10.10.3 Yosemite is out, bringing with it Apple’s new Photos for Mac and its associated iCloud Photo Library, which was previously in beta testing. Although Apple has posted an iCloud Photo Library FAQ, it doesn’t answer many of the questions that users have raised. That’s why Joe Kissell took on that chore, compiling a list of those questions and the answers to them in his iCloud Photo Library: The Missing FAQ, published on TidBITS. If you want to know about the system requirements, how much it costs to use, whether you can share the photos in it with family members, how it differs from My Photo Stream, how the iCloud Photo Library affects photo syncing to your iOS devices via iTunes, and much more, check it out.
