I cannot open iPhoto now that I upgraded to Yosemite.When I click iPhoto it says I have to download older version of iPhoto.The app store, it says "The item you've requested is not currently available in the U.S. HELP!

This was frustrating the **** out of me and I had three sessions on the phone with apple support and nothing. This is what ended up helping me. Simple

1: Connect your external hard drive to new Mac

2: Open Photos on new Mac

3: Open 'Users' in hard drive and select user with iphoto library

4: Right click on iphoto library in your pictures folder and select 'open package contents'

5: Find the master folder and drag it into photos

Done. Only thing you will have to reorganise your albums because there wont be any. Why couldnt apple tell me this. Two weeks I was frustrated!! haha oh well.

Apart from the irrelevance of your post to this topic, you really must want people when your 'solution' to whatever problem you have means any dataloss, not to mind massive amounts of dataloss.
