The macOS system must disable iPhone Mirroring.

Rule version APPL-26-002271 · STIG v1 · 2026-09-01

Discussion

iPhone Mirroring must be disabled to prevent file transfers to or from unauthorized devices.

Disabling iPhone Mirroring also prevents potentially unauthorized applications from appearing as if they are installed on the Mac.

Check

Verify the macOS system is configured to disable iPhone Mirroring with the following command:

/usr/bin/osascript -l JavaScript << EOS $.NSUserDefaults.alloc.initWithSuiteName('com.apple.applicationaccess')\ .objectForKey('allowiPhoneMirroring').js EOS

If the result is not "false", this is a finding.

Fix

Configure the macOS system to disable iPhone Mirroring by installing the "com.apple.applicationaccess" configuration profile.
