Tested on MacBook Pro 16 inch 2019 with the latest CachyOS ISO.

You may remove the iwd step in case CachyOS makes iwd as the default. wpa_supplicant no longer works with broadcom chips as described here: https://lists.infradead.org/pipermail/hostap/2024-August/042893.html

It's not, I think we would need to add a chwd profile for broadcom chips to use iwd instead.

chwd profile I guess applies only after the installation is done, so step 3 remains then I guess.

In case you compile your own wpa_supplicant, then just revert this patch: https://w1.fi/cgit/hostap/commit/?id=41638606054a09867fe3f9a2b5523aa4678cbfa5

Fedora has already done this.

brcmfmac driver is part of the kernel. I don't think we really want to make a profile that doesn't install anything. It's easier to just set iwd as default in NM.

Hi

Another workaround to use wifi with wpa_supplicant is adding brcmfmac.feature_disable=0x82000 to the kernel command line. This way you can still ensure wpa_supplicant is being used.

Btw, I also am inclined to remove the firmware package link and just link the wiki page in this guide. Tbh, the link to the package is more illegal that putting an open source APFS driver to the kernel.

[AdityaGarg8]

I myself avoid adding any illegal links on the wiki page of t2linux.

You also could modify your installer to see if any files by the name of *apple* exist in /lib/firmware/brcm during installation and make sure they make sure they get copied to the final install. This way, the user doesn't have to install the firmware again after installing if they copied the firmware for live install.
