avrdude: ser_open(): can't open device: Resource busy

Reopening my MetroX after nine months, and it already has the Blink program on it. I figured I'd try reuploading the program because it wasn't working. Then I got this error:

avrdude: ser_open(): can't open device "/dev/cu.usbserial-01996BFC": Resource busy

I'm on a Mac and have an Experiments Guide to Metro (METROX) Kit, or whatever it's called.

Is the right board and port selected? Board should be Tools->Boards->Arduino AVR boards=>Arduino UNO, and port should be picked from the list under Tools->Port,

After pressing "Get Board Info", I was able to select the correct port, and the program uploaded successfully. Thanks!
