In Topic: No graphics / USB / Audio after wake

Honestly, this is a little bit off topic, but it seems like more and more real Mac users are affected by this issue too. Obviously, failure by design is their new strategy. See for yourself: http://www.apple.com...lay?page=0&rf=1

Dp55WB isn't uefi

It doesn't make a difference if it's UEFI or BIOS, at least with regard to the NIC.

At the moment I have not worked on my MB intel DP55WB when i try Mavericks and it generates this error. I need a hand, thank you.

The UEFI network stack or some kind of remote management software is still in control of the NIC preventing the driver from taking control. Check you UEFI settings and disable it.

Since on most laptops the output of the dedicated graphicscard is going into the integrated graphics, which is connected to the display or hdmi and forwards the input, wouldn't this be a problem in macOS, or is it tunneled through the integrated as well on real MBs?

Sorry for OT..

Device GMUX is a microcontroller which controls an analog switch to multiplex the display outputs from the IGPU and the dedicated GPU to the panel. In order to prevent flickering, GMUX synchronizes both display signals by extending the vertical blanking gap. This procedure is patented by Apple (see link in the Linux driver) so that other manufacturers will probably use a different method to switch GPUs.


Provided there is a Linux driver for switching GPUs on your notebook too, you could examine it in order to find out how this task is performed on your machine.

Thanks. I guess it's the same an all Macbooks then.

All MBPro's and the 2013 MacPro have device GMUX, aka GCON on the MacPro, to switch between GPUs. For details how this works, please see the corresponding linux driver where you can find more information: https://git.kernel.o...s/next-20161220


By the way, as GMUX is an I/O-port mapped device, you could make a FakeGMUX kext (just like FakeSMC emulates Apple's SMC) for notebooks with switchable graphics, provided you know how your notebook switches between both GPUs.
