tbar Posted September 26, 2009 Share Posted September 26, 2009 Is there anyone using snow leopard that is having any success with the Radeon HD 3870 Video Card? So far I am only able to boot at all if I remove the ATI3800Controller.kext and the ATIRadeonX2000.kext files. Even then I have no resolution switching capabilities in system preferences, display. I have to manually set the desired boot resolution in the Boot.plist file and those choices are limited to Vesa graphics modes. So attempting "Graphics Mode"="1680X1050X32" the res I normally used in Leo 10.5 results in 1400X1050X32 in SL. I have tried all of the EFI strings available for the card. I'm mostly missing the dual monitor support that I have with 10.5.7. I don't really care that the card doesn't support OpenCL at this point. If there's any support in the works i'd appreciate hearing about it as I can't really afford a new HD 4870. I was also thinking about switching to an NVidia card but there are many complaints about their drivers also. Informed suggestions welcome! Thanks.

lennypenn Posted October 14, 2009 Share Posted October 14, 2009 ...and what about this: http://www.kexts.com/view/95-radeon_4850.html Description/instructions:drivers voor Radeon 4850 en andere ATI HD kaarten Ikzelf heb die in gebruik met mijn R4850 eerst "7_radeon_hd_48x0_drivers.pkg" instaleren en daarna "Patched framebuffers for 48x0 and 3870x2.pkg" en daarna "QE_CI_Exotic_cards.pkg". Have you tried it? I have the same card and want to install 10.6. But I didn't yet, I just was collecting information. Now I am very sad to hear of your (and my) problems. Do you have some news?
