The XNU hybrid kernel (Mach + BSD + IOKit) that powers macOS and iOS, mirrored by Apple on GitHub. This legacy mirror is no longer updated and has been replaced by the apple-oss-distributions/xnu repository.
Use cases
- study how the macOS and iOS kernel is implemented
- build a custom XNU kernel for research or debugging
- explore Mach microkernel and BSD subsystem source code
- develop and debug kernel extensions (kexts) and drivers
- research kernel internals for security analysis
When to choose
- you need the historical source of the Darwin kernel as originally mirrored by Apple
- you are studying legacy XNU source for research or education
When to avoid
- you want current XNU source - use apple-oss-distributions/xnu instead
- you need ARM/Apple Silicon kernel sources, as this mirror targets x86_64
- you want an actively maintained project or official support
