What works by default#

  • Keyboard backlight
  • Screen brightness
  • Video camera

What works but needs tweaking#

  • Wifi - Follow the same steps as described in my previous post. Just don’t do the brcmfmac.conf file as password does work on Fedora by default.

What doesn’t work#

  • Audio - Follow the steps described here

  • Touchbar - This was the hardest.

I think for this one is important to have MacOS installed, if not the device will claim is in recovery mode and will not work, check it with lsusb -t

Get the modules from here. I did the installation through dkms

Add the following files

/etc/modprobe.d/apple_ib_tb.conf

1

options apple_ib_tb idle_timeout=-1 dim_timeout=-1 fnmode=2

/etc/dracut.conf.d/macbook.conf

1

add_drivers+=" applespi apple_ib_tb intel_lpss_pci spi_pxa2xx_platform "

$ sudo dracut -f

/etc/systemd/system/apple-ibridge.service
