MacOS Big Sur

macOS Big Sur (version 11) is the seventeenth major release of macOS, Apple's operating system for Macintosh computers. The successor to macOS Catalina, it was announced WWDC 2020 on June 22, 2020, and was released to the public on November 12, 2020. It was succeeded by macOS Monterey, which was released on October 25, 2021. For the first time since OS X Yosemite six years earlier, macOS Big Sur features a user interface redesign. It features new blurs to establish a visual hierarchy, along with making icons more square and UI elements more consistent. Other changes include a revamp of the Time Machine backup mechanism, and the addition of the Control Center (which was previously introduced, exclusively for touch devices, with iOS 7). It is also the first macOS version to support Macs with ARM-based Apple silicon processors. To mark the transition, the operating system's major version number was incremented, for the first time since 2001, from 10.15 (macOS Catalina) to 11. The release of Big Sur was the first time the major version number of the operating system had been incremented since the Mac OS X Public Beta in 2000. The operating system is named after the coastal region of Big Sur in the Central Coast of California, continuing the naming trend of California locations that began with OS X Mavericks. macOS Big Sur is the final version of macOS that supports Macs with Nvidia graphics cards, specifically the 15-inch dual graphics late 2013 and mid 2014 MacBook Pro models, as its successor, macOS Monterey, drops support for those models.
