I've bought an Arduino Uno last week. I've connected it to my Macbook but I cant upload my code. When I plug in the Arduino the window with the Network Preferences doesnt show up. I get the error "Problem uploading to the board". I can choose between 4 serial ports. I've tried all of them but no one is working. I've set programmer to "Arduino ISP".
Can somebody help me figure out whats wrong?
