Mojave on the Precision m6700 - Need some help with sleep and Nvidia GPU

Hello everybody, I'm trying to put the finishing touches on my Mojave install and have hit some snags. I'd like to preface this by saying that, while I'm pretty good with computers, I am an absolute noob at hackintoshing.

I got Mojave up and running using clover with everything working but sleep, the dedicated k5000m GPU (shows up in system report and OpenGL Extensions Viewer but nothing seems to be able to use it), and brightness only sorta works. 

 

Sleep is the biggy. When I put the laptop to sleep (via any method eg. Apple > Sleep, power button, or lid close) It seems to go to sleep (power light slowly pulses and everything), but it takes a solid 30-45 seconds to get there. When I try waking it the fans will kick on for about a half second then it drops back to sleep mode. When I try again the fans do the same thing and then a few seconds later the computer reboots with Optimus disabled. It really baffles me as to why Optimus turns off every time I try to wake it. So far I've tried disabled Hibernation by following Hervé's guide here on OSXLatitude and gone through every Darkwake option. Neither changed the sleep behavior in any way.

 

The Quadra k5000m seems to be detected fine in system report and OpenGL Extensions Viewer, but nothing seems to be able to use it. Is this because MacOS can't use the dGPU when the laptop implements Optimus? I've read mixed reports on that. I've tried just turning off Optimus in the Bios, but that causes MacOS to crash at boot. If possible I'd really like to have the Quadra working rather than the iGPU because my main use for MacOS is FCPX. 

 

Brightness works, but there's no on-screen indicator when changing it and if the screen turns off, it comes back on at full brightness. There's also no brightness slider in Settings > Display. 

 

I've attached my EFI folder and a debug report I generated with black.dragon74's script. Any help would be greatly appreciated, thank you in advance!

Sleep is not only affected by hibernation mode, it also heavily relies on fully working CPU power management; you don't have that at the moment.

 

Proceed as follows:

  • generate your CPU-specific power management SSDT with Pike R Alpha's well-known generator script (you can Google for it) and place the resulting ssdt.aml file in Clover's ACPI/patched folder.
  • using Clover Configurator app, drop SSDT CpuPm + SSDT Cpu0Ist tables.
  • using Clover Configurator app, select an appropriate quad-core i7 IvyBridge MacBookPro9,x/10,x SMBIOS instead of that incorrect desktop iMac14,2 you currently use
  • and, of course, remove that NullCPUPowerManagement kext you've added to your Clover kexts folder since that completely kills off CPU power management and will prevent Sleep.

Thanks for the reply. Ok, just did all that. Changed my SMBios to MacBook Pro 10,1 and generated the SSDT file and followed it up with the kext for checking CPU power management, these were the results:

There was a whole bunch of stuff above this, but it didn't seem relevant. The CPU clocks match up with what task manager shows in windows. Unfortunately sleep still doesn't work. It behaves exactly as before.

 

Attached is an updated debug folder and EFI in case it helps.

I actually might be able to help with a better EFI for Mojave that I have created myself. It's made from a few EFI folders but all tweaked into one. I'll post it to see if it'll work for you.

 

@katana9x99PS: I also have watched your YouTube video with your m6700 and the GTX 980m. Credits for you making such an awesome laptop even better!
