I would not recommend using this app with Aperture
It will screw up the paths to your photos and the only way I was able to find the lost photos was to run this app again which takes FOREVER!!!!! and then use the show in finder option. I couldn’t find a way to resolve the paths to the photos with Aperture after using this app. Very frustrating, Aperture is very frustrating anyway and this makes it that much more FRUSTRATING!!!! I gave it a star because it’s required.
