I'm trying to disable System Integrity Protection on an M1 Mac.
csrutil disable as well as
csrutil authenticated-root disable fail with an error:
csrutil: Failed to update security configuration for "Macintosh HD": Failed to create local policy
How can I avoid this failure? What is causing it?
This a brand-new Big Sur 11.0 (20A2411) on M1 MBP. FileVault is off. I'm booting into the new "Options" mode, and launching Terminal from there. Authentication is certainly OK, as I get a different error if I enter a wrong password. The user partition is accessible in this mode, I can write to
/Volumes/Macintosh HD/Users/me/ for example.
-bash-3.2# csrutil disable Turning off System Integrity Protection requires modifying system security. Allow booting unsigned operating systems and any kernel extensions for OS "Macintosh HD"?
