Discussion
Authenticated Root _MUST_ be enabled.
When Authenticated Root is enabled the macOS is booted from a signed volume that is cryptographically protected to prevent tampering with the system volume.
NOTE: Authenticated Root is enabled by default on macOS systems.
WARNING: If more than one partition with macOS is detected, the csrutil command will hang awaiting input.
