I bought an UNO R3 to learn with. I have not been able to make it work with my iMac running 10.5.8. The Arduino is recognized and listed in the USB device tree as "Arduino Uno". When I unplug the cable and refresh the USB tree, it is not listed. When pluged back in, it re-appears normally. The Arduino board seems to work fine (power led is green and yellow L Led is blinking when connected to the power supply via USB)
The board is selected as "Arduino UNO" in the Arduino window (Is this what people refer to as the IDE?)
The serial port is listed as "/dev/tty.usbmodem1d11"
Every time I try to upload a sketch I get the message:
avrdude: stk500_recv(): programmer is not responding
I have tried the various combinations of reset buttons, unplugging, etc that I read about while searching within the forum. Can anybody tell me if Arduino will work with OSX 10.5.8 and how?
Thanks in advance for any help you can provide.
