Encyclopedic overview

Mac OS X 10.0, codenamed "Cheetah", is the first major release of Apple's Mac OS X (now macOS) operating system. Released on March 24, 2001, it served as a successor to Mac OS 9 and the classic Mac OS as a whole.

Mac OS X introduced major changes to the Mac OS architecture and user interface; it adopted a new Unix-like architecture derived from elements of BSD and NeXTSTEP, which are intended to improve the operating system's stability and multitasking capabilities in comparison to the classic Mac OS. It incorporates a new graphical user interface known as "Aqua", which features increased use of transparency and animation effects, and a new application launcher known as the Dock. Mac OS X uses two main frameworks for applications, including Carbon, an updated version of the original Mac OS APIs, and Cocoa, an object-oriented infrastructure based on that of NeXTSTEP.
