iPhoto not opening after Yosemite opens through App Store
I updated iPhoto to 9.6 and then upgraded to Yosemite. iPhoto now shows as an invalid icon; when I click on it, I get the message "in order to open iPhoto you need to update to the latest version, the version of iPhoto installed on this Mac is not compatible with Yosemite". It then tells me to search the App Store.
I do have the latest version of iPhoto. When I go to the App Store after hitting the "search" option from the error message to download it again, instead of the "install" button there is an "open" button that then opens iPhoto normally. But I can't open iPhoto unless I do it from the App Store button.
Any ideas?
OS X Yosemite (10.10)
