Issue Status: RESOLVED

Issue Description: Devices that are updated to MacOS version 15.0 see that devices are non-compliant.

More info: Specifically, the Stealth mode Firewall setting on devices is being reported as False when it was initially reflecting as True, prior to the update. Admins will see under MacOS policy setting compliance that the Stealth mode setting state shows, “Error, Remediation failed”.

This impact only occurs when both the “Mac Firewall Stealth Mode policy” and the “Block all incoming” policies are enabled, and admins can remove the “Mac Firewall Stealth Mode policy” to remediate the impact.

Final Update: 24/09/2024 08:57:00 AM –Microsoft have confirmed that the impact only occurs when the “Mac Firewall Stealth Mode policy” and the “Block all incoming” are enabled. They determined that these are both enabled in the environment managed by your organization and is causing the problem in which devices updated to MacOS version 15.0 are showing as non-compliant. They recommend disabling the “Mac Firewall Stealth Mode policy” to resolve the issue. The Microsoft-managed environment is functioning as expected and a service incident didn’t occur. This communication will expire in 24 hours.
