I'm having an old MacBook Air 4.2, (mid 2011, SSD, 4 Gb memory), which have been running Catalina for quite some time despite that the max OS is High Sierra. I have been using the great work by dosedudes1 and his Catalina patcher.

Last year’s most significant WWDC event was a new version of macOS, Big Sur, and the announcement of the move to its own ARM processors. In macOS 11 (instead of the expected 10.16), Apple has massively redesigned the interface, added many new features and tools to move to new application architecture. We tell you which Mac models will be able to install macOS Big Sur.

The “Today” widgets in MacOS Big Sur are similar to the updated widgets in iOS 14. Other changes include an updated widget-enabled notification center, significantly improved messages, a powerful Safari upgrade, and more. Apple will release macOS Big Sur for all compatible Macs this fall.

Which Mac models will be supported by macOS Big Sur?

Supported devices that will receive MacOS Big Sur support:

  • MacBook 2015 and newer
  • MacBook Air 2013 and newer
  • MacBook Pro 2013 and newer
  • Mac mini 2014 and newer
  • iMac 2014 and newer
  • iMac Pro 2017 and newer

Apple also unveiled updated iOS, iPadOS, and watchOS. The new WatchOS 7 won’t support the Apple Watch Series 1 and 2, but iPhone and iPad users who support iOS and iPadOS 13 will be able to upgrade their devices to the next generation of OS seamlessly.
