To me, the problem is not iCloud being opaque, but that it&#x27;s been unreliable at best, and a migraine-causing frustration at times. For example, some years ago when Apple rolled out syncing bookmarks across your macs and iDevices, I managed to completely destroy how my bookmarks were organized on both the source (mac) and the destination (ipad). iCloud in its infinite wisdom decided that it didn&#x27;t like the way I had organized bookmarks into folders and subfolders, and tossed everything up to the top level.<p>Syncing documents across pages or keynote across my mac and ipad were about as bad as the article described. It would take multiple refreshes and delays before synchronization would happen.
