Vulnerability discussion

The prompt for Apple ID and iCloud must be disabled, as it might mislead new users into creating unwanted Apple IDs and iCloud storage accounts upon their first logon.

Check content

To check if the system is configured to skip cloud setup, run the following command: /usr/sbin/system_profiler SPConfigurationProfileDataType | /usr/bin/grep SkipCloudSetup If “SkipCloudSetup" is not set to "1", this is a finding. To check if the prompt for "Apple ID" and "iCloud" are disabled for new users, run the following command: /usr/bin/sudo /usr/bin/defaults read /System/Library/User\ Template/English.lproj/Library/Preferences/com.apple.SetupAssistant If there is no result, if it prints out that the domain "does not exist", or the results do not include "DidSeeCloudSetup = 1 AND LastSeenCloudProductVersion = 10.12", this is a finding.

Fix text

This setting is enforced using the “Login Window Policy" configuration profile.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
