macOS 11 Big Sur

macOS 11 Big Sur is an operating system that was designed and developed by Apple since 2020 alongside Apple’s personal computers. The system has been released on November 12, 2020 and is available as a Free Update, or is preinstalled on currently sold computers. This software gets the latest update (11.6) on September 13, 2021.

macOS 11 Big Sur is the first version of macOS dedicated to Macs powered by Apple-designed ARM processors. Apple announced the first Mac Apple silicon chip, the Apple M1, in the Mac mini 2020, MacBook Air 13-inch 2020, and MacBook Pro 13-inch 2020. Of course, Apple will support Intel-based Macs in the coming years, and Big Sur is also available as an update for them. Unfortunately, various Macs released in 2012 and 2013 are no longer supported by the latest OS.

The biggest change in the latest version of the system is the design of the user interface. Its changes include translucency in various places and a new color palette. All standard apps, as well as the Dock and the Menu Bar, are redesigned and streamlined, and their icons now have rounded-square shapes like iOS and iPadOS apps. Compared to iOS, Big Sur’s icons include more shading and highlights to give a three-dimensional appearance. System sounds are redone as well. The new OS also brings further integration with Apple’s SF Symbols, enabling easier use by third-party developers as UI elements for their applications through AppKitSwiftUI, and Catalyst, which makes it possible to unify third-party applications with the existing Apple-made design language.

An interface with quick toggles for Wi-Fi, Bluetooth, screen brightness and system volume has been added to the menu bar. This interface is functionally and visually similar to Control Center on iOS and iPadOS. The Notification Center is redesigned, featuring interactive notifications and a transparent user interface. Notification Center also features a new widget system similar to that in iOS 14, displaying more information with more customization than previously available.

On Macs based on Apple Silicon, macOS Big Sur will run iOS and iPadOS applications natively and without any modifications needed from developers. The first Macs that will be able to do this are the MacBook Air M1 2020, the Mac Mini M1 2020, and the MacBook Pro M1 2020 with two ports.

Today macOS 11 Big Sur is 11 months old!
