macOS Big Sur, or macOS 11, is the seventeenth major release of macOS that was released on 12 November 2020. It was announced on 22 June 2020 at WWDC. It is the first version to support the ARM-based SoC architecture of current Macs. This version has no 11.0 release for Intel-based Macs, even though the OS's beta-testing phase began with said version number, instead, the public release for Intel-based Macs jumped the version number to 11.0.1. Version 11.0 has been pre-installed on some early M1 Macs, and Apple recommends that users running this version must update them to 11.0.1.[1]

It is the first version of macOS since 2000 to increment the major version number from 10 to 11. It is also the first version of macOS to include Rosetta 2 for running and emulating x86-64 applications and the Universal 2 binary that enables applications to run on both Intel x86-64-based and ARM64-based Macs.
