This is a bash script that 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. This was improvised from this mac hint to work with Yosemite, and without hard-coding the adapter names. It's supposed to support growl, but I didn't check that part. I did, however, add OSX notification center support. Feel free to fork and fix any issues you encounter.
Most the credit for these changes go to Dave Holland.

To debug, just run: sudo /Library/Scripts/toggleAirport.sh
and add echo's wherever you'd like
Keep in mind, that Growl has been deprecated and on a new BigSur installation it won't be there.
So the Airport toggling is no longer being announced.
