I have PScs3 , I don't want cs4 , still learning it . If I install snow leopard , will it affect cs3 . I have been told there are still problems . if that is so , then I shall stay with OSx leopard . What is going on ? Can you help ? Also , Pc's with more in them cost half the price of mac , why . My repair person (mac guy) told me the parts are all made in the same places . Are we paying for just the name and all the mac product line ?
