PRNewswire: Apple Releases Darwin 1.0 Open Source

“New Mac OS Core and QuickTime Streaming Server Released to
Tens Of Thousands of Developers.”

“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 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.”
