You made three posts in the Mac section within one hour and are disappointed because you got only one answer? You didn't even reply to that answer, did you try to delete the shadercache, like weltall told you?
We have the technical help forum, FAQ-sections for common problems, the bugtracker, ingame help, irc, what else do you want? A 24-hour phone line?
Keep in mind that the game developers are unpaid volunteers, mostly with other full-time jobs. Have some patience and maybe try again on irc at another time of the day. Also, provide as much information as you can. Your problem reports here in the forum don't even contain your hardware specifications and OS version. What error messages did you get? Upload your errorlog.txt and/or the console output somewhere and link it here. Without specific info, we can only guess.
(Pssetup and psupdate don't exist anymore. Start PSlauch and then select "settings".)
