kami11o Posted November 26, 2017 Share Posted November 26, 2017 Hi, I've got W520 with running High Sierra on it with configuration based on the great guide by @tluck (http://www.insanelymac.com/forum/topic/285678-lenovo-thinkpad-t420-with-uefi-only). I works great with integrated video card, the only thing that I'm unable to get working is Nvidia card (Nvidia Quadro 1000m). By far I tired the following configuration: SMBIOS set to MBP 10.1 / 9.1 / 8.1 Nvidia Web Driver 378.10.10.10.20.107 Nvidia enabled in the Clover Video card set to discrete in BIOS As a result, after boot, I've got flickering screen with disappearing windows and some artifacts, unfortunately not usable at all. Does anyone has managed to get this discrete card working on this notebook? Thanks 1 Link to comment Share on other sites More sharing options...
slig Posted December 1, 2017 Share Posted December 1, 2017 I have a W520 too. Been using it with El Capitan, didn't tried High Sierra yet. Discrete GPU should be enabled via DSDT. Do you patched your DSDT, or using someone else's patched one? Link to comment Share on other sites More sharing options...

N00b_un_2 Posted December 1, 2017 Share Posted December 1, 2017 Same laptop, same thing. I have everything else working perfectly on latest high sierra (10.13.1, just updated to patch the root exploit the other day). I had the Quadro 1000m GPU working with DSDT injection (not clover) before. Web drivers have never worked on this laptop, I just get a black wallpaper with lots of artifacting, no acceleration. I tried rolling back the nVidia drivers to the 10.12.6 drivers. No more artifacting and I was able to open the DVD player app and move pieces in chess, which I believe means that Core Image is working but Quartz Extreme is not. So, I think I'm on to something here. Not sure what else I'd need to swap out for 10.12.6 components, but I assume it's going to be the graphics related frameworks (OpenGL, etc). I'm going to look at the Sierra Patcher tool I used to install Sierra on some unsupported Macs I own and see what components it swaps out and see if I can't get any closer. Having a Core i7 laptop w/ 32 GB of DDR3 running on Intel graphics is kind of lame. Link to comment Share on other sites More sharing options...
N00b_un_2 Posted December 1, 2017 Share Posted December 1, 2017 I tried rolling back /S/L/Frameworks/CoreDisplay.framework to the version from 10.12.6 and it just crashes on boot. without the rollback, I get a black screen after replacing all of the geforce* and NV* kexts in 10.13.1 with 10.12.6 versions... In the process of un borking my laptop from recovery at the moment... back to the drawing board. Link to comment Share on other sites More sharing options...
