MacBook Pro Retina Display And MacBook Air Battery Issues Fixed With Update
Apple has issued an update for MacBook Pro retina display and MacBook Air users that fixes a battery bug that causes battery life to drain faster than it should. The update is available via the Mac App Store.
This update is recommended for MacBook Air (mid 2012 and mid 2013) models. This update addresses rare issues where the battery unexpectedly stops functioning, the system does not recognize the battery, or the system hangs when the battery charge reaches less than one percent.
