macOS

From RaySoft

macOS, originally Mac OS X, previously shortened as OS X, is a Unix-based operating system developed and marketed by Apple since 2001. It is the current operating system for Apple's Mac computers. Within the market of desktop and laptop computers, it is the second most widely used desktop OS, after Microsoft Windows and ahead of all Linux distributions, including ChromeOS and SteamOS.[1]

Mac OS X succeeded classic Mac OS, the primary Macintosh operating system from 1984 to 2001. Its underlying architecture came from NeXT's NeXTSTEP, as a result of Apple's acquisition of NeXT, which also brought Steve Jobs back to Apple. The first desktop version, Mac OS X 10.0, was released on March 24, 2001. Mac OS X Leopard and all later versions of macOS, other than OS X Lion, are UNIX 03 certified. The derivatives of macOS are Apple's other operating system: iOS, iPadOS, watchOS, tvOS, and audioOS. macOS has supported three major processor architectures: originally PowerPC-based Macs in 1999; Intel Core-based Macs from 2006; and self-designed 64-bit Arm Apple M series Macs since 2020.[1]
