This page is a step by step guide to get wifi working on supported models.

Note that currently not all models have support, see Is my model supported?.

Is my model supported?

You can get your model using system_profiler SPHardwareDataType | grep "Model Identifier" on macOS or using cat /sys/devices/virtual/dmi/id/product_name on Linux

  • Did your device release with macOS Mojave or earlier initially?
    • If yes, is it a 15,4?
      • If yes, there is currently no support
      • If no, there is support
  • If no, is it a 16,1 or 16,2?

On macOS

  1. Run both ioreg -l | grep RequestedFiles (the names of the firmware files required by your model) and system_profiler SPHardwareDataType | grep "Model Identifier" (your model identifier) in a terminal and note down the output, you will need both values in the next steps.

On any OS

  1. Look at the ouput of the first command listed above, it will probably look something like this

    "RequestedFiles" = ({

    Navigate to

    Note: In some cases, like when using the custom kernel for 16,1 models, you might need to use the firmware that came with your macOS installation. You will find it in /usr/share/firmware/wifi

    Note: If you do not have the 4364 chipset, make sure to use your chipset's identifier in the firmware names

    • Look at the path of the file in the command output that ends in .trx. On the website, download that file and rename it to brcmfmac4364-pcie.bin.
    • Do the same for the .clmb file and rename it to brcmfmac4364-pcie.clm_blob.
    • In the end, download the .txt file and rename it to brcmfmac4364-pcie.Apple Inc.-MacBookPro15,1.txt but change the 15,1 in this string to model identifier was the output of the second command described here.

On Linux

  1. Now that you got those 3 files, move them to /lib/firmware/brcm/.
  2. Check that the files are in place with ls -l /lib/firmware/brcm | grep 4364. The output should look something like this

    -rw-r--r--. 1 root root   12860 Mar  1 12:44 brcmfmac4364-pcie.Apple Inc.-MacBookPro15,1.txt
    -rw-r--r--. 1 root root  922647 Mar  1 12:44 brcmfmac4364-pcie.bin
    -rw-r--r--. 1 root root   33226 Mar  1 12:44 brcmfmac4364-pcie.clm_blob
  3. You can now test out if the files work by running sudo modprobe -r brcmfmac && sudo modprobe brcmfmac and looking at the list of wifi access points nearby.

    Note: From this point on the instructions might be different for a distribution that you are trying to install.

    Note: Using iwd is technically not needed for using wifi, however wpa2 is unstable without it. Running the command from step 3 would work for connecting to wpa2 networks as well but it would have to be run every time before connecting to a network.

  4. To get WPA2 to work stably, install the iwd package (for example sudo apt install iwd on Ubuntu).

  5. Edit /etc/NetworkManager/NetworkManager.conf to look like the following:

  6. Set iwd to run on boot with the following commands (assuming that you are using systemd)

    sudo systemctl enable iwd
    sudo systemctl start iwd
    sudo systemctl restart NetworkManager

If you wifi disconnects or has issues otherwise its advises to restart iwd: sudo systemctl restart iwd

Custom Kernel for 16,1 / 16,2

As mentioned in Is my model supported? there is wifi support for the MacBook Pro 16,1 and 16,2. This is achived through a patchset for a custom kernel.

  • If you are on an arch based distribution use the following commands to compile the kernel:

    git clone
    cd mbp-16.1-linux-wifi.git
    makepkg -si
  • For non arch distributions follow the Ubuntu Building Guide. Make sure to use mbp-16.1-linux-wifi instead of linux-mbp-arch as the patchset in step 3 however.

Once you have verified that you booted into the correct kernel, follow the Wifi Guide but use the firmware files from macOS (as stated in a Note on the page) and not from a fileserver.
