Apple has released another system update for Mac OS X – version 10.1.1.

The update is currently available using the Software Updates control of Mac OS X. It delivers improvements for USB and FireWire devices, including support for more models of digital camera, as well as improvements to CD and DVD burning from the OS.

Enhancements have also been made to some of the OS X's protocols, including WebDAV (World Wide Web Distributed Authoring and Versioning), SMB (Server Message Block Protocol) and AFP (Apple Filing Protocol). Printing support is also improved by the update.

The company's engineers have improved the Finder and the Mail application, and accelerated video-mirroring has been enabled for PowerBook G4s.
