[SOLVED] MacBook Pro mid 2014 no Wifi

I was trying to install Arch on a MacBook Pro mid 2014 onto a USB stick from another USB stick.  The device only has two USB ports so I can't connect another device.
The problem I is that no Wifi device is available.

ip link only shows the loopback device.

The dmesg output regarding the device is:

[      43.793138] b43-phy0: Broadcom 4360 WLAN found (core revision 42)
[      43.793607] b43-phy0 ERROR: FOUND UNSUPPORTED PHY (Analog 12, Type 11 (AC), Revision 1)
[      43.795876] b43 bcma0:1: probe with driver b43 failed with error -95
[      43.797943] Broadcom 43xx driver loaded [ Features PNLS ]

lsmod lists:

wl                    6516736 0
cfg80211              1396736 3 wl,b43,mac80211

How should I proceed? There are several posts explaining that the problem might be the missing firmware but I'm unsure what would be the best approach because I can't connect another device.

Since wl is available, give it a shot.
Add "module_blacklist=b43" to the https://wiki.archlinux.org/title/Kernel_parameters

onto a USB stick from another USB stick

Unsolicited advice: usb keys are not cheap SSDs, if you treat them as such, they will degrade in no time and then die.

Re: [SOLVED] MacBook Pro mid 2014 no Wifi

Thanks for the help. I just want to sum it up what fixed the issue:

In the boot menu press e to modify the arguments and add

 module_blacklist=b43

at the end as suggested by @seth.

The device didn't show up so I proceeded with:

modprobe -r bcma wl
modprobe wl 

And now

 ip link 

shows the device as wlan0 in my case.

Regarding the installation on a USB stick: Yes, absolutely. It's just to take a look at some things and then switch it onto a SSD.

Right, don't forget to install broadcom-wl into your actual system when doing the actual install.
