macOS CMMC Level 2 Checklist
macOS CMMC Level 2 Checklist
Quick answer: A Mac readiness checklist should cover scope, ownership, MDM enrollment, identity, FileVault, software updates, logging, approved software, removable media, backup, and SSP/POA&M documentation.
Why this matters for CMMC readiness
The checklist is not a substitute for the 110 NIST SP 800-171 requirements or CMMC assessment objectives. It is an endpoint-focused preparation tool for Mac environments.
Use it to make Mac-specific assumptions visible before an assessment: who owns the device, how it is enrolled, which controls are enforced, and what evidence can be produced without storing CUI in the wrong place.
Practical readiness checklist
- Inventory all in-scope Macs and owners.
- Record Apple Business Manager / MDM enrollment status.
- Verify FileVault status and recovery key escrow process.
- Document local admin restrictions and privileged access review.
- Verify software update enforcement and deferral policy.
- Confirm logging, retention, and central collection approach.
- Document iCloud, AirDrop, removable media, and external sharing restrictions.
- Map gaps into a remediation tracker.
CMMC and NIST relevance
| Area | Why it matters |
|---|---|
| AC | Account control, least privilege, sharing restrictions |
| CM | MDM baseline, approved settings, software inventory |
| MP | FileVault, removable media, data handling |
| SI | Patching, malware protection, vulnerability response |
| AU | Logging and review process |
What this does not prove
mSCP can support macOS hardening and assessment preparation, but it does not by itself prove CMMC compliance. Certification and assessment outcomes depend on scoping, implementation, documentation, evidence, assessment type, and required affirmations.

Template next step
Use the macOS CMMC Level 2 Checklist to turn this guidance into a working checklist or implementation artifact.
Readiness next step
Use the CMMC Operator readiness check to organize self-reported implementation status. Do not enter CUI, FCI, credentials, system configurations, or evidence into public tools.
FAQ
Is this an official checklist?
No. It is a readiness aid for planning and documentation.
Should every Mac be in scope?
Only if it processes, stores, transmits, or can affect systems handling FCI/CUI based on the organization scope.
