problem with mac

Hello
i bought a ardunio experiment kit to learn but i can not try because i can not upload a sketch
I linked my ardunio via usb to my Mac (intel 10.06.08) and every time i try to upload a sketch the ardunio programm says
avrdude: stk500_recv( ): programmer is not responding

when i plug in the usb the yellow power led is on and the 13 flashes every second while pluging in the tx and rx led are flashing 2 times very short
i installed ardunio programm and it runs and when i have the board pluged in i can choose a board in tools serial port (dev/cu.serialusb-a400g15v)
i dont know is there a program i need too or what can be the problem
thx for help

You shouldn't need a program.
Here the Arduino is on /dev/tty.usbmodemfa131

Are you connected through a hub? If so, try connecting directly.

"serialusb" doesn't sound correct. The Uno emulates a USB Modem, so the serial port should be called "usbmodem".

When you connect the Uno, do you get a pop up asking about configuring a network device? If so click configure and then apply. No need to set anything, but you can't click cancel.

What type of Mac are you using?

On my MacBook Air running lion the proper serial port is /dev/tty.xxxx-SerialPort-1

Do you also have dev/tty.serialusb-a400g15v? If so, try that.

Do you have a pre-UNO Arduino with a FTDI USB-to-Serial chip? If so, be sure to install the FTDI drivers.
