MacOS Big Sur

macOS Big Sur (11.x) is a version of macOS that was released on 12 November 2020. It is the first version to support the new ARM-based SoC architecture of future Macs. It drops support for Ivy Bridge CPUs. 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 release of Big Sur jumped directly to 11.0.1 for that architecture. However, 11.0 was pre-installed on ARM-based Macs, and Apple advises users with this version to update to 11.0.1.
