Apple on Monday released a new system management controller (SMC) for its MacBook Air line of ultraportables, targeting an issues related to unexpected battery drain experienced by some mid-2013 models.
According to the brief release notes, Apple's MacBook Air SMC Update version 2.0 targets a power handling issue that appears to be limited to mid-2013 MacBook Air models.
Specifically, the update addresses an issue that "may cause the battery to drain faster than expected when the lid is closed." A number of threads on Apple's Support Communities forum attested to the battery drain problem, with one of the larger discussions suggesting the issue is OS-related.
Last October, Apple issued MacBook Air SMC Update version 1.9, which addressed a serious issue where the battery would unexpectedly stop functioning or would not be recognized by the system.
Apple's MacBook Air SMC update requires OS X Mavericks 10.9.2 or later, or OS X Mountain Lion 10.8.5 or later to run. The download comes in at 804KB and is available from Apple's support website.

What's the picture got to do with this?
And what's wrong with that guy's hand?
I have a 2013 13" MBA with Yosemite installed. Tried to run the SMC update, and I get the error "this update is already installed on your computer". I guess they prepackaged that into 10.10.
Clearly he's offering the air up to Zeus, so that lightening will restore power
I also have a 2013 MBA and have indeed noticed a slight power drain, especially recently. I thought it was because of the heavy workload I subject the laptop to, and a possible resultant damage to the battery. Fingers crossed the update fixes it and I'm just paranoid. I love this thing too much to be having battery issues!!
Yet they won't fix the damn finder.
