Darwin is the open source operating system from Apple that forms the base for macOS. PureDarwin is a community project that fills in the gaps to make Darwin usable.

PureDarwin

The PureDarwin project, which aims to make Apple's open-source Darwin OS more usable, is still actively maintained as of 2024. While development has been relatively slow, the project continues to progress through community contributions. PureDarwin focuses on creating a usable bootable system that is independent of macOS components, relying solely on Darwin and other open-source tools.

The project's main focus is providing useful documentation and making it easier for developers and open-source enthusiasts to engage with Darwin.

Test Build

The PD-17.4 Test Build is a minimal system, unlike previous versions like PureDarwin Xmas with a graphical interface. It’s distributed as a virtual machine disk (VMDK) and runs via software like QEMU.

Due to the lack of proprietary macOS components, the community must develop alternatives, leaving elements like network drivers and hardware support incomplete. This build is intended for developers and open-source enthusiasts to explore Darwin development outside of macOS​.

Based on Darwin 17, which corresponds to macOS High Sierra (10.13.x).
