The Macintosh is a family of personal computers designed, manufactured, and sold by Apple Inc. since January 1984.
Apple has also developed a series of Macintosh operating systems. The first versions initially had no name but came to be known as the "Macintosh System Software" in 1988, "Mac OS" in 1997 with the release of Mac OS 7.6, and retrospectively called "Classic Mac OS". In 2001, Apple released Mac OS X, a modern Unix-based operating system which was later rebranded to simply OS X in 2012, and then macOSmacOS in 2016. The current version is macOS Mojave, released on September 24, 2018. Intel-based Macs are capable of running non-Apple operating systems such as Linux, OpenBSD, and Microsoft Windows with the aid of Boot Camp or third-party software.
