Check Contents

Review configuration settings to confirm "Allow sending diagnostic and usage data to Apple" is disabled.

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

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 sending diagnostic and usage data to Apple" is unchecked.

Alternatively, verify the text "<key>allowDiagnosticSubmission</key><false/>" appears in the configuration profile (.mobileconfig file).

On the Apple iOS device:
1. Open the Settings app.
2. Tap "General".
3. Tap "Profiles & Device Management" or "Profiles".
4. Tap the Configuration Profile from the iOS management tool containing the management policy.
5. Tap "Restrictions".
6. Verify "Diagnostic submission not allowed"

Note: This setting also disables "Share With App Developers".

If "Allow sending diagnostic and usage data to Apple" is checked in the iOS management tool, "<key>allowDiagnosticSubmission</key><true/>" appears in the configuration profile, or the restrictions policy on the Apple iOS device from the Apple iOS management tool does not list "Diagnostic submission not allowed", this is a finding.
