Photos from iPhone are in iCloud but can't see them in Mac iPhoto
I have turned on Photo Sharing and My PhotoStream in iCloud settings on the Mac, and have turned on iCloud Photo Library (beta), Upload to My Photo Stream, and iCloud Photo Sharing on the iPhone 5s Photos and Camera, and iCloud settings. On my Mac, I do not see the iCloud photos anywhere. From System Preferences I can go to Manage My Storage on iCloud and can see that iCloud contains 309 photos and 8 videos in iCloud Storage in the "Photo Library". That is the same number that were uploaded automatically there from the iPhone.
However, I cannot get to those photos on iCloud from either Finder or iPhoto on my Mac. I am running Yosemite with everything up to date but am a newbie to the Mac and am struggling. From iPhoto I have tried "Import to Library" from the File dropdown but cannot find any location with those photos on iCloud. HELP! What am I missing or not understanding?
