If you are one of the owner of this sexy slim Macbook Air, i am telling its time to update your software. Apple has recently released a patch “MacBook Air Update”, no less – designed to address “issues with video playback and processor core idling.”

You can get it updated via the Software Update functionality built into MacOS X, or from Apple’s website, it seems like a must-have update the fact that the CPU cores don’t reduce their power usage as much as they should while idle.

This leads to decreased battery life and increased heat output, but if you’re running any third-party apps you should uninstall them before running the update. That’s uninstall, not just disable.
