Shared photos/videos not appearing in streamson originating imac, only icloud icon
I share pictures and photos to icloud from Aperture 3.5.1. The photos and videos are available on other devices that share the same icloud stream, but in Aperture on the originating imac, when I look in the "icloud" section at the photo streams, I see the streams, as named by me, but I don't see the actual shared photos oir videos, only an icloud icon. Again, the other devices see the streams and photos fine. Only on the originating imac is there a problem. If I share a photo or video from one of the other devices onto icloud, the imac can access the item with no problem. It's only this one aspect of sharing from the imac that's giving me problems. Any insight?
iMac (21.5-inch Late 2009), OS X Mavericks (10.9.2), Aperture 3.5.1
