macOS 11 Big Sur has just been released. The update brings several important improvements to the operating system relative to the best Macs while offering additional stability.

macOS Big Sur follows in the footsteps of macOS Catalina, but if Catalina was a slight improvement in macOS Mojave, the new version of the system is the biggest change in Apple’s operating system in recent years. The main change is the switch to a chipset developed by Apple. Along with macOS Catalyst, the update finally provides full support for iOS and iPadOS apps in Mac operating systems. Apple has also worked on improving efficiency and power.

We also noted a change in the appearance of native macOS applications. Apple introduced the changes with Messages, Mail, Photos, Calendar, and even Finder, all in a new, much more compact and optimized design. We’ll also finally get improvements that are more in line with iOS updates with macOS Big Sur, including the widget feature that came with iOS 14 and iPad 14, which makes the entire Apple product experience more harmonious and solid.

This is also the biggest macOS update in recent years, so we have a lot to discuss. Be sure to keep this page in bookmarks. We will update it with fresh information and features.

macOS 11 Big Sur: System Requirements

Making Mac Os Bootable Usb On Windows

If you want to download and install macOS 11, you’ll have to make sure your Mac is actually able to run it. And, unfortunately, the system requirements of macOS have grown with the update. We went ahead and listed the Big Sur-compatible Macs below.

  • Apple MacBook 12 (2015 and newer);
  • Apple MacBook Air (2013 and newer);
  • Apple MacBook Pro (2013 and newer);
  • Apple Mac Mini (2014 and newer);
  • Apple iMac (2014 and newer);
  • Apple iMac Pro (all models);
  • Apple Mac Pro (2013 and newer);

macOS 11 Big Sur: Features


Safari is an underrated macOS hero. The improvements that come with the new update make the browser faster – now, according to Apple, it’s 50% faster than Chrome – along with simultaneously improved privacy and optimized energy consumption. But that’s not all. Presumably, this is the biggest update Apple has received since its first release.

The new version of Safari promises a host of new features, including smart tracking that provides you with a privacy report for every site you visit, saves passwords from tracking them for hacking attempts, supports extensions for WebExtensions API, and gets a selection of new extensions in the App Store, along with a built-in translation feature.

There’s one interesting feature here: the browser homepage has become extremely customizable, so you’ll be able to change the background image and add/edit sections.


This service’s capabilities have been inferior to their iOS analog for some time, but now you’ll be able to use Pinned Messages, Notes, and Updated Groups that will come with iOS 14, which is nice. Basically, all updates share the iOS 14 features, which is nice to see. The update will also offer a better search, a redesigned sample of photos, and new effects in messages.

Airpods Update

Besides the exciting support for Spatial Audio for AirPods Pro, we expect significant improvements in AirPods support in macOS. Instead of messing with Bluetooth settings, every time you want to use headphones with your Mac, they automatically switch to a Mac when you start using your computer. AirPods will now easily and intuitively switch between devices without any additional action.

Sidebar in Mail and Photos

Apple Mail and Photos apps are long out of date, so Apple has introduced a new design for most of its apps, among which the new sidebars in Mail and Photos are the most visible. The Photos app will look the same as the iOS 14 version.

MAC Control Center

One of the best things about iOS is the very convenient Control Center, which allows you to change many settings on the go. macOS Big Sur will transfer this functionality to Macs, providing easy access to them from the menu, so you can easily change the most popular settings without going to a separate Settings app.

Widgets in Notification

As with iOS 14, macOS 10.16 Big Sur has widgets for the notification menu, making it easier to access important information with a user-friendly interface. These widgets can be customized to suit your needs and preferences.

MAC Catalyst

An important addition to macOS Mojave has been the integration of some popular iOS apps. But with Mac Catalyst, new APIs and tools for app developers promise to move even more iOS apps into the Mac operating system. With these tools, you get features such as changing window size, keyboard tools that allow you to transform your app into a Mac environment, breaking away from the problems of ported apps with the iPhone.
