Currently on the original 8.73. i've been to the ati website, downloaded the catalyst control center and drivers. I go through the process, and when it comes to the install screen, i click install, nothing happens. i get prompted saying it couldn't be installed b/c of compatibility issues. I came across the this article: http://forums.macrumors.com/showthread.php?t=1171062&highlight=drivers+ati+radeon+5750 I've been trolling the forums looking for other articles but its mostly information from 11.6 and up. I dont know what to do with this really outdated driver. Thanks in advance everyone for your help.
