Description
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.
