Hello everyone, I'm using an iMac with 10.6.8 MAC OS (snow leopard) and an Arduino Duemilanove w/ ATmega328. When I try to upload any kind of sketch I get this message "avrdude: stk500_recv(): programmer is not responding" and the uploading stops. I also tried with another computer, this time Win7 , and it worked. I tried with this test here - http://arduino.cc/forum/index.php/topic,73748.0.html - the loop-back test, and it failed. What should I do?

What serial port are you selecting?
Have you installed the latest FTDI drivers from ftdichip.com?
Yes, I have and I know it's strange. I'm using the serial port /dev/tty.usbmodemfd131
Are you sure it is a duemilanove?
FTDI chips are usually named "usbserial" while boards (like the Uno) with the ATmega8u2 get named "usbmodem".
It was a present, and I was told it was a duemilanove. How do I verify that?
Isn't the name printed somewhere on it?
Post (and attach) a clear picture of the board.
Also, just try selecting "Uno" in the Board type to see if it works.
Thank you very much, it is working now. I've chosen "Arduino Uno".
