Plan for Change: Intune moving to support macOS 15 and higher later this year

🚨 The Signal: Intune will soon only support macOS 15 (Sequoia) and newer for new device enrollments. Existing devices on older macOS versions will remain enrolled but will not receive updates, potentially increasing vulnerability.

The Impact

Admins and users with older macOS devices are affected, facing increased security risk from unpatched operating systems.

• Admins: Must update device enrollment policies for macOS 15+.
• Users: May need to upgrade macOS devices to maintain Intune support.
• Security Team: Increased risk from unpatched macOS devices if not upgraded.
• IT Support: Potential for increased support requests for macOS upgrades.

The Action

1. Review Intune device reports to identify macOS devices running versions older than 15 (Devices > All devices, filter by macOS).
2. Communicate with users whose macOS devices are running unsupported versions about upgrade requirements.
3. Plan for upgrading or replacing macOS devices that cannot support macOS 15.
4. Update internal documentation regarding supported macOS versions for Intune enrollment.
