Did you mean mac os x 10.6.8 Snow Leopard?
Anyway you can try Help>Updates from within photoshop cs6 to get the appropriate camera raw version.
For mac os x 10.6.8 and photoshop cs6 that would be 8.3
For windows 7 and photoshop cs6 that would be 9.1.1
If Help>Updates doesn't work you get the camera raw installers from here:
Camera Raw 9.1.1 for windows 7
Camera Raw 8.3 for mac os x snow leopard
Mahalo for your speedy reply and suggestions, and yes 10.6.8
I tried update but in
- Filter - distortion CS6 knows a D90, but not D7000, D7100, D7200
Most likely, especially with nikon, the specific camera model isn't listed, but one uses the lens model instead.
Thank you! Good to know, just confusing due to many older specific camera models D300, D300 s and more are listed.
