Startup Security Utility

Hi there, just got a new MacBook Pro 14inch with the M1pro. I want to allow ''user management of kernel extensions from identified developers'' in ''Security & Privacy'' But I just can't find a way to do it. Here's what I do :


1. Shut down the Mac

2. Press and hold the power button until you see “Loading startup options”

3. Click Options

4. Click Continue

* If asked, select a user > Click Next > Enter password for admin account

5. In the menu bar at the top, Select Utilities > Startup Security Utility

6. Select the startup disk

* If the disk is encrypted, Click Unlock > Enter Password > Click Unlock

7. Click Security Policy

8. Select Reduced Security

9. Put a check next to “Allow user management of kernel extensions from identified developers”

10. Click OK

11. Enter admin password > click OK

12. Once changes are applied, click the Apple icon and Restart


But at the step 5, I always get this message error :

''Security settings cannot be changed.

In order to change security settings, please power off your mac and then hold the power button to startup macOS Recovery.''


What should I do? I already tried to reinstall macOS Monterey (I cannot install Big Sur because my mac came with Monterey.


I'm pretty sure it's a bug

Are you actually shutting down, or are you just restarting.

You must press and hold from a shut down state. That is part of the security process so something can't get into those settings by restarting the Mac.

If you are shutting down, then I would take it into an Apple Store for help.


The operating system has nothing to do with it as it is independent of the OS.
