Macbook air 2019 BCM4355 touchpad + keyboard + wifi

Issues & Assistance Unsupported hardware | Dual boot
1

installed garuda dragonized kde on my macbook air 2019 successfully - I did a complete install on bare metal using iso, no dual boot.

however wifi, built in touchpad and keyboard don't work once garuda loads. but ethernet via usb, bluetooth keyboard and bluetooth trackpad all work fine and the OS operates fine except for those tiny(huge) details.

details on my system:
Intel i7
Broadcom BCM4355
driver wl

these are the suggestions I've tried according to the many other articles on this for macbooks with BCM4360

for wifi I have tried
broadcom-wl (terminal showing that the wl driver is successfully loaded)

for touchpad & keyboard
xf86-input-synaptics
xf86-input-mtrack

have run necessary reboots and also tried linux-lts kernel. no dice.
all help appreciated

Please separate your issues into separate threads, (one issue per thread).

Have you checked the ArchWiki for entries about your model?

3

yes I have checked Arch Wiki. I used the articles on ArchWiki to prepare my laptop for garuda install and read everything on the macbook air but the resources only seem to go up to the Macbook Air 2013 or Macbook Pro 2015, and seem to all mention different broadcom models.

UPDATE

additionally tried to install BCM4350-firmware from aur to no effect

Don't buy Apple products using the T2 chip if you want to use Linux:

The apple products are made that type that they only can run apple OS

if you want to run buy a laptop with windows not macbook

  • it should has supported hardware or else gauda linux will cause some issues

thanks I installed the linked package and got the keyboard and touchpad working. now just the wifi is giving me issues, should I start a separate topic?

Generally that’s best practice.
