Apple updates Time Machine
Apple today released a combination update for Time Machine, bundling with it Airport driver fixes. What the update actually fixes is unclear, simply stating "This update is recommended for all users and includes compatibility improvements for using Time Machine with Time Capsule, as well as AirPort driver fixes." The update is available through Software Update under the Apple menu, but Apple has not released its typical accompanying web pages on its support site.
Update: Apple has made an appropriate page for the download.
