Help welcome: Activating the AMD Radeon Pro W6600M GPU

[Gabriel de Andrade]

Hi guys, I hope you’re fine!

 

I embraced the project to Hackintosh the HP ZBook Fury 15.6” G8 Laptop.

 

This laptop features the AMD Radeon Pro W6600M GPU with 8GB of VRAM.

 

This would be an absolute beast with MacOS, except I couldn’t get graphics acceleration with it yet.

 

Boot (ok), MacOS install (ok), everything working like a charm except for GPU acceleration.

 

The AMD Radeon Pro W6600 is natively supported by Apple, this “Mobile” version is supposedly the same, except for lower TDP. That’s why I’m feeling there must be something to make this work.

 

I’m attaching DSDT, Ioreg and SysReport here.

 

Any suggestions? GPU spoofing, flashing the VBIOS, modding the something on Whatevergreen code… All ideas are welcome at this point!

 

Note: This laptop has BIOS deactivation of its iGPU. In the AIDA64 system report you can see no traces of iGPU whatsoever. Everything (screen, HDMI) is processed exclusively through the W6600M so I think an iGPU is probably not the culprit here.

 

Note 2: An attempt to activate this dGPU was made in a recent livestream in a prominent Brazilian Hackintosh channel, https://www.youtube.com/live/PKptbO9Yg1M?si=S49M2dshf1VTHd1h

There is a simple question. You GPU has deviceID=0x73E1 which is unknown for macOS drivers. But 0x73E3 is supported!

You have to make spoofing to 0x73e3. Don't ask me how because I am using Clover and this is usual operation.

@Gabriel de Andrade I don't have experience with your dGPU, but Slice does appear to be correct.  See confirmation here.  Note that you may also need boot-arg agdpmod=pikera.  Your ACPI patch will look something similar to the attached.

I watched the 3 hour live broadcast. The result is no, it is not recognized. Whether you turn off optimus and pretend the internal graphics card does not exist with the mux switch and say that Aida64 does not even see it, Apple has a way of detecting hardware. As explained in Dortania; 90% of discrete GPUs do not work because they are wired in a configuration that macOS does not support.

"0% of discrete GPUs will not work because they are wired in a configuration that macOS doesn't support (switchable graphics). With NVIDIA discrete GPUs, this is usually called Optimus. It is not possible to utilize these discrete GPUs for the internal display, so it is generally advised to disable them and power them off (will be covered later in this guide).

However, in some cases, the discrete GPU powers any external outputs (HDMI, mini DisplayPort, etc.), which may or may not work; in the case that it will work, you will have to keep the card on and running.

However, there are some laptops that rarely do not have switchable graphics, so the discrete card can be used (if supported by macOS), but the wiring and setup usually cause issues."

@strangeron I hope @Gabriel de Andrade is motivated to try by all those who say 'it can't be done.'
