I want to automatically burn a cross-platform data CD with the same contents each time a blank disc is inserted, and eject it when done. To that end I created a very simple AppleScript that does just that:

do shell script "/bin/bash -c 'hdiutil burn ~/Desktop/catalog.iso'"

It works fine from the AppleScript editor. If I click "Run" with a blank CD inside, it burns the CD with the data from the .iso and ejects it upon completion.

However, if I select "Run ~/Desktop/burn.scpt" as the default action when inserting a blank CD, nothing happens. I actually have to open the AppleScript editor and select "Run". How can I make it actually run the script?

blank cd dialog

Open burn.scpt in the AppleScript Editor and save it as an Application. Then select burn.app as the desired action on CD popup.

  • That's a good idea, but it still doesn't work! If I insert the CD and then double-click the newly created Burn application it works, but it doesn't work if I auto-run it on insert. Commented Jan 21, 2012 at 5:49
  • Hmm. What version of the OS are you running? I'll try to replicate the problem.

  • 'Doh. Sorry, I can't replicate, because my machine running 10.7.2 doesn't have a CD drive. Maybe someone else can help here.

You can use Keyboard Maestro to make a macro to run your shell script.

First make the macro with an 'Execute Shell Script' action like so: enter image description here

Then use start a new 'Script Editor.app' file and paste this:

tell application "Keyboard Maestro Engine"
    do script "Copy Disc"
end tell

^Note the name of the script above (Copy Disc) must correspond to the name of your macro in KM.

Next export with File > Export and use the File Format: Application. I recommend not code signing.

Only thing left is to make sure you set it: enter image description here

There's probably a more direct way to do it, but this works for me.
