macOS Big Sur 11 is one of the biggest operating system that introduced with the included features Control Center, Fastest Safari App, Messages, Maps, Widgets, iPhone and iPad Apps in macOS Big Sur. These all features was introduced in 22nd June, 2020 by Apple Inc at WWDC “Worldwide Developer Conference”.

Also, alongside the macOS Big Sur operating system, Apple introduced the new ARM-Based Silicon Processor, iPadOS 14, Watch OS 14, iOS 14, Mac, MacBooks, and introduced some features of the iPhone 12.

Still, macOS Big Sur and other OS of Apple products are in the Beta version. But thanks to the world of developers that gives us the biggest opportunity that we can test the Beta version on our Windows, and Mac PC.

Later this year in September and October the Apple will release the final version of macOS Big Sur for you in App Store. Because of the enthusiasm of Developers Apple always releases the Beta version in the month of June.
