Setting up Linux

6. 6. Setting up Firmware

   Setup Apple T2 Wifi Firmware
   Execute one by one:

   sudo umount /dev
   vme0n1p1

   sudo mkdir /tmp/apple-wifi-efi

   sudo mount /dev
   vme0n1p1 /tmp/apple-wifi-efi

   bash /tmp/apple-wifi-efi/firmware.sh

7. 7. Testing Firmware

   Try to Test if Firmware Loaded
   To Check the Logs:

   sudo journalctl -k --grep=brcmfmac

   The output should show a similar Output:
