Photos App – Problems with Duplicate Photos on Photos App

I wrote a $7 app called Duplifinder that finds and shows duplicates in your iPhoto Library: http://www.haystacksoftware.com/duplifinder/

You can view the sets of duplicates, double-click to locate a photo in iPhoto, press Delete to delete a photo from iPhoto. Or just push "Move all duplicates to iPhoto Trash" to clean up.

If you have any questions about it please email me at support@haystacksoftware.com. - Stefan

The best procedure is to one by one, turn off each cloud sync source of contacts.

They will remain in the cloud and be removed one by one from your iPhone.

When you have all cloud accounts turned off as far as injecting contacts into the contact app, you will be left with only the local groups and contacts stored on the device itself. If you don't wish to have a local contact on the phone, sync and delete these from a computer (or manually from the device).

At that point, re-establish the cloud sync for each account - checking that there are no duplicates after each addition.

Once you have eliminated the possibility of duplicates locally vs. cloud - you can quite easily clean up the cloud source of duplicates if needed.
