The MacOS Startup Security Utility is a valuable tool for managing the security settings of your Mac’s startup process. If you are encountering the error message “No Administrator Found” when trying to access the Startup Security Utility, there are a few steps you can take to address this issue.

First, ensure that you are logged in to your Mac with an account that has administrator privileges. If you are not, log out and log back in with an administrator account.

If you are still unable to access the Startup Security Utility, you may need to reset the NVRAM (non-volatile random-access memory) on your Mac. To do this, restart your Mac and immediately hold down the Command + Option + P + R keys until you hear the startup chime for the second time.

If the issue persists, you can try resetting the System Management Controller (SMC) on your Mac. The process for resetting the SMC varies depending on the model of Mac you have, so you may need to consult Apple’s support documentation for specific instructions.

If none of these steps resolve the issue, it may be necessary to boot your Mac into Recovery Mode and use Disk Utility to repair any disk errors that could be causing the problem.

First, ensure that your UEFI settings are correctly configured to allow for booting from the appropriate device. If you’re using a USB flash drive to boot your MacOS Mojave or MacOS Big Sur system, make sure it’s properly inserted and recognized by your computer.

If you’re experiencing issues with disk partitioning or booting from a recovery disc, you may need to use Disk Utility to check and repair your disk. This can help resolve any underlying issues with your hard disk drive or solid-state drive.

In some cases, the error message may be related to user credentials or encryption settings. If you’re unable to access the MacOS Startup Security Utility, try logging in as a superuser or using an alternate login method.

If you’re using a MacBook, MacBook Pro, Mac Mini, or any other Mac computer, make sure you’re running the latest version of the operating system and that all software updates are installed.
