Photo Stream STOPPED on desktop; OK on other devices
My Desktop Mac stopped adding photos in its Photo Stream a couple days (weeks?) back even as my other devices (iPhone, iPad, etc.) are updating their Photo Streams just fine.
I turned OFF iCloud in System Preferences, and turned OFF Photo Stream in iPhoto; rebooted; and reactivated both to no avail.
In my photostreams window, I can see the names of shared Photo Streams that were there previously, but they are all empty.
Any ideas?
