   MacBook Air SMC Update 2.0

   Agen G. N. Schmitz

   Apple has released [1]MacBook Air SMC Update 2.0, the second
   consecutive SMC update to address battery issues (see '[2]SMC Firmware
   Updates for MacBook Pro, MacBook Pro Retina, and MacBook Air,' 3
   October 2013). Directed at MacBook Air models released in the middle of
   2013, Update 2.0 fixes a problem that caused the battery to drain more
   quickly than expected with the lid closed. As always with firmware
   updates, we recommend relying on Software Update or the App Store app
   to ensure you get the firmware update for your MacBook Air, and being
   careful not to interrupt the update process. (Free, 804 KB, 10.8.5+)
