I'm trying to build an Arduino on a breadboard, but for some reason the Arduino Programming language could not find my Arduino over USB, but it can find official ones. I'm using a spark fun FTDI chip to program the board so I called Spark Fun, and after a few phone called they said I need to update my drivers. Well i'm using a mac and from what I read online you don't need to download any drivers. I have the latest version of the Arduino IDE so everything should be up to date. Any Ideas?
