You indicate the Nikon 1 J2 camera.
According to the current list at link below, Apple Camera RAW compatibility works with the Nikon 1 J1. No listing for the J2.
You may need to wait for the next Camera RAW compatibility update and hope Apple adds support. Aperture, iPhoto and Preview all use the current version of the Camera RAW compatibility to render RAW files for viewing.
Shooting JPEG could be an option if you like until (and if) support is added.
