I'm trading in my iMac and after erasing the HD, it's not allowing a new OS install.

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.
