Discussion

The macOS system's ability to automatically synchronize a user's Desktop and Documents folder to their iCloud Drive must be disabled. Apple's iCloud service does not provide an organization with enough control over the storage and access of data and, therefore, automated file synchronization must be controlled by an organization-approved service.

Check Content

Verify the macOS system is configured to disable iCloud Desktop and Document folder synchronization with the following command:

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

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

Fix Text

Configure the macOS system to disable iCloud Desktop and Document folder synchronization by installing the "com.apple.applicationaccess" configuration profile.
