STIG ID: APPL-26-005054 | SRG: SRG-OS-000095-GPOS-00049 | Severity: Medium | CCI: CCI-000381 | Vulnerability ID: V-277169

Description

The prompt for TouchID during Setup Assistant must be disabled.

macOS prompts new users through enabling TouchID during Setup Assistant; this is not essential and, therefore, must be disabled to prevent the risk of individuals electing to enable TouchID to override organizationwide settings.

Check

Verify the macOS system is configured to disable the TouchID 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("Biometric")
EOS

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