Mac OS X 10.3.1 Update

Mac OS X 10.3.1 (Build 7C107) Update is now available in your software update:


    The 10.3.1 Update delivers enhanced functionality and improved reliability for the following applications, services and technologies: FileVault, Printing, WebDav, and FireWire 800 drives. This update also includes the latest Security Updates.

    Important Note: Apple has identified an issue with external FireWire hard drives using the Oxford 922 bridge chip-set with firmware version 1.02 that can result in the loss of data stored on the disk drive. Even with the improvements available in this update, Apple recommends you update the firmware on your FireWire drive. Please contact your drive manufacturer for more information.

This update presumably addresses previously reported Panther issues related to Filevault and Firewire drives.

Build 7C107 was briefly seeded to developers over the weekend.
