Follow these steps to install the Arduino software on your Mac:
1Go to the Arduino downloads page and click the Mac OS X link to download a .zip file containing a copy of the Arduino application for Mac OS X.
Currently, the file is 71.1MB. That’s quite a large file, so it may take a while to download. After you’ve finished downloading, double-click the file to the Arduino application and place it in your Applications folder.
2Plug the square end of the USB cable into the Arduino and the flat end into an available port on your Mac to connect the Arduino to your computer.
As soon as the board is connected, a dialog box appears, showing the message A new network interface has been detected.
3Click Network Preferences, and in the window that appears, click Apply.
