Macos Versions

This doc lists the different versions of macos released (and still supported and tested by libproc-rs) along with the corresponding versions of Darwin and `XNU used in each.

It also lists the public (via libproc.h header file) functions provided by libproc in each version, and shows in what version new functions were added.

What is XNU

XNU kernel is part of the Darwin operating system for use in macOS and iOS operating systems.

Here you can find the XNU version tags that apple has tagged in the GH project

What is Darwin

Darwin is the core Unix operating system of macOS (previously OS X and Mac OS X), iOS, watchOS, tvOS, iPadOS, visionOS, and bridgeOS. It previously existed as an independent open-source operating system, first released by Apple Inc. in 2000. It is composed of code derived from NeXTSTEP, FreeBSD,[3] other BSD operating systems,[6] Mach, and other free software projects' code, as well as code developed by Apple.
