@CaseySJ and the rest of you guys on this board... you're just the best! Going to OC 0.7.1 and Monterey was just cake

Please note that HackinDROM App isn't fully Monterey compatible yet!

@yosoyoco I am trying to figure out how to modify my DMAR table but its not clear what is needed looking at your modified DMAR. Here is my DMAR, if you can help much appreciated:

Please see this post, but this is not needed on X299 systems unless your WiFi and Ethernet do not connect after enabling AppleVTD.

SetupVirtualMap --> enabled If I understand correctly the OpenCore configuration guide, the default is false. Why is it enabled? Thanks, Juan Initially it didn't work as pointed out in Post 2 of this thread. But it seems to be okay now. If you have trouble with it, please let us know and...

** Enabling AppleVTD on Z390 Designare with No Impact to WiFi/Ethernet **
Credit: @yosoyoco​

Finally we are able to enable AppleVTD without incurring the side effects of broken WiFi and Ethernet. Thanks to @yosoyoco for solving the final piece of the puzzle!

Steps:

• BIOS --> Enable VT-d
• OpenCore --> Uncheck DisableIoMapper from Kernel Quirks
• OpenCore --> Remove dart=0 from boot-args if it exists
• OpenCore --> Add SSDT-DMAR.aml (attached) to ACPI --> Add section as shown
• OpenCore --> Delete DMAR from ACPI --> Delete section as shown
• Reboot

Once this has been more fully tested I'll incorporate it into next month's OpenCore 0.7.2 release.

Warning:

• The attached SSDT is only for Gigabyte Z390 Designare only.

@CaseySJ I followed the instructions and now I've got AppleVTD, WiFi, and Ethernet all working with 128GB of RAM! Mad scientists in this group for sure!

Yes, ethernet is not connecting after enabling AppleVTD which is why I asked for help.

Hello @taylorsyn .

You can try this one

Random observation for those with VT-D enabled and who use VMware:

VMWare either needs to be fully reinstalled or need to double check that security preferences did not get reset for the drivers. Tested on both Big Sur 11.4 and Mojave Had a heck of a time trying to get peripherals to reappear even though system prefs said the driver was unblocked.

@qthegaijin

I have VT-D enabled on Big Sur 11.4 and started up VMware Fusion 12.1.2 without problems. I had virtual machines for Windows 10, Linux Mint, Catalina, and Mojave all suspended. Each reopened without incident and seemed to be running as they usually do.

@yosoyoco Thanks so much, I have it loaded but with VT-D I still do not get any internet, with VT-D disabled and using this patch I do have internet. Perhaps it needs a revision?

Can you export and post your PCIe list from Hackintool ?
