@CaseySJ,
Just a quick post to confirm that I have successfully enabled AppleVTD on my Z490 Vision G using the SSDT and method you posted a
few pages back ....

Running MacOS 11.4 via OpenCore 0.71, Broadcom WiFI/BT no problems with sleep, everything still working as before ...
From what I understand VT-d only works with type 1 hypervisor's such as Hyper-V, ESXi, KVM and XenServer so no support for Native MacOS VM Managers like VMWare Fusion and/or Parallels Desktop (I use VMWare Fusion) so the advantage of enabling AppleVTD is somewhat mute (please correct me if I'm wrong).
I guess having it enabled and available brings our Hacks a little closer to a real Mac so nice job
Cheers
Jay
