Recently I upgraded my macbook from Yosemite to El Capitan. I noticed in iphoto photostream, it had to rebuild the entire library. I currently have 290 photos in photostream which I can see in my iphone, but on the mac, iphoto downloaded only the newest 250 photos. Is there any way to force iphoto to download the oldest 40 photos? If not, is there a simple way to download these 40 photos to my mac? They are not in the camera roll or an album on the phone. Thanks.
