Ever since I was unsuccessful in getting Bluetooth to work on my Mac, I can't access the serial port.
"dev/tty.serial-A901QLM4" shows at the bottom of the sketch, however Tools/Serial Port shows only "dev/tty.Bluetooth-Incoming-Port" with no other port options. How do I get Arduino to access the USB serial port?
Thanks,
Ed

Connect the USB cable to the Arduino and the Mac.  Select the serial port from Tools->Port.

If the serial port does not appear there is something wrong with the Arduino, USB cable, USB port, or driver. 

If you run System Information does the USB device show up under Hardware->USB?
