• There's a new Mac app called Serial, available in the app store. Full disclosure- I wrote it. The main advantage over other apps is it can work with most USB to serial devices without having to install any drivers, as it has its own drivers built-in.

This method works equally well if you want to connect to a serial bluetooth device. You must simply make sure that the bluetooth device is paired and active. Then you will be able to see the device in the list of devices. Once you’ve connected to the serial bluetooth device with screen, the connection will be held active for the length of your session.
I’ve used this method to connect to the sparkfun Bluetooth Mate Gold. It simply appears as a serial stream that you can communicate with exactly as you would with any other serial device.
