Hi all please can someone advise me on the iCloud Photo Library. When I turn it on my recent photo are imported but everything else thats in my photo stream disappears from my collection?! Do I have to leave it 24 hours to transfer across or do I need to save my pictures to my iPhone then turn on ICloud Photo Library on? It's a little confusing and if some can explain in basic terms how it works as I can't find anything on the www that helps, just guides on finding photo stream in collection etc. Thanks in advance, Peter. PS. Is there an iCloud Photo Library App for OS X Yosemite DP or will they just show up in the iCloud Drive folder?
