# macOS Airport
## macOS WiFi Wireless Scanner
If you are looking for a basic WiFi scanner for macOS then the command line airport utility may fit your needs.
The utility is located at:
    `/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport`

Typing the above command path can be avoided by creating a symbolic link to the command in `/user/sbin/` by copying and pasting below into a terminal window.

    `sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport /usr/sbin/airport`
This will allow you to simply type `airport` in the terminal window to execute the command.

##Display Current Status of Wireless
`airport -I` Will provide information about the current wireless connection.

    $ airport -I
        agrCtlRSSI: -64
        agrExtRSSI: 0
        agrCtlNoise: -91
        agrExtNoise: 0
        state: running
        op mode: station

##Disassociate From A Wireless Network
`airport -z` Will disassociate (disconnect) from the wireless network without having to disable AirPort using the “Turn AirPort Off” feature via the MAC OS X graphical interface.

##How To Spoof A MAC Address On Mac OS X
1. use `airport -z` to disconnect from the wireless network (required to change the MAC address)
2. next `sudo ifconfig en1 lladdr 00:00:00:00:00:00:01` (will require root password)
