External Boot

Use this feature to control whether your Mac can start up from an external hard drive, thumb drive, or other external media. The default and most secure setting is ”Disallow booting from external media.” When this setting is selected, your Mac can't be made to start up from any external media:

  • Startup Disk preferences displays a message that your security settings do not allow this Mac to use an external startup disk.
  • Startup Manager allows you to select an external startup disk, but doing so causes your Mac to restart to a message that your security settings do not allow this Mac to use an external startup disk. You'll then have the option to restart from your current startup disk or select another startup disk.

To allow your Mac to use an external startup disk:

  1. Open Startup Security Utility.
  2. Select ”Allow booting from external media.”
    Your Mac doesn't support booting from network volumes, whether or not you allow booting from external media.
  3. If you want to select an external startup disk before restarting your Mac, quit Startup Security Utility, then choose Apple menu  > Startup Disk.
