Description
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.
