Apple has recently made an announcement regarding the release of low-level system components of the operating system MacOS 14.3, also known as Sonoma. These components include various elements such as Darwin and other non-GUI related libraries and programs. A total of 172 packages containing source texts have been published by Apple. It is worth noting that GNUDIFF and LIBSTDCXX packages have been removed in comparison to the previous MacOS 13 branch.
One of the key highlights of this release is the publication of XNU, which is part of the Darwin open project. The original texts of XNU are now available as slices of code related to the upcoming MacOS release. XNU is a hybrid core that combines the Mach core, components from FreeBSD, and the C++ API IOKIT project for driver development.
In addition to the MacOS release, Apple has also published open components used in the iOS 17.3 mobile platform. The publication includes two packages, namely Webkit and Libiconv.
