Apple has released another update for Mac OS X – version 10.0.3.

The updater appeared yesterday and is available for download using the Software Updates feature of OS X. It can also be downloaded from the company's Web site.

In a confusing note, Apple says the update is designed to deliver CD-burning support for iTunes and adds that it improves the application's stability, as well as offering security enhancements to the Internet file transfer service (ftpd). This in fact applies to the existing 10.0.2 updater - update 10.0.3 simply checks that file lists in directories containing many items are fully visible.

This is the third update Apple has posted since the March 24 release of Mac OS X. Apple CEO Steve Jobs underlined Apple's commitment to its next-generation, UNIX-based OS during the company's iBook presentation on Monday May 2, saying: "There are always bugs we need to fix and features we need to add."
