A simple bash script to turn off MacOSX 🖥 Airport when the computer is connected to a network adapter.

This is a personal adaptation of the original gist from albertbori My own modifications make it work with my Chinese USB Ethernet adapter.

This is script will automatically turn your wifi off if you connect your computer to an ethernet connection and turn wifi back on when you unplug your ethernet cable/adapter. If you decide to turn wifi on for whatever reason, it will remember that choice.

Requirements

• Mac OSX 10+
• Administrator privileges

Installation Instructions

1)If you have a macbook with integrated Ethernet card you can jump this:

Before installing the script please edit the toggleAirport.sh script at the third line. Now the variable ethAdaptID is set to grep any possible Ethernet Adapter wich name ends with "Ethernet". Run this command: (Fig.)

networksetup -listnetworkserviceorder

And take note of the name of your ethernet adaptor and replace it in the script. In my case: ethAdaptID=".*Ethernet" becomes ethAdaptID="USB 10/100 LAN"

2)Copy and change permission of the files:

• Copy sudo cp toggleAirport.sh /Library/Scripts/
• Run sudo chmod 755 /Library/Scripts/toggleAirport.sh
• Copy sudo cp com.mine.toggleairport.plist /Library/LaunchAgents/
• Run sudo chmod 600 /Library/LaunchAgents/com.mine.toggleairport.plist.

3. Start the watcher.

• Run sudo launchctl load /Library/LaunchAgents/com.mine.toggleairport.plist to start the watcher

Uninstall Instructions

• Run sudo launchctl unload /Library/LaunchAgents/com.mine.toggleairport.plist to stop the watcher
• Delete /Library/Scripts/toggleAirport.sh
• Delete /Library/LaunchAgents/com.mine.toggleairport.plist
• Delete /private/var/tmp/prev_eth_on
• Delete /private/var/tmp/prev_air_on
