macos-intune-baseline

macos-intune-baseline is a skill for Claude Code, Codex from vinayaklatthe/microsoft-security-skills. It costs 224 tokens per session (2,225 once invoked), scanned A, original, MIT.

Guidance for securing Mac computers managed through Microsoft Intune, Microsoft's device-management service. It covers enrollment, company sign-in, disk encryption, approved applications, firewall settings, and security configuration.

In plain words
What is it for?
Use it to design or review Intune-managed macOS setups, including Apple Business Manager enrollment, Platform SSO with Entra ID, FileVault encryption, application controls, and Microsoft Defender for Endpoint.
Why use it?
It helps organizations apply consistent protections to Mac fleets and use device compliance in access decisions. It also addresses recovery-key storage and the gap between Mac and Windows management.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

macos-intune-baseline scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

macOS Hardening with Microsoft Intune

Mac fleets in Microsoft-shop enterprises are usually under-governed compared to Windows. Intune-managed macOS with the right configuration profiles, FileVault escrow, Defender for Endpoint, and Platform SSO with Entra ID closes most of the gap and gives you a Conditional Access compliance signal that actually means something.

When to use

Designing or hardening macOS endpoint management in an Intune + Entra ID environment (workforce devices, BYOD via user-enrollment is a separate model).

Do not use this skill for end-to-end Intune (intune-device-mgmt), MDE policy authoring (defender-for-endpoint), or iOS / iPadOS management.

Capability map

Layer Tool / Profile
Provisioning Apple Business Manager + Intune Automated Device Enrollment
Identity / SSO Platform SSO (Entra ID), Enterprise SSO plug-in
Disk encryption FileVault enabled + escrow recovery key to Intune
App control Gatekeeper, XProtect (Apple-managed), notarized apps allowlist via system extensions
Endpoint protection Microsoft Defender for Endpoint on macOS
Configuration Settings catalog profiles (preferred), legacy templates where required
Privacy / kernel Privacy Preferences Policy Control (PPPC), System Extensions, Notification Center policy
Updates Managed Software Updates / Declarative Device Management (DDM)
Compliance Intune compliance policy → Conditional Access

Approach

  1. Enroll via ABM + Automated Device Enrollment. Manual enrollment is fine for pilots; production needs ABM so devices arrive supervised, can't be unenrolled by the user, and pick up policy at first boot.

  2. Platform SSO (PSSO) with Entra ID is the modern macOS SSO. User signs into the Mac with their Entra credentials (password, smart card, or passkey-style secure enclave). Replaces the older Enterprise SSO plug-in for sign-in scenarios. Requires deployment of the Microsoft Enterprise SSO plug-in package + a PSSO configuration profile.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
