Here!

When you run IORegistryExplorer, do you see AppleVTD near the top of the device list?

When you say WiFi does not work, does that mean it (a) can show list of SSIDs, but (b) cannot connect to any SSID?

Yes, I can see apple vt-d in the ioreg. It cannot find any network, and therefore connect. If the Wi-Fi logo appears, but after a minute it is crossed out

Hi @CaseySJ ,
With the 13.4 update, i lost my network. WI-FI and ethernet not working any more. AppleVTD and your patch enabled in my config.plist.


Problem solved. Kernel quirks "DisableIoMapperMapping" was unchecked.

Good morning all and @CaseySJ ! Since the beginning I am on F5 BIOS version.
I was wondering if there is any specific advantage in moving to another one; i.e., F20?
Thanks in advance for your advice !

Hi there, @CaseySJ! Since initially talking with you in the early weeks of this build I've enjoyed a practically *flawless* experience. However, I started to get more and more prompts in my software to upgrade from Catalina, so here I am, having upgraded to Opencore 0.92, BIOS F20, and Ventura 13.4.

However, since upgrading, I have experienced a constant stream of crashes. Generally, I can get about fifteen or twenty minutes of use before the computer entirely freezes, and then restarts moments later. Despite my debugging attempts, I have not been able to figure out what is wrong: I am using the computer as normal with no additional peripherals, typically just using Chrome or VSCode, and there is no sluggishness in the system at all preceding the crash.

I hoped I could prevail on you to help me figure it out. Here are some screenshots from my OpenCore config. In my BIOS (F20) I have set it to the settings described in your initial guide, except I have not made any BAR selection. I have attached some of the crash logs from the `WindowServer` in case those are revealing. Thanks again for your help!

Sorry, I had a mini vacation. Everything worked! I tried the recommended EFI, which there, from what I understand, was the DMAR SSDT modifier. But I swear I'll try. I must have done it wrong, but I would like to clear up some doubts. Despite using disableiomappermapping, should I also Delete the ssdt dmar and inject the modified?
