Big Sur

Big Sur is like a big fancy house for your computer to live in. It's a new version of Apple's operating system (the thing that makes your computer work) that came out in 2020. Just like how you might move into a new house and things look different, Big Sur makes your computer look a little different too. It has new features and improvements to help make your computer better and easier to use. Think of it like getting a new toy - it's exciting and fun to explore all the cool things it can do!
