Recently I tried connecting my newly purchased clone version of the Arduino UNO with the MacBook OS X Yosemite. It turns outs that, nothing gonna detect my serial port. This is because most of the clone versions are using a different chip for USB-to-Serial communication namely CH340/CH341 instead of ATmega16U2. After hours of work and digging throughout the Internet, I found these drivers for CH341/CH340 is working as expected. Here how you do it; Download the drivers and install relevant setup. This package includes, drivers for linux, mac os x and windows.
One more additional step for Mac OS X users. Disable the kext signing security setting with this command.
Sudo nvram boot-args='kext-dev-mode=1' How to test it; on the terminal type; ls /dev/tty. you should see something like '/dev/tty.wchusbserial1410'. In addition, if you open up your Ardunio IDE then goto Tools-Port. You should see something similar to below.
