Ad tracking and targeted ads must be disabled.

The information system must be configured to provide only essential capabilities. Disabling ad tracking ensures that applications and advertisers are unable to track users' interests and deliver targeted advertisements.

Check

Verify the macOS system is configured to disable personalized advertising with the following command:

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

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

Fix

Configure the macOS system to disable personalized advertising by installing the "com.apple.applicationaccess" configuration profile.
