Help. My photos were just over-written by my wife's!
I just opened iPhoto (I haven't upgraded to Photos yet, so that's not the issue), and several years worth of my photos (though not quite all of them) have been overwritten by my wife's photos. She just did a major system upgrade, so I suspect that was the root cause. What happened? Is there any way to recover my photos?
We do photo-sharing via iCloud.
