After downloading Yosemite, I can't open my iPhoto!!! Please help me!!!
I just downloaded Yosemite a few days ago and noticed that my iPhoto is not working. The message that comes up is "Your photo library will not be readable by previous versions of iPhoto after the upgrade. The upgrade process for very large libraries may take an hour or more to complete." so I waited for it to load but five hour later, it was not updated. Tried a few more times but it would not download and kept on telling me the same message. I don't know what to do and I'm getting frustrated. I need your help.
