I cannot open Photo. It says The application “Photos.app” is not open anymore.
I upgraded my Imac to Yosemite and cannot upload any of my pictures to the new app "Photo". I have tried multiple times to do this, but it refuses to even acknowledge my iphone 6 plus anymore when I plug it in. It pretends to upload after many attempts and then it fails. In the meantime, I use my iphone to take pictures and videos and its getting all filled up with data and I cannot dump it anywhere. I was finally able to dump some pictures into a flash drive, but then "photo" just crashed and I cannot reopen to delete old pictures in my Imac. Its a real mess. I've been dealing with this problem for over 2 months. I finally took it to an Icare in Thailand to fix and they cannot help me. (I live in Laos) . I'm thinking of turning back to Pc. I think they want me to buy into Icloud which I do not want to do. this is my punishment.
