TECH_ATTACK Posted November 11, 2017 Share Posted November 11, 2017 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.

Slice Posted November 13, 2017 Share Posted November 13, 2017 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 <key>NVCAP</key> <string>0501000000000100060000000000000f00000000</string> 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. LoadVBios=YES May be you need to inject EDID. In some cases it needed.

TECH_ATTACK Posted November 14, 2017 Author Share Posted November 14, 2017 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?
