Apple Releases MacBook Air Update
Apple released an update for the MacBook Air aptly named "MacBook Air Update 1.0" on Friday August 22, 2008. This is to resolve a longstanding issue with processor idling. The reported issue in the Apple Support Forum is actually one in which one of the two Core 2 Duo processors would shut down when it got too hot. This greatly affected the system's responsiveness while while waiting the processor to cool.
The release notes from Apple: "This update is recommended for all MacBook Air computers, and addresses issues with video playback and processor core idling. Third-party software that modifies processor operating characteristics such as frequency and voltage is not supported and should be removed before installing this update."
