Asus z370-a / 8700k / ThunderboltEX 3 / iGPU

Finally got everything to work

Asus z370-a intel 8700k ThunderboltEX 3 card Corsair Vengeance LED 2400 8GB Samsung 860 Evo 250GB TL-WDN4800 pcie wifi card


Made a clean Vanilla install (no unibeast / multibeast ) this reddit answer from u/Monewbo guided me through making a clean Vanilla usb boot with a plist very close to what I needed and then this forum thread solved my post install issues.

Kext used: XHCI-200-series-injector.kext FakeSMC.kext Shiki.kext AppleALC.kext Lilu.kext USBInjectAll.kext AppleIntelKBLGraphicsFramebuffer.kext IntelGraphicsFixup.kext IntelMausiEthernet.kext

Drivers64UEFI folder:

OsxAptioFix2Drv-free2000.efi (crucial to make thunderbolt work) AptioInputFix.efi AptioMemoryFix.efi AppleImageCodec-64.efi AppleKeyAggregator-64.efi AppleUITheme-64.efi DataHubDxe-64.efi FirmwareVolume-64.efi FSInject-64.efi SMCHelper-64.efi HFSPlus.efi NTFS.efi apfs.efi


Had to install windows to make thunderbolt work:

  1. install windows 10. don't waste time like me and try shit like WinToUSB or RUFUS, use microsoft's Media creation tool and boot from the UEFI partition of the USB to make the install a breeze)
  2. Once windows and your basic drivers are installed, install thunderbolt drivers from ASUS' website without the ThunderboltEX 3 card slotted in (very important)
  3. download the firmware injector (don't run it yet)
  4. turn off computer
  5. install thunderbolt card in PCIeEX16_2 slot (you can probably use whichever, but you need to select the correct slot in bios setting) Plug in the thunderbolt header from the motherboard. and Asus suggests also plugging a Mini DP to DP cable from the card to your I/O's display port. (I did)
  6. go into bios / advanced and enable thunderbolt (I'll note my settings and update this part shortly)
  7. boot into windows
  8. run the thunderbolt firmware updater. If that step succeed you're on your way if not, verify your bios settings or remove both the card and drivers and start again.
  9. When step 7 is a success, you can turn off the computer, remove the power cable for at least 30 seconds, and then boot into OSX.
  10. Install your thunderbolt device's drivers and reboot if you havent already.

! make sure you have the OsxAptioFix2Drv-free2000.efi in your EFI/CLOVER/drivers64UEFI folder.

by that step, my UAD Apollo Twin duo thunderbolt soundcard was recognized and fully functional. Can't hot swap, but that's not an issue for me.

Let me know if I forgot someting!

cheers!
