iCloud -- controlling what it holds
How do I stop iCloud from uploading ALL my documents and data?? I Clicked "documents and desktop" because I thought that merely enabled my ability to upload my choice of documents. But it is uploading EVERYTHING! Burned through my data cap! I had to disconnect wifi. Now I want out of iCloud, but I'm afraid it won't give me my documents back. Some of them have dotted-line clouds--does that mean they are still on my computer? Will I have to spend $$$ on data to get my documents downloaded to my computer again? HELP!!!
