You can do WiFi monitoring with a vanilla macOS install. And I do mean vanilla.

I drank the linux koolaid and haven't used apple software in ages, but I will consider myself informed, good to know.

last time i checked macbook built in wifi chipset didn't support monitoring mode, need external device.

No external device needed, just root access and I usually make a symlink to somewhere on $PATH:

  $ sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport  ~/bin/airport
  $ sudo airport sniff
  $ tcpdump -r /tmp/airportSniffxxxx.cap | less

You can even use the GUI: http://osxdaily.com/2015/04/23/sniff-packet-capture-packet-t...

There's bunch of cool options, including WiFi quality scan.

It sure does, which is awesome! The UI even has support, and when it’s in monitor mode the WiFi status icon even turns into a solid fan shape with a little eye in it. It’s the little things.

‘jzelinskie has the short instructions in their comment.
