Catalina - Disable iCloud Document Sync

Information

The macOS built-in iCloud document synchronization service _MUST_ be disabled to prevent organizational data from being synchronized to personal or non-approved storage.

Apple's iCloud service does not provide an organization with enough control over the storage and access of data and, therefore, automated document synchronization _MUST_ be controlled by an organization approved service.

Solution

This is implemented by a Configuration Profile.

allowCloudDocumentSync:
False
