Mac OS X is an operating system for Apple Macintosh computers. In 2016 it was renamed to macOS.

[edit] OS X

Mac OS X is based on the Unix Mach kernel and is derived from the Berkeley Software Distribution (BSD) implementation of Unix in NeXTSTEP. NeXTSTEP was the object-oriented operating system developed by Steve Jobs' company "NeXT" after he left Apple in 1985. The Macintosh pioneered UI was then placed on top of the Unix core. This version has been shipped on all Macs since 2002.
