Anyone any closer to figuring out why TB3 hotplug has stopped working on unflashed boards?

Certainly — will post a description shortly.

** Experimental OpenCore.efi with FixAppleVTD Kernel Quirk **
​

Purpose:
The patch to fix WiFi and Ethernet issues in macOS 13.3 has been incorporated directly into a test version of OpenCore. This means it's not necessary to add the patch manually to config.plist.

Instead, a new Kernel Quirk called FixAppleVTD has been introduced that can be enabled and disabled as needed. When enabled, OpenCore itself will inject the patch into the right version of macOS.

To test the new OpenCore.efi with the new kernel quirk, please see this post for details:

** Patch Theory ** Fixing WiFi and Ethernet in macOS 13.3 with AppleVTD Purpose: As requested by some, this post explains how the patch was found and what the patch does. Discovery: Sometimes it is helpful to participate in the Apple public beta program. When the first 13.3 public beta was...

@CaseySJ amazing work as usual !
At this stage maybe it could be useful to post your latest EFI version as you did up to OC 0.74. We are now at OC 090 and so many changes have been incorporated since that time. I use every month HackinDROM to upgrade but suspect that on my EFI some changes have not been included (Ethernet 2.5Gbit/sec for example). That would really be appreciated !
Thanks in advance...

I can post the OC 0.9.1 EFI folder with custom OpenCore.efi to fix the WiFi and Ethernet issue. Will do that in next day or so. Waiting for more test results to come in.

** 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+

• Replace: 4C89F690 90909090
• MinKernel: 22.4.0
• Count: 1
• Enabled: True

Everything working great now in 13.3 on my Z490 Vision G with Fenvi T919 card and 128GB ram

I seem to have stumbled upon an issue with my Z490 Vision D Ethernet i225 on my OC7.7 Catalina system. I just noticed that it is not showing up. I checked the BIOS, and it says i225 is not connected. Any ideas? The two Mac address for both Ethernet ports have their own Mac Addresses, OK. It just seems the MB is not seeing that it is there.

Stumped.....

I have a working Big Sur on OC 0.8.9 (Upto date using HackinDROM) boot and runs fine. It's on a Sabrent drive which I have been reading can turn into a problem so I bought 3 2 TB WD Black SN770 to use.
I followed all the create back up directions ...multiple times (I have the Working drive in the 1st M2 slot and the new Black in slot 2) I can see the new EFI beside the existing EFI and original Big Sur drive, but the new drive does not appear in the OC boot screen. I can see it once I boot back into Mac OS from the original drive and its there on the desktop and it's formatted and files appear the same with one exception there's a folder on the new drive called Previous Content.
Im using the newest version of Carbon Copy Cloner, 6.1.5
Anything need to change with Safety net (turn off?) and uncheck rotect Root-level items on the destination
Any insight would be appreciated.

Does the new drive (SN770) have an EFI partition? And the EFI folder is located in a folder called EFI in the partition called EFI?

Have you tried the two usual remedies?

• Reset NVRAM
• CMOS Reset (which requires re-configuring BIOS parameters)
