The XNU version string for Beaker1N5 is Mac OS Version 10.0: Fri Apr 30 23:26: root(rcbuilder):Objects/xnu-24.6.obj~2/RELEASE_PPC powerpc. Much like in PowerPC builds of Rhapsody and Server 1.x, it includes the Blue Box emulation layer, which runs a copy of Mac OS 8.6 inside the emulator.
Unlike later Developer Previews, this preview's installation method involves booting to a Mac OS 8.6 pre-installation environment and starting the setup program from there, instead of instantly booting to setup.
The Developer Preview is overall similar to Mac OS X Server 1.0 in appearance and functionality, and still utilizes the Platinum theme.
It was introduced and distributed at the Worldwide Developers Conference on, showcasing the Darwin kernel to Mac OS and the bases for the completed operating system. Mac OS X Developer Preview 1 is the first Developer Preview of Mac OS X Public Beta.
