After purchasing new equipment which is MacBook Pro 13
- Catalina 10.15.7
- 4 x USB-C
- release year: 2020
- model 16,2
I decided to install Ubuntu 20 as dual boot.
Previously I installed Ubuntu from raw .iso but it has created too many problems with drivers:
- keyboard
- touchpad
- WIFI !
Then I came across to ready .ISO Image dedicated for MacBooks generally - https://github.com/marcosfad/mbp-ubuntu
While I was reading the article, I found mention about not working WiFi with MBP 16,1 (I was hoping on 16,2 is working)... after Ubuntu installed I noticed WiFi problem (no adapters detected) - this is where hell began...
I tried several ways to solve this problem (mainly mentioned below) - unsuccessfully.
ioreg -l | grep C-4364 | tr "|" "\n"

- https://github.com/mikeeq/mbp-fedora-kernel/issues/3
- https://vinodhsblog.co.za/ubuntu-20-04-lts-on-a-macbook-pro/
- Using this repo from article above to move drivers from MacOs to Ubuntu side https://github.com/stefanpartheym/mbp15-wifi-driver
- https://github.com/Dunedan/mbp-2016-linux/issues/112
After moving drivers from MacOS to Ubuntu and configured followed by articles and people advices WiFi not working whole time... The last important log about wifi drivers from dmesg:
brcmf_pcie_download_fw_nvram: FW failed to initialize
Can you help me with this issue?
