Okay, the Time Machine / AirPort Extreme situation is now officially ridiculous. TidBITS's Glenn Fleishmann says Apple's confirmed to him that the Extreme is unsupported for use with Time Machine, even though the latest batch of updates enable AirPort Disks to show up in the Time Machine disk-selection box. Fleishmann thinks a it's leftover developer testing glitch, but either way, Apple's will-they-won't-they routine means lots of people now have an unsupported backup solution that works "erratically." Seriously, if you thought AirPort Extreme owners were pissed off about Time Capsule, just wait until backups start failing. Not a lot of options left, Apple -- better get this feature up and running ASAP.
