Re: Linux Installation - MacBook Air 2020

I tried installing all those things and the b43-fwcutter

I tried to install the modules

modprobe wl

modprobe applespi

modprobe appletouch

None of them are working, some extra lines appear in the dmesg output after modprobe

first you're using a mac with t2chip(as i can see it in lspci).
As far as I know if T2 is not doing something crazy in the background the following standard steps should work.

for the wireless card(broadcom):
install broadcom-sta-dkms , firmware-brcm80211 , linux-firmware , linux-firmware-free,,non-free packages
i don't if your card source is available yet in these packages but if available they should work

for the builtin keyboard,touchpad
As i can see these are not connected to system through usb or i2c and not reported in ACPI tables in standard way(Apple way of doing things nonstandard) as a result they are not detected(assuming i read those files correctly).
So you have to load the " applespi " module manually if it works after loading, then add etc/modprobe/... files.
for the audio
The audio modules are loaded correctly and should work fine.
if they are not then i don't know why.

I downloaded the bullseye alpha 3 installer,

My computer is a Macbook Air 2020

I shrank the Apple partition, disabled secure boot and I was able to
boot with the Debian installer.

The keyboard, mouse, wifi and sound don't work in the installer or in
the installed system. I had to use a USB keyboard and mouse connected
with a USB-C dock.

During install, the grub install failed. I booted with the altlinux.org
resuce image, entered the Debian partition with chroot and used apt to
install the Debian refind boot manager package. refind is working but I
have to press Option every time I turn on the machine, otherwise it
always goes to Mac.

Can anybody tell me how to make the builtin keyboard, trackpad, wifi and
sound work again?
