AD2USB control from MAC

I am using Yosemite on my MAC connected to a AD2USB connected to my Vista 40 panel.
I followed the how-to video for connection:
1) installed FTDI drivers
2) Got the Alarm decoder keypad program, unpacked it and ran it.
I never get communication with the Panel. I change the port in the configuration. It never goes past "Waiting for AlarmDecoder Communications to Open."
The app also quits every time I try to change the address to 10 (the one I chose in my panel).
I have tried a firmware update through the app and nothing happens.
I am a novice at this.
Can anyone help.
