Deploying macOS FileVault with Microsoft Intune: What You Need to Know

Apple’s FileVault has been a cornerstone of macOS security since 2005. But deploying it effectively in an enterprise environment requires modern tools and strategies. Microsoft Intune now offers a streamlined way to enable and manage FileVault on macOS devices, especially for those running macOS Sonoma (version 14) or later.

What’s New with FileVault and Intune?

FileVault 2, introduced in 2011, was a game changer. Now, with macOS Sequoia and later, you can unlock FileVault using Microsoft Entra ID credentials via Platform SSO. This integration simplifies authentication and boosts security.

“FileVault enhances security by linking encryption to the user’s login password in addition to the hardware-based key.”

Apple silicon Macs and Intel Macs with T2 chips are encrypted by default at the hardware level. However, FileVault adds a user-aware encryption layer that’s policy-enforceable through Intune.

Major Updates in Deployment with Intune

Microsoft Intune’s Settings Catalog is now the recommended way to deploy FileVault. It avoids policy conflicts and ensures consistent behavior across all managed Macs. Here’s a quick rundown of the setup:

Login to Microsoft Intune admin center
Create a new macOS configuration profile using Settings Catalog
Enable FileVault and configure recovery key rotation (e.g., every 6 months)
Force enable FileVault during Setup Assistant for seamless encryption
Escrow recovery keys securely within Intune, accessible only to authorized admins

Note that dynamic device groups don’t support forced enablement during Setup Assistant, so static groups or all-device assignments are preferred.

Recovery Key Management and Troubleshooting

The recovery key is crucial for regaining access if users forget their passwords. Intune securely stores these keys and audits access. If the key prompt doesn’t appear on login, users can press Shift + Option + Return to bring it up manually.

For Macs with FileVault enabled before Intune enrollment, users can manually escrow recovery keys via the Intune Company Portal. This is especially helpful in BYOD scenarios.

“This manual method ensures devices encrypted outside MDM flows can still benefit from secure recovery key escrow.”

Migration and Support

Migrating Macs with existing FileVault encryption to Intune can be tricky. Tools like Netflix’s open-source Escrow Buddy help automate recovery key escrow during migration.

Microsoft also offers extensive community support through the Microsoft Mac Admins LinkedIn group and FastTrack assistance for organizations with 150+ Microsoft 365 licenses.

Final Thoughts

Deploying FileVault with Microsoft Intune is now more straightforward and secure than ever. By using the Settings Catalog and leveraging Platform SSO, enterprises can enforce encryption policies seamlessly.

Remember, FileVault isn’t just about encryption—it’s about integrating security into user workflows without friction. If you’re managing macOS devices in a Microsoft environment, this approach is a must-know.
