It is not clear to me that SSDT-DMAC is needed because my Z390 Designare with Vt-d enabled has no problems with Ethernet, WiFi, or any other device.
But if someone does have Ethernet and WiFi problems, then I agree they should try SSDT-DMAC.
Because you're experiencing Ethernet and WiFi problems with Vt-d enabled, please try adding SSDT-DMAC from @StefanAM's post directly above. It must be copied to OC/ACPI folder and a reference must be added to config.plist --> ACPI section.
Hello @SardusX,Hi @CaseySJ
I would like to install macOS Big Sur on a second partition (currently dedicated to macOS Mojave) alongside macOS Catalina. My system is obviously based on the Gigabyte z390 Designare motherboard (BIOS v. F9b - with MSR 0xE2 previously unlocked following Your Micro-Guide) with a multiboot configuration on three separate drives (macOS, Windows 10, Linux) using Clover bootoloader in UEFI mode.
I know that I will have to switch from Clover to Opencore (using the EFI folder that You provide in Your Guide) before starting the new installation of macOS Big Sur so I would like to ask you a few questions to avoid adding problems:
- is it mandatory to update BIOS to newer versions (i.e. F9g or F9i)?
That sounds like a good idea actually.- should i reset NVRAM via OpenCore boot window before starting the install from macOS Big-Sur USB pendrive installer?
It is compatible with multi-boot system. But OpenCore may detect Windows differently from Clover. The best thing is for each operating system (macOS / Windows Linux) to be on its own SSD with its own EFI partition. Then OpenCore can easily detect them.- the EFI folder and the config.plist file you provide in your Micro-Guide to Open-Core 0.70 is compatible with a multiboot system as I described above or should I update/fix/change something?
- how can I transfer PlatformInfo information from Clover to OpenCore? Can i use a Plist editor (PlistEdit Pro)?
Use the same SSDT-UIAC... that you are using now. Copy that file into OpenCore's OC/ACPI folder and add a reference to it in config.plist --> ACPI section using OpenCore Configurator:- in the EFI folder that you provide in Your guide there are two SSDTs (SSDT-UIAC-DESIGNARE-Z390-V7.aml, SSDT-UIAC-DESIGNARE-Z390-V7D.aml):are they suitable with my case Fractal Design Define C TG or would a customization be appropriate?
Thanks in advance for Your help
Just added SSDT-DMAC.aml to my Z390 Designare and everything is still working fine:...
- `PNP0200`, if missing, add ***SSDT-DMAC***. Adds Direct Memory Access [(DMA) Controller](https://binaryterms.com/direct-memory-access-dma.html).
Just updated the table. We need to keep looking for differences. There must be something?!?!!@CaseySJ
I have no DMAC device showing in IORegistryExplorer.
After adding @StefanAM's SSDT-DMAC.aml file to OC/ACPI and activating it in config.plist, then rebooting, a DMAC device appeared in IORegistryExplorer. However, board Ethernet and WiFi were still disabled and Apple Ethernet was active.

Please try loading the attached BIOS profile directly into BIOS Setup (Save & Exit --> Load Profile). You may want to save your current settings first. These settings assume AMD GPU is in Slot 1.
Thanks -- this is helpful.
Good idea. The EFI can be downloaded from HackinDROM, which will ensure a high degree of consistency.About the last thing we haven't compared is our config.plist files. Worth a try? I have never used the HackinDROM app for OC updates, instead doing it manually. Perhaps there are some difference(s) there causing the different results.
I'm fairly sure my Big Sur installation was not a clean install, but an update from Mojave. Perhaps I'll try a fresh install of Big Sur on an external drive.
CaseySJ, if you don't need to have a modded Thunderbolt chip, I have the prerequisites and an Apple Thunderbolt Display.** Looking for one LG UltraFine 5K and one Apple Thunderbolt Display Owner **
- To install modified BIOS (via Q-Flash in BIOS Setup) containing Apple Thunderbolt drivers and check:
- Whether Thunderbolt monitor powers on doing BIOS and OpenCore Picker
- Whether Thunderbolt monitor's on-board devices are functional during BIOS and OpenCore Picker
- Whether Thunderbolt monitor is more reliable in any way than before
Ideally you should have 75 or more posts so that Private Messaging is open to you.
- Must own Gigabyte Z390 Designare Hackintosh running Mojave, Catalina, or Big Sur
- Boot loader must be OpenCore
- Must be running BIOS F9i (either the official F9i or one of Elias' modified versions)
- Must own either (a) LG UltraFine 5K or (b) Apple Thunderbolt Display
- LG UltraFine 5K can be either latest model (27MD5KLB-B) or previous version (27MD5KL-B)
