If you need to erase it before installing macOS, select Disk Utility from the Utilities window, then click Continue. Find out more about when and how to erase your disk.

3. Install macOS

When you're ready to reinstall macOS, choose Reinstall macOS from the Utilities window. Then click Continue and follow the on-screen instructions. You will be asked to choose a disk on which to install.

If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
If the installer can't see your disk or notifies you that it can't install macOS on your computer or volume, you may need to erase your disk first.
If the installer is for a different version of macOS than expected, find out about macOS Recovery exceptions.
If the installer offers you the choice between installing on Macintosh HD or Macintosh HD – Data, choose Macintosh HD.

Please allow the installation to finish without putting your Mac to sleep or closing its lid. During the installation process, your Mac may restart and display a progress bar on the screen several times, and the screen may be blank for minutes at a time.

If your Mac restarts to a setup assistant, but you're selling, trading in or giving away your Mac, press Command-Q to quit the assistant without completing the setup process. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete the setup process.

If you erased your entire disk instead of just the startup volume on that disk, macOS Recovery may only offer the macOS that came with your Mac, or the closest version that's still available. You can upgrade to a later version afterwards.
If your Mac has the Apple T2 Security Chip and you've never installed a macOS update, Option-Command-R installs the latest macOS that was installed on your Mac.
If you've just had your Mac logic board replaced during a repair, macOS Recovery may only offer the latest macOS that is compatible with your Mac.
