Leopard: Data loss, AirPort...

There is reportedly a major bug in Leopard's directory-moving code, which manifests in the Finder, that can lead to significant data loss if a destination volume (where a file is being moved) disappears while a move operation is in action. The bug is reported and described on Tom Karpik's blog, and involves a situation where a file is copied from one volume to another. A test setup by Karpik involves an SMB server and a MacBook Pro running VMWare. Essentially, the directory to be copied will be deleted if the destination is closed down in the middle of the process.

Meanwhile, Apple has documented an issue in Leopard where after installing the Login and Keychain Update 1.0, the computer's AirPort card may not work. Apple says the solution is to start up in Safe Mode by holding the Shift key during startup. Once the computer has started in Safe Mode, simply restart again (without holding any keys). On a related note, some manufacturers of wireless adapters for Macs are updating their software and drivers for Leopard compatibility. QuickerTek has updated its complete line of Quicky and nQuicky wireless signal boosters for Mac OS 10.5 These new QuickerTek drivers avoid the problems reported by early users of Leopard and wireless networking.
