AutoTDM – Automatically detect plugging in the thunderbolt cable and starting Target Display Mode

Each morning I’ve been hooking my MacBook Pro up to my iMac and having to start Target Display Mode (TDM). Every time I disconnected and reconnected the Thunderbolt cable I’d have to re-establish the Target Display Mode, along with when my MBP went to sleep. So, today I created a simple script to observe the network interfaces and detect when a Thunderbolt bridge was established and then fire off the CMD+F2 Target Display Mode shortcut on my iMac.

I’ve also got a startup script in the project folder if you want to add it to your startup applications.
