What is Mach Unix?

Abstract. Mach is a multiprocessor operating system kernel and environment under development at Carnegie Mellon University. Mach provides a new foundation for UNIX development that spans networks of uniprocessors and multiprocessors. This paper describes Mach and the motivations that led to its design.

Why is Mac called Darwin?

It is derived from NextSTEP, which itself is built upon a BSD and Mach core, but Darwin is the open source portion of macOS. Historically, when Apple bought NeXT in the late 1990s, they built upon the NeXT operating system (NeXTSTEP) to form the basis of the next version of the OS for the Mac.
