It is crucial to understand that PureDarwin is a "free alternative to macOS" in the sense that it can run Mac applications. PureDarwin OS Core Darwin (Open Source) Darwin (Open Source) GUI X11/Window Maker/GNUStep Aqua (Proprietary) Frameworks Basic/Open Source Cocoa/Carbon (Proprietary) App Store License Mostly APSL/BSD Proprietary
Perhaps the most important factor in PureDarwin’s future is community growth. The project has explicitly called for supporters and coders to accelerate development while demonstrating to Apple that there’s genuine interest in open Darwin development.

Furthermore, PureDarwin is a small community project with no funding and a core of volunteer developers. This inevitably leads to slower development, which is understandable for an open-source project of this scope. Apple itself does not directly contribute to the project.
The project was founded in 2007 as the informal successor to , a previous effort that closed down in 2006. Following OpenDarwin's closure, it became increasingly difficult for enthusiasts to build a full OS from Apple's releases as more components became proprietary. PureDarwin emerged to provide bootable images, documentation, and the necessary open-source tools to make Darwin accessible to developers again. Core Architecture and Features

Because hardware driver support is minimal (no Wi-Fi, no sound, limited SATA controllers), you are strongly advised to use virtualization.
The project describes itself as the a similar but now-defunct project that shut down in 2006. While OpenDarwin at one point could run a GNOME desktop, it ultimately failed due to difficulties building and tracking sources, limited interaction with Apple representatives, and a lack of community interest. PureDarwin seeks to avoid these pitfalls with a more pragmatic, step-by-step approach. Make Darwin easier to use by creating bootable ISO images
When Apple releases a new version of macOS, it simultaneously releases the source code for its core components under the Apple Public Source License (APSL). This core includes XNU (the kernel), the Libc runtime libraries, and various command-line tools.
For those who believe in open-source software, PureDarwin represents an ideological statement: the core of Apple’s operating system can and should be open and accessible to everyone. The project explicitly calls for supporters and coders to help “show Apple that there is still a community of open source Darwin supporters that would like to see more open-ness from them.”
Despite the undeniable progress and ambition, an independent project like PureDarwin faces unavoidable hurdles. Because it rejects all proprietary Apple code, many hardware components that would "just work" in macOS lack drivers. The OS cannot use drivers from macOS itself and must instead rely on incomplete open-source reimplementations or generic fallbacks, which results in limited hardware support and missing functionality like Wi-Fi and graphics acceleration.
