1. Move the macOS Installer to the /Applications folder.
2. Open a terminal.
3. For macOS 10.12 and older, use command: sudo /Applications/<installer app name>.app/Content/Resources/createinstallmedia --volumes /Volumes/<USB Volume Name> --applicationpath /Applications/<installer app name>.app
4. For macOS 10.13 and newer, use the same command but omit the --applicationpath parameter and anything after it.
