Hi Guys, Trying to find the best way to get rid of thousands of duplicate photos that I have collected over the years. I have been using an iPhone since 2008 and backing up photos to different methods over the years (Dropbox, iTunes, Google Drive and iCloud in later years) now I also have a MacBook Pro running Yosemite 10.10 and have decided to go through and consolidate all my photos. I have downloaded all the photos from all the online shares and imported everything into iPhoto. Problem is because files have changed names over the years somehow I have no real way of finding duplicates. Im looking for recommendations on how I could find and get rid of these duplicate files maybe with the use of meta data and also any recommendation of how to best organise and sort the photos?
