Hello guys. I am running Photos for Mac on OS X 10.10.5 for my photo organization needs. I import my photos from my iPhone and over time, organize them into proper folders. I then delete each photo from the last import to know which ones I have already organized. Stupid me, I dropped in a single photo and lost my lost last import I was working on. Is there a quick access to a last import history to bring back the previous import structure I was working in? Thanks!
