How do I disable secure boot and enable external boot in recovery mode?
Last Updated 2 years ago

You definitely need the device's admin password. If not, this cannot be done.

Boot recovery mode by holding down Command and the R keys.

Choose Utilities > Startup Security Utility from the menu bar.

It will then prompt you to type in the admin password.

In the Startup Security Utility menu, you can

  1. Disable secure boot by clicking on “No Security” under Secure Boot
  2. Allow booting from external media

This will allow you to boot RECON Imager and image the Macbook.
