MacBook Air SMC Updates 1.5 and 1.6

Apple has issued two System Management Controller (SMC) updates for the MacBook Air — version 1.5 for models released in June 2012 and version 1.6 for models released in 2011. Both updates enable Power Nap support when running OS X 10.8 Mountain Lion, while the version 1.5 update for mid-2012 MacBook Air models also fixes several sleep and wake issues that should improve overall stability. Version 1.6 (for mid-2011 models) requires 10.8, while version 1.5 (for mid-2012 models) requires 10.7.4 or later. To ensure you get the firmware update for your specific model, we recommend relying on Software Update. (Free, 698 KB/663 KB)
