i backup my phone to my mac and heaps of my old photos came back and now i can't delete them HELP?!
i can't delete my photos after contacting to my mac
Do you mean, you connected the iPhone to your mac and imported the photos to iPhoto or the Photos.app? And the import panel does not let you delete the photos from your device after importing?
Then you have probably iCloud Photo Library Beta enabled on the phone. In that case you have to delete the photos directly on the device and cannot delete them from the import panel.
