I am trying to convert to Photos. When I started Photos it moved my iPhoto photos to Photos. It was a mess. But I think it will improve. I do not use events, just albums and I think that is the problem. But, the question.. If I add photos to iPhoto as time goes on, (I keep using it because I understand it), how do I progressively update the photos library ? I ask because one day I know that Apple will "force" me into Photos exclusively. Many thanks for any ideas.
