Baxwell Posted July 14, 2016 Share Posted July 14, 2016 Hello, 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, Bax PS, here are the specs: Intel i7-2860QM Sandy Bridge AMD Firepro M5950 1GB 8GB DDR3 240GB SSD USB 3.0 Link to comment Share on other sites More sharing options...
Adam55 Posted September 4, 2016 Share Posted September 4, 2016 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 Link to comment Share on other sites More sharing options...
