Small Mac, iOS releases
(Updated with iOS AirPort, OS X Mavericks updates) Apple has posted a small update for the Mac version of AirPort Utility, v6.3.1. The patch deals with a single bug that prevented AirPort base stations from being detected. The file is a 21.6MB download, and available either through Apple's support site or OS X's Software Update feature.
Update: The iOS version of AirPort Utility has been updated with the same correction. Separately, the OS X Mavericks developer preview has been issued an update to its Recovery mode. It's unclear what exactly the code fixes, but it's available through Software Update.
