Attached Link: daz forum, mentions changegamma didn't work right on mac in poser pro

Mentioned the materialModbutton.py script in earlier post. I looked at that script in text editor: it's short and just defines some script buttons. It actually sets up one of the buttons [Change Texture Gamma] for running changeGamma.py. I don't have changeGamma.py (did a search in finder) which is why I get the Null or empty script alert when I click that button.

Did everyone get changeGamma.py with their install of PP2010 mac?

In the link above, to daz forum, 2nd to last post, marianner says changeGamma didn't work right in Poser Pro on a mac. So I'm wondering if changeGamma wasn't included with PP2010 mac for this reason. Yet apparently some of you have it. So I don't know why I don't.
