MacBook Pro Wifi on Fedora 24.md

The current kernel/drivers of Fedora 24 do not support the Wifi chip used on my Mac Book Pro. Proprietary Broadcom drivers are packaged and available in the rpmfusion repo.

Verify that your card is a Broadcom using: lspci -vnn -d 14e4:

Sample output:

02:00.0 Network controller [0280]: Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03)

Install

Install the rpmfusion repo, note only "nonfree" is required, as the Broadcom Driver is proprietry: http://rpmfusion.org/

su -c 'dnf install -y http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm'

Then install the akmods and kernel-devel packages (special thanks to @celsom3 for providing this):

sudo dnf install -y akmods "kernel-devel-uname-r == $(uname -r)"

Finally install broadcom-wl package from the rpmfusion repo, which will install kmod-wl, akmod-wl, and other dependencies.

sudo dnf install -y broadcom-wl

Next run akmods to rebuild the kernel extension in the broadcom-wl package:

sudo akmods

Finally, reboot Fedora.

Troubleshooting

• lsmod to list all kernel modules
• sudo modprobe wl will force the wireless kernel extension to load.
• sudo systemctl restart NetworkManager

Mostly worked like a charm on Fedora 30 on late 2008 model Macbook (unibody). I just had to adjust NetworkManager.conf file with then reboot:

Try to put:

[device]
wifi.scan-rand-mac-address=no

in /etc/NetworkManager/NetworkManager.conf

See: https://ask.fedoraproject.org/t/wifi-not-working-on-mac-mini-after-installing-fedora/827/4

I had to omit the second equal sign for the following line on Fedora 32:

sudo dnf install -y akmods "kernel-devel-uname-r == $(uname -r)"

Running it with both equal signs produced the following error:

$ sudo dnf install akmods "kernel-devel-uname-r == $(uname -r)"

Package akmods-0.5.6-25.fc32.noarch is already installed.
No match for argument: kernel-devel-uname-r == 5.6.6-300.fc32.x86_64
Error: Unable to find a match: kernel-devel-uname-r == 5.6.6-300.fc32.x86_64

Thanks a lot! I had almost given up when I found this...

But now I can confirm it works flawlessly in Fedora 33 on my late 2013 15" MBP, with Villarealized's modification.

Trying this on a late 2009 Mac Mini with Fedora Server 36.
After running akmods, I saw the following on dmesg:
[ 1251.670088] wl: loading out-of-tree module taints kernel.
[ 1251.670097] wl: module license 'MIXED/Proprietary' taints kernel.
[ 1251.670099] Disabling lock debugging due to kernel taint
[ 1251.676955] wl: module verification failed: signature and/or required key missing - tainting kernel
That made me a little nervous but there were no more dmesg like that any more after review (not sure what happened).
After finding out how to configure the wireless adapter (BCM4321, btw.) headless via nmcli it's now working fine.

Hahaha - meant to say "after reboot" (not review ...)
