Using latest Sierra / iOS / iTunes Backing up to computer using cable It starts backing up fine - creating the backup folder in the Library/Apple Support / Mobilesync/Backup It gets to stage 28Th ( as shown in iTunes progress bar ) then hangs with this message: ( see pic ) The backup folder it has created always reaches 2.67gb in size. What can I do? I feel I can't simply go reset my iPad - as I now have no backup file to restore from! Thans!!
