If I update my iphoto library are my photos in danger?
I updated my macbook with a maverick and iPhoto was no longer working so I updated to the latest iPhoto as well. Now when I try to open iPhoto it gives me this message: "Your photo library will not be readable by previous versions of iPhoto after the upgrade" and then just something about how large libraries may take up to an hour to upgrade. It sounds alright but I just wanted to make sure, will my photos and videos be safe if I proceed with the upgrade?
