History

Development

The 2020 Developer Transition Kit

Big Sur was developed with Xcode as a dual-binary (referred to as Universal 2) that supports both Intel and Apple processors. Rosetta 2 will allow 64-bit Intel software to run in emulation on Apple processors. The first system provided by Apple to registered developers to run Big Sur natively on an Apple A12Z processor is the 2020 Developer Transition Kit.[1]

Issues

Installation bug

Users discovered that the macOS Big Sur installer may not accurately anticipate the free space needed for the upgrade, which requires about 35.5 GB plus an additional 13 GB for the installer inself. If the installation process runs out of drive space before the process is completed, the resulting failure would result in an unrecoverable install loop and potential data loss. The installation bug still exists as of the beta version of macOS 11.3.[2] It is also recommended to check Energy Saver settings so that the computer does not go to sleep during installation.[3]

Gallery

Big Sur includes dynamic desktops, which change according to time and lighting conditions.
