Check Content

This check procedure is performed on the device management tool and the iPhone.

Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review.

In the iOS management tool, verify "Allow iPhone Mirroring (supervised only)" is unchecked.

On the iPhone:
1. Open the Settings app.
2. Tap "General".
3. Tap "Airplay and Continuity". 
4. Tap "iPhone Mirroring".
4. Verify no Macs are listed, or the option is grayed out.

If "Allow iPhone Mirroring" is not disabled in the management tool or iPhone Mirroring is available for Macs on the iPhone, this is a finding.

Fix Text

Install a configuration profile to disable iPhone Mirroring on Mac. This is a supervised-only control.
