Q: I recently updated to OS 10.9 and updated aperture to 3.4.3 from 3.2.4. Now I have no adjustments available form the add adjustment bar. How do I get all the options back?

Are there no adjustment presets at all, or are your custom adjustments missing? The layout of the panels chnaged between versions. Your own custem presets have moved to the  "Effects" menu.

If all adjustment presests are missing, you may have a problem with a corrupted preferences file. Then quit Aperture and try,if removing the preferences will help, as described in this support document:

Aperture 3: Troubleshooting Basics

Delete the user preferences

You can resolve many issues by restoring Aperture back to its original settings. This will not impact your image files or your library. To reset your Aperture user preference settings to their original state, do the following:

1. Quit Aperture.
2. In the Finder choose Go to folder from the Go menu.
3. Type ~/Library/Preferences in the "Go to the folder" field. Press the Go button.
4. Remove the "com.apple.Aperture.plist" file from the Preferences folder.
5. Restart your computer if you're using OS X Mavericks.

Note: The locations of your Aperture libraries are stored in the preference file listed above. If you have stored your library outside the default location of  ~/Pictures/Aperture Library, make a note of where the library is before deleting the Aperture preferences file. If you have more than one library, you can bring up a dialog to choose which one to load by pressing Option immediately after you open Aperture.
