|Version of macOS|
macOS Big Sur (11) is a version of macOS, which was released on 12 November 2020. It is the first version to support the ARM-based SoC architecture of current Macs. It drops official support for Intel HD 4000 GPUs, though they work as they did in Catalina. 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 update to 11.0.1.
It is the first version of macOS since 2000 to increment the major version number from 10 to 11.
