How to Install macOS Big Sur

Next, we will learn how to install macOS Big Sur. If you are installing a newer version than the existing one then just open up your macOS Big Sur Installer file and it'll start updating that old macOS into something more modern! But if want access older versions on macOS like Downgrade, you need a macOS USB bootable drive to clean install macOS.

When you clean install macOS Big Sur, all of your data on the partitions will be erased and then re-installed with new software. This process gives a fresh start that's perfect for those who want their Macs to look like they were brand new!

1. Backup your Data

You should back up your data before proceeding with the clean install. If you don't, all of that important information could be lost forever! You can use an external drive or create a new partition in Disk Utility for backup purposes if needed; just make sure not to miss any files because there is no going back once they've been deleted from disk: even after performing another restore process.

2. Create macOS USB Installer with Terminal

Now that you’ve formatted the USB drive, you’re ready to turn it into a bootable drive with the help of Terminal. Follow the steps mentioned below:

Create macOS Big Sur USB Installer

  • Search for the Terminal app with Spotlight Search and open it.
  • Copy and paste the following the commands in Terminal, replace ‘Untitled’ with your USB drive’s actual name.
    sudo /Applications/Install\ macOS\ Big\ --volume /Volumes/Untitled
  • Hit the Enter key and once you see “Done” written in the Terminal app, you’re ready to install macOS 11 Big Sur with the USB drive.

3. Boot to macOS USB Bootable

  • M1, M2 Mac: Turn on and hold down the power button on your Mac until you see Startup Options window, which will allow for booting from external drives.
  • Intel Mac: To access the bootable volumes on a Mac, press and hold Option key when turning it on or restarting. Release this key once you see your computer's startup screen displaying all available drives.

4. Use Disk Utility to Format Hard Disk

Before clean install macOS 11 Big Sur, it is always good to create a backup of your Data. So, connect an external device and backup your macOS with Time Machine.
