Dell 1820a working in Lenovo m700 - OpenCore 0.5.9 - macOSCatalina 10.15.6

Lenovo m700, i3-6100T, 8GB RAM, 256GB SSD 2.5".

This PC uses M.2 slot so most Hackintosh-compatible wifi/bt M.2 cards work. I have a BCM94360NG that works OTB with no extra kexts. But that is an expensive card that I am saving for a mini-ITX build. So I had a Dell 1802a from a previous build, much cheaper ($20) and trying to get it to work.

I get WIFI otb without any extra kexts. The BT is unavailable. Wifi speeds are ac but not as good as BCM64360NG. Here is what I did to get Bluetooth and better Wifi speeds. I can not guarantee this works the same way for your build. This is a Lenovo m700 tiny pc.

Find wifi/bt card device patch in Hackintool -> PCI. For mine it is PciRoot(0x0)/Pci(0x1C,0x0)/Pci(0x0,0x0)

And thanks to Hugotai for this suggestion.

In OpenCore 0.5.9 config.plist -> Add -> PciRoot(0x0)/Pci(0x1C,0x0)/Pci(0x0,0x0) (Dictionary).Add number field under -> pci-aspm-default = 0

<key>PciRoot(0x0)/Pci(0x1C,0x0)/Pci(0x0,0x0)</key><dict><key>pci-aspm-default</key><integer>0</integer></dict>

Then add these kexts to OC -> Kexts

  • AirportBrcmFixup.kext
  • BrcmBluetoothInjector.kext
  • BrcmFirmwareData.kext
  • BrcmPatchRAM3.kext

All are latest versions. I get much better wifi speed now and Bluetooth can connect bt devices.

I have read that both success and failure with Dell 1820a since not all are the same even if the name is the same. On my card it is written "CN-0VW3T3" which I have read is a stable version.Maybe the AirportBrcmFixup.kext is not needed but I left in there. It changes the card to AirPort Extreme in System Information -> Wifi. I have no country_code so it shows as "Country code: US" but has no effect. The speed is great now for the low price of this card. Just do some reading to make sure you get the correct 1820a version.
