RAW format Problem with NIKON D600 after updating to maverick.

We still have problems after this update.

Pictures in RAW format imported to Aperture are brilliant as they are with the NIKON D600. Imported Pictures with the NIKON D800 are aweful. They are kind of grey without any saturation. To convert every single Picture to JPEG brings back their brilliance and colors. We have consulted the apple and the aperture support, but they dind't have any solution to fix our issue.

Any ideas?
