So I have tried it all. I have removed my iCloud account all together from the new MacBook. I have added another profile to see if that changed anything. I have downloaded Cirrus and tried that. I have created a new document and watched it upload to my iCloud with no issues. I still cannot get the sync to work at all essentially. I have gig download speeds and running all those tests show that I am truly receiving 900+mbps down. So what gives? How could Apple miss this?? All of my work and company documents are synced with my iCloud, so if I cannot get this to sync, then this new $2500 Air is worthless. Any advice or tips?
