Just migrated across to new iMac OS X 10.9.3 and now iPhoto responding with "Photo Library needs to be upgraded" when I click Upgrade it just sends me back to Home screen with no upgrade process being triggered? How do I fix this so I can launch iPhoto? just want to complete the upgrade ?
iMac (21.5-inch, Mid 2014), OS X Mavericks (10.9.3)
Thanks Eric - I tried this process and selected the option to "Rebuild" - it comes up with an "Upgrade" button which I click and then it flashes up "Examining photo library" and then quits iPhoto and back to home screen with no progress. Same problem I was encountering the first time. I have also now upgraded the OS to Yosemite and it gives the same responses. Help???
You are welcome. I'll ask the hosts to transfer this post to the iPhoto community where you will likely get better help.
