macOS Big Sur brings a refined new design, powerful controls and intuitive customisation options to the most advanced desktop operating system in the world.

Safari

What's new: Perhaps the biggest upgrade in MacOS Big Sur comes in Apple's Safari web browser. Apple said that this is the biggest update to Safari since its launch in 2003. The revamped browser will load the websites you visit most often faster, and have better tab management capabilities. You'll also find improved privacy features, including a privacy report button that lets you see how websites track your data and monitor if any of your passwords were compromised in a security breach

A new App Store category for Safari extensions will let you customize which sites and times each extension is used, if you don't want it running all the time. And a customizable Safari start page will let you pick from a curated group of wallpapers or use one of your own photos. You can also use it to translate languages from seven different languages with a built-in feature.
