@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?

What is the make/model of your WiFi / Bluetooth module? Is it a USB Bluetooth dongle or a PCIe card with both WiFi and Bluetooth?

@CaseySJ this the wifi/bluetooth I have

After updating to Big Sur I noticed sluggish/jittery performance of my apple magic mouse. I'm on Intel CNVI and never had this issue in Mojave or Catalina. This only happens when I have several floating windows open and hover the cursor over those. I know that CNVi module isn't recommended but I am trying to make the best of it. Any ideas?

• If you turn on DisableIoMapper in Kernel --> Quirks section (this will disable AppleVTD) and reboot, does Bluetooth work?

You have special hero status (for the time being ), which grants you immunity from such 'issues'.

[CaseySJ]
