iCloud Photo duplication
I am running macOS Monterey. I was able to run a program provided by apple to find and delete duplicates. I can’t find that on this version, why?

Question marked as
Duplicate detection was introduced to Photos with Ventura. Apple has not had another duplicate detection system to work with Photos or otherwise.
Before Ventura, ,to deal with duplicates, many people used the 3rd party app, PowerPhotos ($30), one of the very few apps that we can trust to work properly with Photos. I still use it sometimes-- different algorithms give slightly different results, and it's useful to double check. If you must stick with Monterey, then PowerPhotos (which has been trusted for 20 years) adds great utility for Photos.
