George I have been an avid user/customer of Portraiture/Noiseware and Realgrain. I have reently witched over to Mac from PC and also upgraded my editing software to Mac Photoshop CS6. Now I have since downloaded Portraiture and Noiseware with no problem to CS6, but where I am having the problem is with a vital part of my workflow...Realgrain. I have downloaded it numerous times but and it show the download to be successful, but when I got to my filters menu in CS6, only Portraiture and Noiseware is displayed. Please advise if Realgrain is even compatible with CS6. Thank you in advance for your quick response.
