Just starting with Arduino and have gotten stuck at the first hurdle: trying to connect an Arduino Nano with my Mac Book Pro which runs 10.10. I can't seem to find the right port as all suggestions have bluetooth in the name and none with USB anything. Also the post list does not change when I plug/unplug the Arduino. Looking at http://arduino.cc/en/guide/macOSX#toc3 it says that I need to install FTDI software to get the USB port to show, however, having done this it still does not work. Any suggestions?
