Arch Linux ISO for Macs with T2

Follow this to build your own iso:

git clone https://github.com/t2linux/archiso-t2
cd archiso-t2/
./prepare.sh
./build.sh

#after you did everything
./cleanup.sh

After everything has finished, you can grab your iso in './out'.

linux-t2 kernel is from https://github.com/NoaHimesaka1873/linux-t2-arch (it will be automatically downloaded when building)

Wi-Fi and Bluetooth firmware

The live system ships apple-bcm-firmware-fetcher, which extracts the Wi-Fi and Bluetooth firmware from the macOS volume on the internal SSD (via the APFS driver in linux-t2). It runs automatically on the first login of the live system, so Wi-Fi is usable right away as long as macOS is still installed.

If it failed (for example because macOS was wiped), run it again as root:

apple-bcm-firmware-fetcher

For other ways to obtain the firmware, see the t2linux wiki.
