I'll openly admit from the start that my knowledge is limited in many respects, so if I am missing any "necessary" information, you'll have to tell me what and how to find it.
My issue is that I cannot for the life of me update my drivers. I have an iMac which I run both the OSX Moutain Lion (kept up to date at all times) and then I also have a 64-bit version of Windows 8 which I load up via Boot Camp (it's a WinMac.) Almost everything works fine but neither side will apply updated drivers for my card, which if I am not mistaken is an AMD HD 6750.
The FAQ said that OSX updates them automatically when you do a software update and so I ran a software update and updated drivers were not included in the mix. I've also tried downloading the appropriate files from the AMD website while on my Windows side and each time I run the catalyst installer program it will fail to download, and any attempt to "update driver" from the control panel ends with a message about how my card is up to date, though the numbers are smaller than the most recent shown on the website (again, I don't remember these numbers, I just know that mine is smaller than the ones on the site.)
I apologize for my lack of technical intelligence, it's never been my strong suit by any means.
