Apple has released MacBook Air EFI Firmware Update 2.9 for MacBook Air models released in mid-2011. Ostensibly, the update addresses two issues related to waking from sleep — a bug that prevented waking in a timely maner and a problem that caused fans to run at full speed after waking. However, there are multiple reports on a discussion thread at Apple Support Communities that installation of the firmware update is causing some MacBook Air laptops to shut down completely and not start up again for a lengthy amount of time (so much for that timely waking fix). Additionally, other users report still seeing the EFI update in the Mac App Store’s Update section even after applying the firmware multiple times. This might be one to wait on for a few days to see if Apple reissues EFI Firmware Update 2.9. (Free, 4.1 MB, 10.9.2+)
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.

Giving me a nice warm and fuzzy apple feelling!
All is well after a full shutdown and restart but there is/was no FW update :-(
I didn't really need that near heart attack.
