I don't know how to undo what I have done - I had found how to get Lightroom to "see" my pictures which were all in the Photos programme on my MAC with the new Yosemite update. I seem to have doubled up on original pics - so I have them in my Lightroom and Photos programme. So I have folders going back years in both programmes and don't know what to do now - Lightroom doesn't recognise the Photos programme so I did go by Adobe H lap initially but have done something incorrectly. Appreciate any help forthcoming. thanks in advance.
