Vulnerability Discussion

The prompt to set up iCloud storage services during Setup Assistant must be disabled.

The default behavior of macOS is to prompt new users to set up storage in iCloud. Disabling the iCloud storage setup prompt provides organizations more control over the storage of their data.

Check

Verify the macOS system is configured to disable iCloud Storage Setup during Setup Assistant with the following command:

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

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

Fix

Configure the macOS system to disable iCloud Storage Setup during Setup Assistant by installing the "com.apple.SetupAssistant.managed" configuration profile.
