iCloud Drive is another epic FAIL by Apple in an attempt to provide any reasonably dependable cloud syncing services, go figure! Last month when Yosemite was released, I signed up for 300 gb of storage and added 70+ GB to my iCloud Drive folder which I just wanted to keep synced between 2 Macs. It took forever to sync, as a matter if fact, Im not sure it EVER did fully sync. I have Xfinity (Comcast) as my ISP and as most are aware, they have a 300 GB a month Bandwidth limit. I have never exceded it, and normally do go over 200 GB a month (and I don't use Netflix or any other streaming/download movie services). I started getting warning from Comcast that I was reaching my limit and then i went over my limit, and eventually by the end of the month, I used over 800 GB of bandwidth. Then, 2 days into the new month, I had used over 50% of my monthly limit, Im like WTF! I decided to turn off iCloud drive and the problem was resolved. So I decided stop syncing that 70+ GB of data, move my data to a different drive/folder and deleted it from my iClould drive in Finder thinking it was gone but no! It's still on the cloud. Anytime I turn on iCloud Drive back on it wants to eat up my bandwidth again and start syncing that data. I finally just had to turn off iCloud Drive on all of my computers/devices and contacted Apple. They couldn't even delete the files on the cloud. They put my account in troubleshooting mode and it's been almost 2 weeks now and Im still waiting for them to fix this issue. At this point I just what them to delete those documents so I can turn iCloud Drive back on so the applications that use iCloud Drive can sync its data, but at this point in time, I can't use those applications because I can't turn iCloud Drive back on, not if I want any bandwidth left for the rest of the month. Im so dissipointed in Apple, they have totally screwed up with iCloud Drive! What a shame, I really thought they would get it right this time, but they just can't seem to get a clue how to make this service work. Maybe they need to buy DropBox and or SugarSync so they will have someone smart enough to fix it!
