Hope someone can help. I've been struggling to set up photos app Initially when photos appeared as part of latest update on my mac mini it didn't automatically recognise my iPhoto library and import it. So I tried to do it manually. I have a lot of photos (146k+) so I set the import going and left to run overnight. This morning photos was saying it couldn't import some of my photos (about 144k of them!) saying meta data couldn't be found. I was having problems with iPhoto previously where after yosemite update iPhoto would not display any pictures. I called apple support who managed to talk me through getting my photos back into iPhoto but it was a real mess with lots of duplicates and lots of (what I assumed to be) faces pictures appearing amongst normal events (ie not under the faces section), photos in wrong events etc. Not sure if something has gone wrong or whether just the sheer number of photos and videos is causing an issue. I think there are around 146,000 photos and videos. These are all stored on an external drive due to space. Can anyone make any suggestions of how to see them all so that I can perhaps trim that number down to remove any duplictaes/unwanted pictures?
