How can i delete duplicated photos?
MacBook Pro (13-inch Early 2011), iOS 8.0.2
Just delete them. The Mac App Store has apps that will scan for duplicates and offer to delete them. I have used Duplicate Cleaner for iPhoto and Photos Duplicate Cleaner
Photos is detecting duplicate image files when you import photos to to Photos and give a warning. If you import the duplicates nevertheless, you are on your own. Photos has no tools to find them. You can sort the photos by the date, so duplicates will appear side-by-side and are easier to spot, but that's it.
If you shop for duplicate cleaners, stay away from applications that will modify the Photos Library directly. Only use tools that move the duplicates to the recently Deleted album or collect them in an album. Some Duplicate cleaners will modify the library and can corrupt it, for example CleanMyMac.
Photo Sweeper is safe, Power Photos, Duplicate Annihilator.
Photo Sweeper can find duplicate photos in different states of edits or sizes. It is very versatile.
Power Photos is a great tool to have, if you are using multiple Photo Libraries, because it can find duplicates across libraries, merge libraries, and let's you browse Photos Libraries in list view with metadata added.
These applications will identify and help remove duplicate photos from an iPhoto Library:
iPhoto Library Manager - $29.95
PhotoSweeper - $9.95 - This app can search by comparing the image's bitmaps or histograms thus finding duplicates with different file names and dates.
Duplicate Annihilator - $7.95 - only app able to detect duplicate thumbnail files or faces files when an iPhoto 8 or earlier library has been imported the library.
DeCloner - $19.95 - can find duplicates in iPhoto Libraries or in folders on the HD.
DupliFinder - $7 - shows which events the photos are in.
iPhoto AppleScript to Remove Duplicates - Free
PhotoDedupo - $4.99 (App Store) - this app has a "similar" search feature which is like PhotoSweeper's bitmap comparison. It found all duplicates
Duplicate Cleaner for iPhoto - free - was able to recognize the duplicated HDR and normal files from an iPhone shooting in HDR
Some users have reported that PhotoSweeper did the best in finding all of the dups in their library: iphoto has duplicated many photos, how...: Apple Support Communities.
If you have an iPhone and have it set to keep the normal photo when shooting HDR photos the two image files that are created will be duplicates in a manner of speaking (same image) but there are only twp apps that detected the iPhone HDR and normal photos as being duplicates: PhotoSweeper and Duplicate Cleaner for iPhoto. None of the other apps detected those two files as being duplicates as they look for file name as well as other attributes and the two files from the iPhone have different file names.
iPLM, however, is the best all around iPhoto utility as it can do so much more than just find duplicates. IMO it's a must have tool if using iPhoto. Purchasing it at this time qualifies you for a license for PowerTools, the iPLM equivalent for the new Photos app.
This is a very helpful answer. Thank you. They appear to relate to iPhoto. Do the recommendations apply to Photo?
I appear to have two libraries on my system : iPhoto and Photo. Is it necessary or helpful to keep them both, now that I have upgraded to Photo?
I also appear to have triple or even quadruple versions of my photos after upgrade which has really slowed my iMac down when Photos is open. What else do I need to do apart from eliminate duplicates to speed things up.
These applications will identify and help remove duplicate photos from a Photos Library:
PowerPhotos is the iPhoto Library Manager version for Photos and is very powerful. Although more expensive I would recommend it as it has more capabilities than the others like the capability to merge Photos libraries or copy photos along with their metadata between libraries.
