Apple Releases Darwin 1.0 Open Source

Apple has announced the release of Darwin 1.0, the operating system core at the heart of Mac OS X, and the release of an updated Darwin Streaming Server.

Darwin's open source model allows registered Darwin developers to modify, customize and extend Apple (AAPL) software, including the modern mach kernel and BSD layers found in Apple's next generation operating system, Mac OS X.

"The core of Mac OS X is the only mainstream operating system following an open source model," said Philip Schiller, Apple's vice president of Worldwide Product Marketing. "The new Darwin 1.0 posting includes some of the most advanced operating system technology available, and it's open to our customers and developers so that we may collaborate on the future of the Mac OS."

The new Darwin kernel is based on FreeBSD and Mach 3.0 technologies and supports the Kernel Extension Developer Kit (KDK) for developing drivers and loadable modules. Darwin 1.0 gives developers access to essential Mac OS X source code. This allows developers to enhance the feature set, performance and quality of Mac OS X products in partnership with Apple engineers. Darwin 1.0 is processor-independent and is built for PowerPC and Intel platforms, enabling Open Source developers to work on Darwin projects on a choice of computer systems.

In addition to Darwin 1.0, Apple also announced an update to the Darwin Streaming Server, the open source version of Apple's QuickTime Streaming Server software, which is used to stream audio and video. This update makes the Darwin Streaming Server available for Windows NT-based systems, expanding support for developers creating streaming server products based on five different operating systems -- Mac OS X, FreeBSD, Linux, Solaris and now Windows NT.
