Removed Over 2 Gigs
I looked for many apps to help me deduplicate my collections in Photos. While I did not want to pay for an app, it seemed like the free apps were not trustworthy. I decided that PhotoSweeper was the best option and it successfully found all the duplicates I knew were there. In the end, I removed nearly 3 gigs of photo data. Worth it.
