macOS 11 Big Sur is the seventeenth version of the macOS operating system developed by Apple inc. It is the successor to macOS Catalina and was announced at the Worldwide Developers Conference (WWDC) on June 22, 2020. Named after the coastal area of Big Sur, located on the central coast of California, USA. macOS Big Sur has been defined by Apple itself as the biggest update since the release of Mac OS X Cheetah, so much so that the version number has gone from 10 (X) to 11 after almost twenty years. During the Apple event on November 10, 2020, the official publication from the following November 12 was announced. In the first few hours of publication, many users had trouble installing.
