Aperture: Elements of user interface do not match language setting

Issue or symptom

After you change the language in the International preference pane to one of the supported languages in Aperture 1.5, Aperture's keyword button sets, Metadata Overlays, and Metadata pull-down menu retain the previous language. Also, the Viewer list view shows only the Version name for each image. These issues also occur when updating from Aperture 1.0/1.1 to 1.5 on a German, French or Japanese system.

Solution

Aperture does not overwrite existing keyword button sets when you upgrade or change the system language, to protect any custom sets you may have created. To reset the keyword button sets to the defaults using the current language setting, do this:

1. Quit Aperture if it's running.
2. Go to ~/Library/Preferences/ (where "~" represents your home folder).
3. Drag the com.apple.Aperture.plist file to the Trash.
4. Go to ~/Library/Application Support/Aperture.
5. Drag the contents of ~/Library/Application Support/Aperture to the Trash.
6. Open Aperture.

Note that you will lose any custom keyword button sets you have created, but any keywords already applied to images will remain.
