After a few Software Updates from Apple earlier today, I was crossing my fingers. I don’t think that had anything to do with it, but Mac OS X finally supports Time Machine backups over WiFi to an external drive. When Time Machine was first announced, there was mention of this feature that lets use a hard drive connected to an AirPort Extreme Base Station over USB. Silly me, who bought both components in anticipation of Leopard only to have the rug yanked out from under me.It’s all good now though. The latest update just hit and I’ve got Barb’s iMac across the house now sending bits and bytes to the AEBS and 320 GB drive next to me. And I didn’t even have to take the DeLorean out of the garage for Time Machine use.
