Q: how do I delete a shared photo stream?

thanks Joe but I don't see an explanation on removing it in Photos on a Mac.

as you can see from the screen grab, I have two shared albums called "Family" and am trying to delete the empty one, and there isn't an obvious way of doing that in Photos.

I only get "Play slideshow" as an option when I Ctrl-Click

I just tried Cntrl-Click on the shared album that has photos and the "Delete" option does come up, wonder why it doesn't come up on the one that's empty..

having trouble moving photos there, I seem to recall reading something about this on the web when migrating to Photos, I think it was related to something about turning on sharing which I shouldn't have...
