This is currently the case. Apple released an update to the Leopard (10.5) operating system to add support for the newest Pentax camera RAW files, but this apparently will not work with the latest firmware for the K20D. Hopefully, a future update from Apple will fix it. I have my K20D set to record both JPEG and DNG; I have no problem with the DNG files in Aperture (2.1.1) or iPhoto '08.
