when applying a firmware update. (Free, 4.7 MB)

Press Control-Shift-Eject and your monitor sleeps without engaging the screen saver.
