Updating the Wi-Fi/Ethernet toggle script for Mavericks & new MBP
Have a look to a different script for the same purpose, but with a slightly different approach. It uses the same SystemConfiguration trigger, thus. The problem on Mavericks seem rather to be respawning the original script over and over by launchd. I'm successfully running it on Mavericks 10.9.3. The Script can be found here: http://www.computernetworkbasics.com/2012/12/automatically-turn-off-wireless-in-osx-including-mountain-lion/
