GTX965m on Notebook (Optimus is disabled)

5 posts in this topic

Recommended Posts

I use a Lenovo P51 as mobile Device with Mac OS X Sierra 13.1. Intel P630 (HD630 Version of the Xeon) is working well. I can disable the iGPU in Bios, so when i boot to OS X the Nvidia Card, that is also installed, is recognized correct. (Vendor 10de etc). But if i install the Webdriver i see that GM100HAL is loaded and registered but Screen stays black (only the text from -v boot is displayed). Is there any way to get an accelerated Desktop? I think i did disable optimus in bios with disabling iGPU, so is there a way to get it full working? (I guess its a EDID or Framebuffer Problem, because Card is recognized full... because GM100HAL is loaded and registered).


Would be nice to get help.

I have notebook Dell Latitude E6400 with IntelHD4000 and HVS5200M. If I disabled Optimus in BIOS then the Intel graphics became off and it boots only with Nvidia graphics. As in your case.

First time I got only black screen  but then I understand that it depends on Board-ID. Even though I set MacBook I have to set Board-ID from iMac14,2 because it uses Nvidia graphics.

Second condition is NVCAP. It is connectors map for driver output.

I set this one


Try the same or look for  other digits.

Third you may need to inject ROM. Get it with Clover F6 function and insert into /EFI/CLOVER/ROM.


May be you need to inject EDID. In some cases it needed.

Ok, thx for the info. So I can hope I can get an accelerated Desktop with Nvidia. 

Is it possible to share your config.plist file? And how can I find other NVCAP?
