Q: Photos duplicates & wrong thumbnails after upgrade
So I finally got around installing Yosemite and now I'm starting to regret it. I have a library of maybe 10'000 photos that I used to store in iPhoto. After the Yosemite upgrade, my mac worked around the clock with the processing of the photos to move them to Photos or whatever it did (100% CPU use for maybe 6 hours).
Now however, I'm going to explain the really scary problems that I'm experiencing:
1. When walking through my library in the Photos-app, maybe 20-30 % of all photos (especially newly imported just before I switched OS) have either wrong or really messed up thumbnails. The photos seems OK first I open them, but I never know which photo I will open because the thumbnail is from a completely different picture.
2. Some pictures are now duplicate, with the exact same file name and file size. I'm afraid to remove them as I fear that it's actually another picture hiding behind the duplicate one that is showing? This is extremely frustrating.
My tries to solve the problems:
1. I have tried to remake the iPhoto events to Photos albums, did not change a thing.
2. I have tried to manually rotate photos to correct the thumbnails. Works 90 % of the time but I'm guessing I have thousands of mixed and faulty thumbnails so that's not really an option.
3. Repairing the library with the option+command control. Didn't change a thing.
What I haven't tried yet:
1. Using a duplicate finder tool. Mainly because I'm afraid to remove photos and because I don't know any good free one.
2. Smashing the laptop in the wall.

And yes I have a backup on TimeMachine, though I had to delete the old Mavericks one because the new Yosemite was too big to fit.
