If you also prefer to remove duplicate images on mac for mac cleaning, which program or service do you use to delete duplicate photos?
I collect a list of top duplicate photo finder for mac according to Google search:
1.dupeGuru
2.Cisdem Duplicate Finder
3.Duplicate Photo Cleaner
4.Photos Duplicate Cleaner
5.Duplicate Photos Fixer Pro
6.Photosweeper 3

Also, you can find the results pages:

https://www.macworld.com/article/3195031/photography/photosweeper-3-review-sorts-out-the-image-duplicates-in-your-macs-media-libraries-and-folders.html

I tried all them, they all worked on my mac, so i am confused which one should I invest.
