Mr. Zarniwoop Posted February 6, 2015 Share Posted February 6, 2015 Mr. Zarniwoop, what did you change in the ATIRadeonX2000.kext? Did you do something else to the AMD4800controller.kext? I know you've moved on, but I stumbled across this and thought I'd answer in case it helps others. Yes, I changed both of those kexts by first patching them as netkas' QE/CI 48xx exotic card patch, and then after that doing my HDMI patch. It looks to me like you only did my HDMI patch. You might want to find the QE/CI 48xx exotic kexts as a starting point, and then do my HDMI patch which changes the DP personality to HDMI. 1 Link to comment Share on other sites More sharing options...

Mr. Zarniwoop Posted February 14, 2015 Share Posted February 14, 2015 is there a step i am messing ? i'm using the QE\CI 4800 Exotic patch for 10.10.0 I always needed to install the new Kext with Kextdrop or something similar, otherwise it didn't rebuild the Kext Cache and use the newly patched kext. Otherwise, it sounds like you did what I would have done. HDMI was recognized once the Mac OS X desktop appeared. Link to comment Share on other sites More sharing options...
VirusX Posted February 15, 2015 Share Posted February 15, 2015 Thanks for the follow-up. For everyone who is using clover: There is an easy way to patch the framebuffer with clover now. The procedure is described here. With Clover Configurator it is even easier - give it a try No need for manually patching some kexts, installing them and rebuilding caches etc -- just change the clover config file with clover configurator, save and reboot and test btw: DVI and HDMI incl audio works nicely with my R9 270X Link to comment Share on other sites More sharing options...
