Understanding Mac OS

Mac OS is the operating system that runs on Apple’s Macintosh computers. It is designed to be user-friendly, intuitive, and efficient. Mac OS is known for its sleek design, seamless integration with other Apple products, and its ability to handle a wide range of tasks. Over the years, Mac OS has undergone several updates, with the most recent one being Mac OS 11, also known as Big Sur.

Mac OS 11 – Big Sur

Mac OS 11, also known as Big Sur, was released in November 2020. It is the first version of the operating system to have a major number change in over two decades. Big Sur brings a fresh new look to the Mac, with a revamped user interface, new icons, and a refined design language.

One of the most significant changes in Big Sur is the introduction of Control Center. This feature brings together many settings and options that were previously scattered across the system. Users can now access Wi-Fi, Bluetooth, Do Not Disturb, Dark Mode, and other settings from a single location.


Mac OS 11, or Big Sur, is compatible with most Macs that were released in 2013 or later. This includes the MacBook Air, MacBook Pro, Mac mini, iMac, and Mac Pro. If you have an older Mac, you may not be able to upgrade to Big Sur, but you can still run an earlier version of Mac OS.
