[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

This is standard BIOS. We're just enabling VT-d.

I have an Asus X299 Prime Deluxe II with built-in Titan Ridge (origina FW). You helped me get my Apollo connected and Thunderbolt Bus to show, but think I’m out of my depth with modifying a BIOS with those drivers. Or am I?

My X299 is unmodified. Just made the described changes to config.plist and enabled VT-d in BIOS.

Hi @NorthAmTransAm, I too am trying to play along with my Z370 but I can't boot into Mojave with any OpenCore EFI higher than v060. (My #2 build in my signature is this same Gigabyte AOG7, F15a ). Would you mind looking at my attached Z370 EFI and tell me what may be preventing me from loading the OS on any version higher than OC v060? Please and thank you.

Hello @jiffyslot
could you please try attached EFI please and let me know if it worked for you or not

Sure thing. Will look at it tonight!

Sorry, I lost track of the process, but I reread and understand now. Does this only work on flashed Thunderbolt chips?

D'oh! It didn't work/I couldn't load Mojave. I took a photo of the panic screen after the OC boot:

My X299 TB3 is not flashed.

Does your Ethernet 2 work?

Yep both ports work. The ASUS Sage/10G has a Intel X550-AT2 so I modified the EEPROM to work with SmallTree drivers

SMBIOS: MacPro7,1

BIOS changes: None - Can't seem to find VT-D in the ASUS X299 BIOS
config.plist changes: DisableIoMapper (false)

• AppleVTD Enabled
• DMAC
• 4 DIMMS (4 x 16GB @ 3200)
• Broadcom BCM943602CDP (Wifi + Bluetooth work)
• Both onboard Ethernet ports work - Intel X550-AT2 with SmallTree8259x.kext
• No Thunderbolt card (Will be getting a Titan Ridge to flash)

Are you booting from the correct SSD? Please check Boot Priority order in Boot section of BIOS Setup. You can also press F12 at Gigabyte Splash Screen to open the BIOS Boot Menu.

Yes Casey I am booting from correct SSD and already tried that option F12 and all still getting the same thing everytime

@CODYQX4 @yosoyoco @gandem,

What is the speed of your memory? 3200MHz? 3600MHz?

@NCMacGuy --> 3200MHz
@CaseySJ --> 3200MHz
@yosoyoco --> 3200MHz
@gandem --> 3600MHz (Z390 Aorus Master)

3200Mhz

I might give the Fenvi removal a try soon
