I need help I have 3 mac's and I have discovered my photos are an absolute mess.
I am a avid photographer who used to separate my photos from my family. I used aperture and they used iPhoto.. I have merged to Lightroom and they moved to Photos.
Unfortunately my libraries are a mess mainly because my children have decided to create multiple photo libraries and place them everywhere.
I have 8 on one mac. 4 on another. It is quite likely there are thousands of duplicates. How do I merge all the 12 photo and iPhoto libraries and then delete the duplicates. It also is likely that the merged library would be too large on the hard drive of 1 mac, so I assume I would move them all to an external hard drive. There is significant meta data in most of these libraries so I don't want to loose these.
