The Evolution of Darwin

Darwin has been a groundbreaking project on many fronts. Its hybrid BSD architecture is a technical triumph that makes life immeasurably better for both users and developers. What's more, putting the core of its commercial offering into the hands of the open source community has made Apple the first major computer manufacturer to fully embrace the open source movement. For Mac OS X developers and users alike, that move opens the door to the many benefits -- from better code to a stronger community -- offered by the open source model.
