Does anyone here know how to prevent the Shared Photo Stream badge from showing on the iPhoto icon in my dock? I've disabled "Badge app icon" in Notification settings, but it has no effect. I check the Shared Photo Streams on my iPhone and iPad and don't need to see the badge on my iMac as well (and actually, I thought that Mavericks was supposed to bring notification syncing to the Mac - this iMac is running Mavericks and the iDevices are all on iOS7) ... Anyway, does anyone know how to kill the stupid badge?
