What to do before you sell, give away, or trade in your Mac


Use Disk Utility to erase an Intel-based Mac


How to reinstall macOS This will require an Internet Connect and preferred via Ethernet Cable to Router

  • If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
  • If the installer 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 first.
  • If the installer offers you the choice between installing on Macintosh HD or Macintosh HD - Data, choose Macintosh HD.
