romain5415 Posted May 26, 2015 Share Posted May 26, 2015 Hello, I am looking for help concerning a problem with my graphic cards. Once again, my graphic card is a SAPPHIRE HD 7850 2GB. The problem is that my graphic card seems not to be properly working. This is a fresh install and I only installed these two kexts: AMD7000Controller.kext AMDRadeonX4000.kext Here are some screenshots illustrating the problem: I attached some files in order for you to understand my problem. Thanks DSDT.aml.zip DSDT.aml.zip iMac.spx.zip Unknown.ioreg.zip org.chameleon.Boot.plist.zip Link to comment Share on other sites More sharing options...

You have just correct deviceID for system to understand it. Your 0x6819 is not known for OSX. But 0x6818 yes. There is the method to correct system kexts but they are signed. The is the method to use Clover but you prefer Chameleon. Link to comment Share on other sites More sharing options...

PS: I changed the device ID but it still not working. I guess my system isn't up to date because the version of AMDSupport is 1.1.4 while the one required by AMD7000Controller is 1.2.0. So I'm looking for an older AMD7000Controller. Link to comment Share on other sites More sharing options...
romain5415 Posted June 6, 2015 Author Share Posted June 6, 2015 Hello, So here I am, I did a clean installation of mavericks (10.9.0), made some changes in the DSDT etc.. But now, when the boot up process seems to be completed the monitor turns off. I have the feeling that every time my graphics card is working the monitor isn't. I tried with: - PCIRootUID=0 & PCIRootUID=1 - npci=0x2000 & npci=0x3000 - "Graphics Mode"=1920x1080x32 ... Any suggestions ? DSDT.zip Link to comment Share on other sites More sharing options...

If you are at the deadend then I already have a common suggestion: use Clover. Link to comment Share on other sites More sharing options...
