I had a quick search through this forum but couldn't see a post with the same issues. I logged on to my Mac to open a document in iCloud only to find that iCloud was completely empty and all my files had disappeared. I had moved them from my Mac to iCloud three weeks ago. To get the files back I had to restore the files from my Mac using time machine. The only thing I had done since copying the files to iCloud three weeks ago was to reset my iPhone using 'Reset all content and settings'. Surely resetting my phone wouldn't erase iCloud contents. I am running Ios8 and public beta Yosomite Any ideas?
