The macOS system must audit the enforcement actions used to restrict access associated with changes to the system.
By auditing access restriction enforcement, changes to application and OS configuration files can be audited. Without auditing the enforcement of access restrictions, it will be difficult to identi...Rule Medium Severity -

Group -
The macOS system must allocate audit record storage capacity to store at least one week's worth of audit records when audit records are not immediately sent to a central audit record storage facility.
The audit service must be configured to require that records are kept for seven days or longer before deletion when there is no central audit record storage facility. When "expire-after" is set to ...Rule Medium Severity -

The macOS system must provide an immediate real-time alert to the System Administrator (SA) and Information System Security Officer (ISSO), at a minimum, of all audit failure events requiring real-time alerts.
The audit service should be configured to immediately print messages to the console or email administrator users when an auditing failure occurs. It is critical for the appropriate personnel to be ...Rule Medium Severity -
SRG-OS-000470-GPOS-00214
Group -
The macOS system must generate audit records for DoD-defined events such as successful/unsuccessful logon attempts, successful/unsuccessful direct access attempts, starting and ending time for user access, and concurrent logons to the same account from different sources.
Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an in...Rule Medium Severity -
SRG-OS-000376-GPOS-00161
Group -
The macOS system must accept and verify Personal Identity Verification (PIV) credentials, implement a local cache of revocation data to support path discovery and validation in case of the inability to access revocation information via the network, and only allow the use of DoD PKI-established certificate authorities for verification of the establishment of protected sessions.
The use of PIV credentials facilitates standardization and reduces the risk of unauthorized access. Without configuring a local cache of revocation data, there is the po...Rule Medium Severity -

Group -
The macOS system must require individuals to be authenticated with an individual authenticator prior to using a group authenticator.
Administrator users must never log in directly as root. To assure individual accountability and prevent unauthorized access, logging in as root over a remote connection must be disabled. Administra...Rule Medium Severity -

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
