The Guix installer does not recognize the Broadcom BCM43602 card used in the MacBook Pro 12,1 as compatible with free software (issuing a warning), despite this card being compatible with the free brcmfmac driver[1].
Even with the driver loaded, the installer still claims it won’t work, and at the network selection part, the installer claims an error has occurred whenever a network requires login.
Does anyone have experience with this card? Or perhaps this is a bug in the installer?

<https://wiki.debian.org/brcmfmac> says BCM43602 requires non-free
firmware.

> BCM43602 requires non-free firmware. —Florian
Thank you for your clarification. I’ve been using an installation image with a firmware package installed that should provide that. To be sure that this is a downstream issue, could anyone verify that the installer is normally able to connect to WiFi networks that require login?
Also, would a properly functioning WiFi card be listed as an “ethernet” connection? I ask, because the installer allows me to scan for and detect networks, but entering ‘ip address’ in a TTY only shows a loopback and and ethernet device.
My apologies if it’s not appropriate to ask for support for this issue here.

I have done some further research on this issue and have determined that
it is both an upstream and non-free issue, so it doesn’t belong here.
For posterity, however, I have found that:
- The WiFi card _is_ the “ethernet” device seen in ‘ip address’.
- The brcmfmac driver searches for the following missing files in the
firmware directory:
1. brcmfmac43602-pcie.txt
This file can be found in the attachments of this thread [1],
where others encountering this issue made it via
reverse-engineering.
2, brcmfmac43602-pcie.Apple Inc-<product name>.txt
3. brcmfmac43602-pcie.Apple Inc-<product name>.bin
Where <product name> is in my case ‘MacBookPro-12,1’.
These files are indicated to be searched for and missing by dmesg
[2], but I have no idea where these would be found. I’d guess that
some more “user-friendly” distros would ship them, so I’ll start
the search with their install images. Again, if the .txt file’s
licensing is OK, it should be in the libre kernel, I think?
I’m going to try to write a package that includes these missing files.
If anyone has any recommendations of relevant mailing lists or resources
for this problem, I would be very appreciative.
