Here ist the dropping rule:

Yes, same issue for me.

Different board, different BIOS, different DMAR table.

 

[HenryM]

No, I also have the Z490 Vision D here. From experience, the OemTableID is only cosmetic. You can also leave it blank.

 

[CaseySJ]

Yes, OemTableID in this case should be left blank to make the SSDT compatible with a wider set of motherboards.

Damn! I tried almost everything I can think of. With your DMAR.aml it restarts almost instantly after booting. Cannot figure it out.

Dumped my ACPI files and generated new DMAR.aml just incase. Still no joy, just cannot get native wifi on with Apple VTD enabled, Bluetooth and Ethernet are working fine.

This won’t work for everyone. Let’s wait until Apple posts the 13.3 source code.

Sounds good! Thanks for all the help as always!

I'm not sure if this is related or not, but lately every time I cold boot into macOS, I'll get a crash just as it's about to finish booting, and then an automatic reboot. I can't tell when it started, but maybe when I updated to OC 0.9.0 within the past two or three weeks. Just updated to Ventura 13.3 yesterday without issue, but I don't think that's related.

Some suggestions:

• Always good to try these general purpose remedies (these are like aspirin or tylenol):
  • Reset NVRAM
  • CMOS Reset (which requires configuring BIOS parameters again)
• OpenCore most likely has nothing to do with this, but we can always go back to previous version of OpenCore
  • If HackinDROM App was used, it will have created a ZIP backup of previous version

Regarding macOS 13.3:

• Are you encountering WiFi and/or Ethernet connection problems?
• How much memory does your system have?

** macOS 13.3 WiFi / Ethernet Patch Discovered **
Alas it was not necessary to wait for 13.3 source code
Also posted to GitHub​

Problem:
On some systems such as Z390 Designare and Z490 Vision D, WiFi and Ethernet stopped working with macOS Ventura 13.3. This problem affects all motherboards whose native DMA remap table (DMAR) contains one or more Reserved Memory Regions. Further, this problem occurs only when AppleVTD is enabled and more than 16GB memory is installed.

Solution:

• You may re-enable AppleVTD if you disabled it
• Apply the following patch to config.plist -> Kernel -> patch

Patch Details:

• Identifier: com.apple.iokit.IOPCIFamily
• Base: __ZN11IOPCIBridge20addBridgeMemoryRangeEyyb
• Comment: CaseySJ - Fix AppleVTD issue in 13.3+
• Find: 4C89F6E8 9AFF0000
• Replace: 4C89F690 90909090
• MinKernel: 22.4.0
• Count: 1
• Enabled: True

After applying this patch everything is back to normal:
