Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

Setting SecureBootModel from Disable to Default made the intel WIFI working
But it looks like Thunderbolt is not working? (with either Disable or Default)
(i don't have anything plugged in Thunderbolt for the moment)

Looks like SecureBootModel might be having unforeseen consequences:

• Aquantia 10Gb Ethernet cards seem to work when this is enabled.
• Download and installation of Big Sur public betas work when this is enabled.
• In my case even WiFi, Bluetooth, and Thunderbolt are fully working when this is enabled (Fenvi FV-T919).
• In your case, OpenIntelWireless driver for WiFi (AirportItlwm.kext) does not seem to work when this is enabled.

Regarding Thunderbolt, what symptoms do you see? Please note that System Information --> Thunderbolt must not be used unless your Thunderbolt firmware has been flashed. To check if Thunderbolt is active, look in System Information --> PCI.

My bad! Thunderbolt looks OK then
But yes, for AirportItlwm.kext (and BT handsoff) to work, i need SecureBootModel to Default.

I wonder if this should be reported to the OpenIntelWireless team or the Acidanthera team?

from Earlier Version to New Version **

• Reboot the system and press F12 at BIOS splash screen to open the BIOS boot menu (not OpenCore Picker).
• Select the USB flash disk.

After the reboot>Select USB flash disk... I receive the warning at BIOS splash screen and then I need to do a force restart with power/reset button ( don't know why every image captured with iPhone ends up being sideways, sorry about that):

Maybe we could try the v1.2.0 alpha?

Interesting, I don't seem to have the AppleVideoToolBox codecs in handbrake, just the VideoToolBox codecs (H264,H265) and when I use handbake it's using CPU only; neither the RX5700XT or the iGPU...

I'm starting to think it's just a lack of full support for iMac20,2 SMBIOS. When I rename 'Intel UHD630' in device properties, I lose the iGPU Graph in Intel Power Gadget, but I GAIN the ability to see it in iStat Menus, and on exporting the Sony Camp 4K Demo (as a 4K HEVC file) I get about 75% iGPU load in iStat menus. I'm almost willing to confirm this by trying a 19,1 SMBIOS... but... I'll wait and see.

I don't understand: You already have the latest OpenCore 0.6.2 so what is the reason for following that mini-guide?

Thank you for volunteering!

@CaseySJ the 0.6.2 OpenCore release folder has two folders bother with EFI folders. What is the purpose of both folders?
