An open-source alternative to Apple Mac OS X. Intended to comply completely with the OPENSTEP specification. Written in Objective-C. Kernel based on FreeBSD.
Hobbyist operating system using a new microkernel. The objective is to not get bogged down by ancient legacy processor support. The OS is meant to be designed from the ground up, without utilizing any legacy or existing implementations or designs.
The Darwin Source repository is intended to fill a void left by the closure of the OpenDarwin project: providing a permanent and public repository for the open source components of Mac OS X.

The goal of llama-X is to be a cutting-edge desktop operating system for the x86 architecture. A new object-oriented filesystem, and a fresh new desktop paradigm, and an innovative multikernel subsystem are main features of the system.
