OK - this may not be for everyone, but, after ******* around with various people's suggestions, I realized that:
a) I still had iPhoto, and
b) I still had Aperture.
I wanted to go back to iPhoto, but I had a whole slew of stuff in Photos that wefren't on iPhoto and I needed in iPhoto. Imagine the tedious process of export/import. Yuck!!! I have to admit I started doing this - with messages that my drive was getting full!!!!
So, Photos will let me export whatever I want to Aperture. Neat. I selected the missing photos from iPhotos in Photos and sent them to Aperture. Aperture shares the iPhoto library, so any changes to Aperture shows up in iPhoto! Easy-peasy!
Now, why didn't "Photos" think of that! I think it's Apple trying to make us do what they want (or think we want) and not what we want! It really is a **** trait of Apple that makes you do what they want you to do and makes as sure as possible you can't get around it easily - if at all!!!
Hope this helps someone - and maybe alerts Apple to its failed mission to provide user-friendly software and apps that are not Windozed!
