Adobe photoshop cs6 not upgrading raw plugins in my macbook i tried to install raw camera plugin in my adobe photoshop cs6, but still not getting installed.
It will depend what version of CameraRAW you are trying to install.

CS6 is no longer supported &amp; the last version it is capable of handling is CameraRAW 9.1.1

For a workaround using DNG Converter, see Update to camera support policy in CS6
