I also patched my DSDT and added Dual-Link code to GFX0 But when I boot up with GraphicsEnabler=Yes -v the system, despite fully booting up, doesn't switch to desktop but stays at console output. I also dont see any monitors / connectors in System Profiler Link to comment Share on other sites More sharing options...

mendietinha Posted December 31, 2012 Share Posted December 31, 2012 doing some progress here! i think cosmetic for now, but ill keep going... all the right kexts load normally. amdacelerator, amd6000controller, amdsuport agpm etc... lets see... edit: inject vram, rom, framebuffer, disable hd4000, make it work together? the agpm recognizes and apears in the -v boot saying about the board, because i change the 6741 of 6630m to 6841 from 7650m. and it loads properly only using smbios mbp 8.2. otherwise says unknown. any help here willl be fantastic. i change dsdt, agpm, boot, aty...

Lordadmiral Drake Posted January 3, 2013 Author Share Posted January 3, 2013 Success! It works! I updated OS X to 10.8.2, applied the exactly same patches to AMDRadeonAccelerator.kext and AMD5000Controller.kext as before, rebooted, and go fully working graphics Link to comment Share on other sites More sharing options...
