Hi there,
I just installed manjaro on my mac mini 2018 and I am missing wifi and audio drivers(mac mini has built in speaker).
I tried to update proprietary drivers, but for some reason I am missing that option in my os.
Can some good soul help me solving the problem? 
thanks
provide formated output from:
inxi -Fazy
mhwd -l && mhwd -li
There are NO “propietary driver” or any driver for apple- 
! Apple is designed to be apple and nothing else. if you want to use wifi and audio then buy a wifi and a audio usb-stick and don’t waste time to this crap of electronic.

This does not solve the problem…
you have to search for your self if you want to use such exotic hardware. be aware that apple always does terrible hints to prevent using their hardware with different use. i own a apple myself but it’s a nightmare, never again. below is a link that might help you, wifi might work but audio with mac is adifferent story. very often they use several hardware suppliers and exotic hardware-chips from different suppliers that they mix. it’s a question of gamble to get them run.
for wifi install the broadcom-wl-dkms and the 5.17rt kernel headers
for audio install sof-firmware
then reboot and check
