Aperture not updating photostream
You can also choose which photos you want to download from Photo Stream into Aperture, as well as the specific photos in your Aperture library that you want to upload to Photo Stream.
i Cloud Photo Library in it's current form will save all your photos and videos to the cloud and is limited only by your current available i Cloud storage.Photo Stream will save the last 30 days of your photos to the cloud (or last 1,000 pictures, whichever is greater), it did not count against i Cloud storage and Photo Stream did not save videos.The biggest advantage of Photo Stream is its compatibility across all devices, including Mac.You'll also need OS X 10.7.2 or later, and i OS 5 on your i Phone, i Pad, or i Pod touch.You'll also need to go to the i Cloud pane in your System Preferences and make sure that "Photo Stream" is ticked (thanks to commenter 'kootenayredneck' for the reminder). This is Photo Stream's marquee feature: snap a photo with your i OS device and have it show up on your Mac.Photo Stream will disappear next year at some point, along with the death of Aperture and i Photo for Mac which Apple has announced it is discontinuing.
If users choose to leave i Cloud Photo Library off, the old Photo Stream paradigm will stay in place.
Photos will sync between your i OS devices like Photo Stream, but do not show up in i Photo or Aperture on the Mac.
Users can access their i Cloud Photo library via the web at i and even upload photos from the web interface.
However, I've also run into cases where Aperture's Photo Stream folder lags in showing recent images.
When this happens I've been able to fix the issue by disabling and then re-enabling Photo Stream in Aperture's settings.
Hopefully, this article will answer all your questions about how these two products interact.
