Photos error "an unexpected error occurred attempting to prepare your library"
Hello Everybody,
Today I've updated to the latest version of Yosemite and launched the Photos application. After about 15 minutes, the following error appears when the app is trying to build my photo library: "an unexpected error occurred attempting to prepare your library". Progress didn't go over 30%, even when not selecting to use iCloud Photo Library.
System info: Macbook Pro Mid 2012, Yosemite 10.10.3
Thanks a lot for your help!
Regards,
Fernando
MacBook Pro, OS X Yosemite (10.10.3)
