For anyone with this setup hopefully this will help get your build up and running.

First follow this link on tonymacx86 I skipped 15. of Step 2:


Step 3: My BIOS Settings:

BIOS flashed to (2.90)

OC Tweaker Intel SpeedStep Technology (Disabled)

Advanced North Bridge Config - Primary Graphics Adapter (PCI Express)

Storage Config - SATA Mode Selection (AHCI) - ASMedia SATA3 Mode (AHCI)

Step 4: ( I use HDD not SSD ) I skipped 9. And moved to 10.

Step 5: I skipped it all.


At this point I booted into (High Sierra) with no internet ‘ no sound ‘ no GeForce GTX 750 Ti working.



To get (internet) I used KextBeast to add IONetworkingFamily.kext then used a old wifi stick I had Linksys wusb6300

( but try any that you have before going to buy one’ just look for drivers for any that you have already )



I then updated (High Sierra) with ( Security Update 2019-007 ) - this was to get working Nvidia Webdrivers and CUDA


( Webdrivers and CUDA ) ( but GeForce GTX 750 Ti not working yet )


To get (sound) and (GeForce GTX 750 Ti) working I used Clover Configurator :


Sound - add Lilu and AppleALC to 10.13 in Clover Configurator -TOOLS - Kexts Installer


GeForce GTX 750 Ti - Install Webdrive and CUDA - add in Clover Configurator - SECTIONS - Boot - Arguments (nvda_drv=1)
in Clover Configurator - SECTIONS - System Parameters - check (NvidiaWeb)


When all working from USB boot - install Clover to HDD - replace EFI folder from USB to HDD


I used this to get HDD booting without USB (shoutout ‘ctyler’ for linking)
