Apple Releases Darwin 1.0 Open Source

New Mac OS Core and QuickTime Streaming Server Released to Tens of Thousands of Developers

INTERNET WORLD, LOS ANGELES—April 5, 2000—Apple® today announced the release of Darwin 1.0, the advanced 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 the tens of thousands of registered Darwin developers to modify, customize and extend key Apple 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 the widest 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 high-quality audio and video over the Internet. The Darwin Streaming Server is the only open source, standards-based and free Internet streaming server. 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.

Availability and Pricing
Darwin 1.0 is available for immediate download at www.apple.com/darwin. The CD set will be available from the Apple Developer Connection website, www.apple.com/developer, for US$20. Darwin Streaming Server will be available in May.
