Mac OS X 10.5.2: World of Warcraft Fix, Still No Airport Extreme Backups (Yet)
- The latest seed reportedly fixes a known driver problem that affects World of Warcraft on PowerPC machines.
- Despite early hope that the 10.5.2 update would fix Time Machine's Airport Extreme + USB (AirDisk) drive backup incompatibility, the latest Mac OS X developer seed does not appear to fully address this issue. While AirDisk drives can sometimes now show up in the newest Time Machine, backup attempts to them have been unsuccessful. While these reports are based on beta/developer versions of the software and admittedly limited testing, Apple lists "no known issues" in their seed notes for this latest version. It's also conceivable that an Airport Extreme firmware update may also be necessary as well to fully implement this feature.
Apple had originally advertised Airdisk wireless backups as a feature for Leopard, but this feature was removed prior to its launch. Speculation has suggested that it may have been due to some unresolved security issues, but Apple has made no official statements. While there have been workarounds published, the announcement of Time Capsule raised hopes again that Apple would address this issue soon.
Update: Babygotmac posts their findings on what happens when they do try to backup to an AirDisk.
