NVDAResmanTesla.kext IOGraphicsFamily.kext
IONDRVSupport.kext   or   You can try to use NDRVShim.kext instead of replacing IONDRVSupport and IOGraphicsFamily post#1875, get NDRVShim.kext from post#1865, at /Volumes/macOS Mojave Patcher/macOS Mojave Patcher.app/Contents/Resources/macOS Post Install.app/Contents/Resources/legacynvidia/NDRVShim.kext   And need to edit NVDAResmanTesla.kext/Contents/Info.plist to add the following string.         <key>com.parrotgeek.NDRVShim</key>
