macOS reimagined and redesigned
The 17th release of the Apple Operating System, Big Sur is packed-full of changes and new additions. The various menu changes make it feel smoother and more efficient, and the additional customization options offer a more user-friendly system. A new design refresh, the introduction of a new Control Center, as well as various improvements to Safari, is set to greatly improve the overall experience from a usability standpoint.
New system features
Most noticeable are the new system sounds, from a chime when you boot up your computer and file transfer pings to noise alerts for trashing and locking files. Along with that, the overall interface has also been refined. Sidebars are now full height, the menu bar has been updated to offer wider spacing, the toolbars are remarkably more space-efficient, and they boast a translucent look instead of just a plain white.
Along with these tweaks, your new Control Center is convenient as it places your controls in one place, making it easy to adjust settings when needed. There’s also an updated notification center that brings all your widgets and notifications in one area. Of course, many different useful widgets have been improved as well. Finally, Big Sur boasts a great ‘edit view’ where you can add all sorts of widgets on your screen, and customize them to your liking.
Safari Browser
Safari Browser has seen some changes owing to the system update too. Apple has introduced extensions that let it compete more effectively with Google Chrome. You can also convert your Chrome extensions to your Mac Safari Browser. The search engine also has new website previews that appear when you go over a tab.
