New Design
The first change you’ll see in macOS Big Sur is its brand new design. Everything from the icons to the windows and the apps themselves have changed to give macOS a simpler and cleaner look.
Everything looks new and yet, still looks familiar. Apple used a similar design to what we’ve seen in iOS and iPadOS, while still giving Big Sur its own aesthetic changes.
The top menu bar is also different. Now it’s more transparent and you can customize the controls from the Control Center (more on this later). And at the bottom, you’ll see a slight change to the Dock as well.
Now, instead of going all the way to the bottom, the Dock was lifted to “float” at the bottom. It’s also more translucent and lets you see your apps and your wallpaper more clearly.
The sounds in Big Sur have also changed. Apple added new sounds that are more pleasing to your ears. All that while still using snippets from older sounds so that you’ll recognize them easily.
