Apple has a released a new update for the MacBook Air, specifically addressing the notebook's Bluetooth wireless technology. Unlike most updates from Apple, there is no information on what the new one improves or fixes; the company will only say that it "should be installed on all MacBook Air Systems." The patch is a 1.2MB download, and requires Mac OS X 10.5.1 or higher; it can be downloaded automatically through Software Update, or installed manually following a web download.
