macOS Catalina (version 10.15) is the sixteenth major release of macOS, Apple's desktop operating system for Macintosh computers. It is the successor to macOS Mojave and was announced at WWDC 2019 on June 3, 2019 and released to the public on October 7, 2019. Catalina is the first version of macOS to support only 64-bit applications and the first to include Activation Lock. It is also the last version of macOS to have the major version number be 10.x; its successor, Big Sur, released on November 12, 2020, is version 11. In order to increase web compatibility, various web browsers, such as Safari, Chromium, and Firefox, still inform websites that they are running on Catalina version 10.15.7, regardless of the actual macOS version in use.
The operating system is named after Santa Catalina Island, which is located off the coast of southern California.
macOS Catalina is the final version of macOS that supports the Unibody MacBook Pro, as its successor, macOS Big Sur, drops support for its mid-2012 and final model.
