Manjaro MacBookPro9,1

Driver Wifi 
 Can you run the following commands one after the other. 
 sudo modprobe -r wl
sudo modprobe b43 allhwsupport=1
 
 That should switch wifi on. To make it permanent open /etc/modules-load.d/modules.conf and add b43 underneath: 
 # List of modules to load at boot
b43
 
 
 Now open /etc/modprobe. d folder 
 Create empty document and name it b43.conf 
 
 Open it and make it look like this: options b43 allhwsupport=1 
 
 Reboot and it should work.
