Q: When I set up Photos on my Mac I chose my Aperture Library. Now there is no photos in Photos or Aperture! They are all in the Photos Library but I don't know why they aren't in Photos when I open it???

Hi Larry, I upgraded to El Capitan so I could update to Aperture 3.6 because my new Canon EOS 80D raw images wouldn't open in my older version of Aperture. I then decided to start using Photos (1.5), during the set up it asked me to nominate a photo library ( i have an older iPhoto library). I chose my Aperture library. All my photos are on my Mac HD in a Photos Library (400 GB......I have a lot of photos). But when I open Photos I get the Welcome to Photos page. Do I need to import the Photos Library into Photos as there are no images showing? Cheers

Dear Larry, thx again for the prompt reply. I tried that and got the message that 'The content of The "Aperture Library" has already been migrated to Photos. Open Photos to view your library or use a compatible version of Aperture to open this Aperture Library.' I selected the Open Photos button but alas there are no images in Photos!?

I managed to import a single image that wasn't in the Aperture library OK. That removed  the welcome page. I deleted the image and got the welcome page back. I should mention there was an electricity blackout when the photos were migrating but as previously mentioned they seem to be in the Photos Library folder on my HD. I can still access them if I open the folder in Aperture but not in Photos?

All sorted after following your advice , thank you Larry!
