Well, I was trying to figure out how to best sync documents between my old 2011 Mac and my new 2015 MB Air and I made the fatal mistake of clicking the box to store my documents in iCloud. Basically, iCloud has taken over my documents. When I try to cancel (still uploading since there is at least 750G in my documents) it says my documents will not be available on my Mac but only on iCloud. I backed up before attempting. Should I just stop the upload, delete what is in iCloud and import my files back in?
