It works with the built-in Photos app, as well as iPhoto, if you haven't yet migrated your library. It is designed to find duplicate and similar photos based on such parameters as size, aspect ratio, length of time between shots, file names, bitmaps or histograms, and more.

If your biggest problem is too many duplicate pictures stored on your Mac, PhotoSweeper is great for weeding out the extras so you can free up space.

It is perfect for people that feel comfortable making changes to their computer and want the ability to deeply control the types of files that a duplicate finder searches for. Tidy Up is an extraordinarily versatile duplicate finder. Items found can be trashed, moved to a different folder, or copied to a disc or jump drive. For example, you could ask it to check images that were taken on the same date, location, or pixel size. Or, you can use Advanced Mode, which gives you control over specific items you want to check as a duplicate or needing removal. You can use Simple Mode, which does a basic search of predefined criteria. Tidy Up utilizes two ways to scan your computer. So, if you've got a bunch of temporary files cached in your hard drive, Tidy Up will suss them out and give you the option to trash them if you don't need them. It scans your computer for copies of file types and folders in your local and external hard drives. Tidy Up finds duplicate files in your Photos, iPhotos, Aperture, iTunes, and Mail apps on Mac.
