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
