The App neither recognize my Photo Library nor delete anything

I spend some good time on the app to figure out why it does not recognize my library, or delete any duplicate found. I think the app only support iPhoto, not the newer version Photos in most MacOS nowadays. Very disappointed! NOw i know why the app discount from $20 to $0.99

It is not compatible to newer OS Photos App, don’t buy
