Discussion

The prompt for Screen Time setup during Setup Assistant must be disabled. Enabling any service increases the attack surface for an intruder. By disabling unnecessary services, the attack surface is minimized.

Check Content

Verify the macOS system is configured to disable the Screen Time prompt during Setup Assistant with the following command:

/usr/bin/osascript -l JavaScript 2>/dev/null << EOS
$.NSUserDefaults.alloc.initWithSuiteName('com.apple.SetupAssistant.managed')\
.objectForKey('SkipSetupItems').containsObject("ScreenTime")
EOS

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

Fix Text

Configure the macOS system to disable the Screen Time prompt during Setup Assistant by installing the "com.apple.SetupAssistant.managed" configuration profile.
