Questions Tagged [mach]

Mach is the name of the foundational component of the XNU kernel, common to macOS, iOS, tvOS and watchOS. Originally developed by CMU, it was adopted by NeXTSTEP, and integrated into macOS (formally known as Mac OS X) when the former merged with Apple. Though largely undocumented, Mach APIs make up the core of XNU's IPC, scheduling and memory management, supplementing the more widely known POSIX APIs offered in Darwin.
