Aperture 3.2: Deleting from Photo Stream does not work after upgrading to OS X Mountain Lion
Deleting an image from Photo Stream in Aperture removes the photo from Aperture's Photo Stream view, but does not remove it from Photo Stream on other devices.
Aperture 3.3 or later is required to delete images from Photo Stream on OS X v10.8 Mountain Lion.
To update Aperture 3.x to the most recent version:
- Choose Software Update from the Apple () menu.
- Install Aperture from the list of available updates.
