With the new app photos for mac, I'm getting a little confused. I didn't have that many photos in my iPhoto library, and yet it says that it is uploading 4000, where are those photos coming from? Are they coming from the shared photos in my shared photo stream? If so, how do I stop that from happening?
Also, how do I sync the photos from my photo library on my phone, or is that what is already uploading? And I know that they sync between devices but do they sync screenshots and saved photos or only photos that are taken with the phones camera?
