radsherwin Posted July 30, 2015 Share Posted July 30, 2015 These are my specs: CPU: Intel i5 4590 3.3ghzMOBO:Gigabyte GA-Z97x-SLIGPU: AMD Radeon 7770 HD Diamond I'm getting a black screen when I try to boot into my Mac. The Apple logo boot ¼ of the way then it goes to a black screen then it freezes.I have VT-d off and Integrated Graphics off as well. I have FakeSMC(or whatever it was called) injected already. What am I doing wrong? I have also added to 2 kexts AMD7000Controller and AMDRadeonX4000, but that didn't work either. What should I do? Link to comment Share on other sites More sharing options...

vusun123 Posted July 31, 2015 Share Posted July 31, 2015 AMD HD7770 works OOB, you will need Verde.kext to fix the white screen glitches. Also you should play with LoadVBios and PatchVBios. IIRC one of those needs to be checked 1 Link to comment Share on other sites More sharing options...
