No administrator was found

I wanted to run a Windows to go on my new MacBook Pro 2018 with an external drive, because it has the Apple T2 chip (About Startup Security Utility - Apple Support), I have to run the Startup Security Utility to allow booting from external media.

But when I see the macOS Utilities window, and choose Utilities > Startup Security Utility from the menu bar, it asked me to Enter macOS Password. When I clicked it, it said that "Recovery is trying to change system settings. NO administrator was found."

Actually I do have an admin account on my Mac and I don't know why it happened.

MacBook Pro (15-inch, 2018), macOS High Sierra (10.13.6)

I’m having the same problem, using the new Mac Mini late 2018 with the T-2 chip. Unfortunately, my machine is not bootable, since my hard disk appears to have become corrupted, and cannot be recovered via Time Machine or reinstalling Mojave. Neither recovery can be performed since I am missing this administrator login and cannot change the security settings for the disc.

I wish I had a way to toggle the FileVault system preferences, but with no way to boot, I have no access to this method.

I would very much appreciate any suggestions for someone in my situation, with no apparent way to restore my internal hard disk, which is now locked out but corrupted.

Thanks very much,

Larry

I can't set a firmware password by the Startup Security Utility without an admin account to log in.

I just don't know why it said "NO administrator was found" while I do have one.

Hi Robert.

I believe your problem could have an answer in a new topic.
