The core operating system, which was based on BSD and the Mach kernel, was renamed Darwin after Apple acquired it. The deployment of Darwin in Mac OS X makes it, according to a statement made by an Apple employee at a USENIX conference, the most widely used Unix-based system in the desktop computer market.

Unix (/ ˈ j uː n ɪ k s / ⓘ, YOO-niks; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 [1] at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. [4]
Eventually, the tools developed by Thompson became the Unix operating system: Working on a PDP-7, a team of Bell Labs researchers led by Thompson and Ritchie, and including Rudd Canaday, developed a hierarchical file system, the concepts of computer processes and device files, a command-line interpreter, pipes for easy inter-process ...

After the release of Version 10, the Unix research team at Bell Labs turned its focus to Plan 9 from Bell Labs, a distinct operating system that was first released to the public in 1993. All versions of BSD from its inception up to 4.3BSD-Reno are based on Research Unix, with versions starting with 4.4 BSD and Net/2 instead becoming Unix-like.
Invention of the Micral N, the earliest commercial, non-kit personal computer based on a microprocessor. 1967 Thompson, Ken: Created the Unix operating system, the B programming language, Plan 9 operating system, the first machine to achieve a Master rating in chess, and the UTF-8 encoding at Bell Labs and the Go programming language at Google ...
