Install for macOS Big Sur's UI
macOS Big Sur 11.1 brought Apple News widgets to Notification Center. It also brought new ways to use multiple windows and apps at the same time if you own an M1-powered MacBook.
If either of those upgrades sound useful, and you skipped macOS Big Sur 11.2.2, macOS Big Sur 11.2.1, macOS Big Sur 11.2, and macOS Big Sur 11.1, you should think about installing the macOS Big Sur 11.2.3 update today.
If you're still running an older version of macOS, you might want to make the move to macOS Big Sur for the design changes.
macOS Big Sur brings a new design to your Mac. Apple changes the curves of windows, the colors, and the way windows look throughout.
The icons and the Dock both are new with style changes that better match the look and feel of iOS.
The menu bar is upgraded and now you can use a familiar-looking Control Center for the first time on Mac.
You also get an updated Notification center that comes with new widgets, similar to the widgets that came with iOS 14 and iPadOS 14.
