To prevent this from occurring, the Computer Store recommends backing up all documents and important information, formatting the hard disk and installing a clean copy of OS X 10.5.
Apple has now provided *Login & Keychain Update 1.0 for Mac OS X 10.5 Leopard*. This is said to address:

- Connecting to some 802.11b/g wireless networks.
- Changing the password of a FileVault-protected account.
