title: Enable Authenticated Root
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.

  /usr/libexec/mdmclient QuerySecurityInfo 2>/dev/null | /usr/bin/grep -c "AuthenticatedRootVolumeEnabled = 1;"

fix: |
  [source,bash]
  ----
  /usr/bin/csrutil authenticated-root enable

  NOTE: To re-enable "Authenticated Root", boot the affected system into "Recovery" mode, launch "Terminal" from the "Utilities" menu, and run the command.
