What are the new features in macOS Big Sur?
Safari reborn
Apple's Craig Federighi dubbed the current update 'The biggest update in the history of Safari.' It's been shown to outperform Chrome in various tests — another reason for Mac users to feel proud. Now you can customize Safari like never before, set the start page theme, control videos from the menu bar, etc. And, to the dismay of marketers, Safari gives you an option to switch off all your tracking cookies.
Fancier icons
The Dock panel got a full on facelift featuring smaller icons, round edges, more in tune with iOS look. For the last few years Apple has been merging both systems together, and now the gap between the mobile and Mac seems to be almost unnoticeable.
Control Centre
Control Centre is the new quick-access pane that shines in Big Sur's upper right corner. From there you can adjust volume, screen brightness, and finally, access Bluetooth in one click. Control Centre has handy toggles and keeps all the important controls in one place making it an instant like.
64-bit applications
If you skipped macOS Catalina and, are still running macOS Mojave, there is an issue about 32-bit apps you should know about. Before Catalina the 32-bit / 64-bit app distinction was known only to programmers. These numbers represent different types of app architecture. Starting macOS Catalina and continued on Big Sur, 32-bit apps will no longer be supported on Macs. For many users this will be the single reason to avoid it and stay with good ol' Mojave. Some big name applications, are still yet to be optimized for Big Sur and 64-bit.
If you're still planning to upgrade, there are tools to make the transition less painful. For example, the Mac problem-fixing tool, CleanMyMac X, has an Updater feature. It checks how many 32-bits you have and updates them to newer versions (if such are available).
