Hi. I'm using OSX 10.6. I installed the Arduino IDE and plugged in my Uno. I saw a popup to 'set up a new serial device', but I stupidly clicked 'Cancel'.
"If you're using the Arduino Uno or Arduino Mega 2560, a dialog box will appear telling you that a new network interface has been detected. Click "Network Preferences...", and when it opens, simply click "Apply". The Uno or Mega 2560 will show up as "Not Configured", but it's working properly. Quit System Preferences. " http://arduino.cc/en/Guide/MacOSX#toc4
Now, I can't find out where I need to go in OSX to do whatever needs to be done. The expected /dev/tty.usbmodem device doesn't exist, and I don't know how to add it.
Is there something I can do to start over? I've tried unplugging & replugging the Arduino several times, I've tried rebooting several times. Nothing seems to work. Help?!
