3. Install macOS
After starting up from macOS Recovery, follow these steps to install macOS:
- Choose Reinstall macOS (or Reinstall OS X) from the Utilities window.
- Click Continue, then follow the onscreen instructions to choose your disk and begin installation.
If the installer asks to unlock your disk, enter the password you use to log in to your Mac. If it doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk. - Please allow installation to complete without putting your Mac to sleep or closing its lid. During installation, your Mac might restart and show a progress bar several times, and the screen might be empty for minutes at a time.
If your Mac restarts to a setup assistant, but you're selling or giving it away, press Command-Q to quit the assistant without completing setup. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete setup.

- Option-Command-R installs the macOS that came with your Mac, or the closest version still available.
- Shift-Option-Command-R isn't available.
