NIST released an initial public draft of Special Publication 800-219 Revision 2, which documents the macOS Security Compliance Project, a collaboratively maintained set of machine-readable security baselines that let system administrators automatically generate and audit hardening configurations for macOS, iOS, and visionOS rather than hand-writing them against a static PDF checklist. The project itself lives as actively maintained code on GitHub, updated for each new Apple OS release, and this NIST publication is the formal, citable documentation of that project that auditors, compliance teams, and security policy authors can point to when they need a recognized standard to justify a configuration choice. Revision 2's main changes are aimed at making the project easier to actually adopt at scale: simplified OS version and rule management, and an explicitly broadened audience beyond just federal system administrators to include security professionals and auditors more generally. For anyone managing fleets of Apple devices in a regulated environment, this matters practically because automated is the operative word: instead of manually working through hundreds of individual settings, project-generated baselines can be applied and verified with configuration management tooling, and having them backed by a NIST Special Publication makes it far easier to satisfy compliance frameworks that require citing an authoritative source rather than an internal policy document. The draft was open for public comment through August 24, which means teams with real-world experience running the current baselines still had a direct channel to shape what ships in the final revision, worth knowing for anyone who has hit friction with the existing guidance and wants that feedback reflected in the finished standard.
