hi guys please please please help. this is really urgent..

The FS Command "exec" that we use in projectors are used to run applications. How can we do that on a mac?

On a pc, we target the "exe" file, ... but on a mac?

The situation that im in now is that my projector is required to start a director projector when a button is clicked. I can do that using the "exec" fs command, on a pc.
But how can i do that on a mac?

I would be really grateful if anyone can help. Or even let me know if this is not possible. thanks all.
