M4600 with AMD GPU - El Capitan


Recommended Posts



I have installed El Capitan on my M4600 (AMD discrete GPU), however I cannot get the onboard graphics to work, only on an external monitor via HDMI. Only one side of USB work, keyboard doesn't work, or touchpad. 


I have seen other threads on the same M4600 but with the NVidia setup. 


Does anyone have a DSDT with the AMD graphics? Or could lead me in the correct direction so that I can finish this headache of a project?


Many thanks in advance,



PS, here are the specs:

  • Intel i7-2860QM Sandy Bridge
  • AMD Firepro M5950 1GB 
  • 8GB DDR3 
  • 240GB SSD
  • USB 3.0

The best way to get AMD FierPro M5950/AMD Radeon HD 6770M to work is to use Clover and in Graphics Injection Select InjectATI, though if you use El Capitan you won't be able to wake from sleep (known issue for every AMD Radeon HD 6xxxx+) and USB 3.0 won't work, Apple made it harder to get non-chipset USB Ports to work on OS X. For DSDT you can go to this thread http://www.insanelymac.com/forum/topic/308718-dsdt-for-dell-precision-m4600/?hl=m4600
