My iMac transferred over a GB of data and I can't figure out what it was or why it transferred it as was not present. There should not have been any kind of update at 9:28 PM, especially that large with no permission. I can't find any kind of Dropbox or Evernote sync or anything that makes sense. I have a limited data plan and can afford this kind of occurrence. HELP!!!!
Got a tip for us?
