I previously had just iPhoto but purchased aperture 3.3. I am using the unified library on mountain lion now. I did not/do not have any separate aperture library, so aperture is only looking at my “iphoto” library at this point. All is working fine so far but I cannot figure out sharing to other apps via Aperture.
Example: if I go to iTunes–>Advanced–>choose photos to share and choose Aperture it will tell me it cannot find the library. I have previews enabled, and whenever I close Aperture it tells me it is updating previews or some such. As a test I created a new dummy library within aperture with 1 photo. This is recognized.
Similarly, if I go to iMovie in the video source pane there is a new “Aperture videos” above iPhoto Videos, and in the photo browser there is also Aperture as a source, but both are empty whenever Aperture is pointed at the iPhoto library. If I choose the dummy library then that appears to work.
So it seems then that even though both programs use the same library, other iLife apps/Media browser only think that iPhoto “owns” it. My question is whether this is expected behavior? Thanks for any help!
