OS X, or macOS, is an operating system (OS) developed by Apple and designed to run on Macintosh computers, such as the iMac and MacBook. macOS was originally released in 2001 and is based on NeXTSTEP, an operating system developed by NeXT, which Apple acquired when Steve Jobs returned to Apple in 1997. Both NeXTSTEP and macOS are Unix-based and use the same Mach kernel. The OS was called "Mac OS X" until version OS X 10.8 when Apple dropped "Mac" from the name. Then, "OS X" changed to "macOS" with the release of macOS 10.12 Sierra in 2016.

The operating system comes bundled with a variety of applications, such as iTunes, Safari, iMovie, Photos, Books, QuickTime Player, and TextEdit, that can be used for a variety of purposes, such as listening to music, surfing the web, viewing photos, and reading eBooks. Finder is the desktop interface for macOS and includes several standard features. macOS includes a menu bar, which is fixed at the top of the screen. The Finder also includes a Dock, which is displayed by default at the bottom of the screen, that enables you to organize all your applications, files, documents, downloads, movies, music, and pictures.

After Windows, macOS is the most widely used desktop operating system and is popular among personal, educational, and professional users.  The OS provides a variety of features that Apple consistently updates, with new versions released annually, typically in September. And even though the OS comes with Mac computers that are often more expensive than computers running Windows, macOS is still an impressive operating system.
