Installing Drivers: Macintosh
Look for the Drivers folder inside the arduino-0012 folder and double-click the file called FTDIUSBSerialDriver_x_x_x.dmg (x_x_x will be replaced with the version number of the driver, for example FTDIUSBSerialDriver_v2_2_9_Intel.dmg). Double-click the .dmg file to mount it.
Note
Note: If you are using an Intel-based Mac, such as a MacBook, MacBook Pro, MacBook Air, Mac Pro, or Intel-based Mac Mini or iMac, be sure to install the driver with "Intel" in its name, as in FTDIUSBSerialDriver_v2_2_9_Intel.dmg. If you aren't using an Intel-based Mac, install the one without "Intel" in its name.
Next, install the software from the FTDIUSBSerialDriver package by double-clicking on it. Follow the instructions provided by the installer and type the password of an administrative user if asked. At the end of this process, restart your machine to make sure that the drivers are properly loaded. Now plug the board into your computer. The PWR light on the board should come on and the yellow LED labelled "L" should start blinking. If not, see Chapter 7, Troubleshooting.
