Hello, I have never used I-cloud before and I am confused by all the info I have googled. I have an i-mac and 96 000 photos in Photo Libray. As I am travelling more and more and thus not having access to my I-Mac, I have bought a Macbook Pro. What I would like is to be able to access my photo library through i-cloud from my Macbook Pro when travelling . I want to keep the originals on the i-Mac and I don't want the photos to download automatically to my Macbook pro, because it is not necessary and I don't have enough memory. Is that possible and how ? Thank you
