Hello,

 

I use Aperture 3.4.3 and I have the following problem. If I import photos in jpg format they are immediately available in the media browser and can therefore be selected as a desktop photo via the Desktop & Screen Saver preference pane. If I import photo's in raw format, they do not appear in the media browser until I have forced Aperture to rebuild the previews. If I edit the photos without forcing Aperture to rebuild the previews they are not available in the media browser.

 

Any suggestions are welcome

MacBook Pro (Retina, Mid 2012), OS X Mountain Lion (10.8.2)

    I think, that is exactly as it is supposed to be. The Media Browser requires previews to share with the iLife and iWork applications. If you do not tell Aperture to create such previews, it will not create them to save space.

    What are your settings in the Previews tab of the preferences? Have you enabled the automatic creation of previews? If not, you will have to force the creation manually.

    There is another setting that applies to raw files:

    Have you checked the "Preferences > Import" panel? Is "camera Previews" or "standard" previews checked? Try to set this to "camera" previews, if it is not already set this way.

     

    If all preferences are o.k., and you still do not see the previews in the Media Browser, try the general trouble shooting routine: The Aperture Library or  or the Aperture preferences file may be corrupted. Start with repairing permissions and repairing the library, then removing the preferences.

     

    See the Aperture 3: Troubleshooting Basics for how to do this.

    Is the problem, that the previews do not show in the Media Browser, or that the previews are not generated. Have you looked into the Aperture library package, if the previews actually are generated? Ctrl-click the Aperture library package, select "Show Package Contents", then look in the "Previews" folder for the missing previews.

    If the previews are there, but the Media Browser does not see them, the problem may not be with Aperture.

    In which application are you using the previews?

    1. Aperture does not generate any previews when importing jpg's, raw photo's or merging libraries even though I have selected New projects automatically generate previews and always share previews with iLife and iWork (I am importing photos into an existing project but I would expect photo previews to be updated automatically in these cases as well). My statement above that Aperture shared jpg's automatically is therefore incorrect.

     

    This looks like your preference settings cannot be stored by Aperture. You write, that you already tried to remove the preferences. You did look in the  "Preferences" folder in your hidden User Library in your Home folder  ~/Library/Preferences/com.apple.Aperture.plist and not in the System Library on your MacintoshHD  /Library/Preferences/com.apple.Aperture.plist, right?

    Also, when removing preferences in Lion an Mt. Lion, it is best to log off and on again after quitting Aperture. Otherwise the removal may not take, because you cannot rely on a "Quit" to remove the process from the caches. Aperture simply may launch again restored from the cache, without noticing that the preferences have ben removed.


    3. If I edit the photo in Aperture after I have generated a preview (say crop it), the preview does not get updated.

    That is consistent with the above.

     

    4.You can only resolve this by forcing Aperture to generate a new preview, shutting down Aperture and then launching the preference pane.

    Ths may also be related to broken Aperture preferences. The Media browser needs the preferences file to find the current Aperture library.

     

    I like to suggest two basic tests:

    1. Generation of previews may also fail, if your Aperture library is corrupted. Then You should have no problems with the generation of previews, when you import into a new library. Create a small new testlibrary and import a few images. Are previews generated? I not, then the problem is not dependent on your current library. If yes, you need to trouble shoot your library. Post back.
    2. Do you have the same problem, when working from a different user account with a diffrent Aperture library? Then preferences are not a problem - you have a system wide problem and probably need to reinstall. Post back.

    Regards

    Dionysis,

    is your main Aperture library in a location different from the one where you put your test library?

    On an external volume, a network volume, a shared folder? Is your library referenced or managed?

     

    Regards

    Léonie
