Getting started with Arduino with Yosemite

Normally following the steps from https://www.arduino.cc/en/Guide/MacOSX, Arduino should probably work. However in some cases, likely the due to the chips, the Arduino IDE just couldn't detect the corresponding ports.

Like my another Arduino board, purchased from Taobao few days ago, just didn't show up in the IDE. After googling for some time, the chip is printed with "CH340", so I tried to find the drivers for it. Finally I got the driver here, http://0xcf.com/2015/03/13/chinese-arduinos-with-ch340-ch341-serial-usb-chip-on-os-x-yosemite/

Following the steps as well as the commands in Terminal, it did show up the Port

But code was still unable to upload... :(

Ok, looking back to the steps I did, the symbolic link could be different. The name should be " /dev/cu.wch ch341 USB=>RS232 1420", with spaces in between, so I did another round of googling, and found the solution, to add the quote for the name, and it works :)

"/Users/MY_USERNAME/Downloads/Arduino.app/Contents/Java/hardware/arduino/avr

Inside this directory you can see files platform.txt & programmers.txt.

Inside these files replace -P{serial.port} with "-P{serial.port}".
So you simply have to add the quotes."
