A long time ago, i used to have High Sierra installed with a GTX 460, it was using the VGA signal just fine, the only difference is that it was not with an adapter DVI-VGA, it was a native VGA port. Maybe the VGA signal on the DVI-I port on the GTX 970 is not properly installed in High Sierra.

That will install the latest nvidia driver, but why is there no gpu acceleration and my screen resolution is still 1024x768. Also, in the boot clover options, do i select both nvidia web drivers and inject nvidia ? I´m using DVI-VGA adapter with the GTX 970, could there an issue with this configuration.

What is causing the web driver not to install is the build 17G66, i even tried to apply the update from the Apple Store and the system was not booting anymore, going to try another install. I installed version 17G14033 from update, then i installed the web driver version Nvidia Web Driver - 387.10.10.10.40.139 , after a reset the system cannot boot into desktop.

Its a big of a mess, but I managed to install the internet kext. Now the issue is with Nvidia Web Driver, stuck on 1024x728 resolution. Also I tried to install the newer Nvidia Web Driver for High Sierra and it says that its not compatible. The windows graphics have many glitches, when using Safari or Firefox.

I think it is a Realtek GbE LAN chip (10/100/1000 Mbit) And i also think that RealtekRTL81xx.kext could be the fix, but i dont know how to install it.

PS. I have tried to install the latest version of High Sierra, and no ethernet and the gtx 970 graphics card shows as "monitor 3mb". I have no ethernet, how do i access OpenCore Sanity Checker from an offline High Sierra installation? https://opencore.slowgeek.com/
