So those of you with a Mac OS X who also use the handoff feature will have possibly experienced a bug<\/a> with trying to answer calls on the Mac when you have multiple interfaces configured.<\/p>\n

I connect to my home network using the MacBooks onboard airport card and also use a thunderbolt ethernet adapter when sat at my desk. The problem lies when I get back to my desk I have to manually disable the airport card and when leaving my desk I have to manually reenable it again… this drives me insane. Something this simple should be easy to configure on OS X, well it turns out it is!<\/p>\n

Using AppleScript it’s possible to detect the state of an ethernet adapter using a few shall scripts. As such you can then detect the state and use this to toggle the WiFi on\/off using networksetup command<\/a>.<\/p>\n

Here’s the code that’s required:<\/p>\n

But to make your life easier I’ve created an app for you here:

When you’ve got the app running you can tell it to “Open at Login” using the dock option.
