Wandering in the jungle of internet looking for prolific serial to usb cable driver for mac os x mountain lion. But still can’t make it work well. I’ve already try the official driver, but it’s not working properly on mountain lion. It only appear as dot in my entire screen when I connect it to a cisco switch using mini com.

After wandering again, I finally found the solution. For another prolific users and using mac osx mountain lion, you can try this solution. It works for me.

And finally I can configure any device using serial communication on my mac *insert success kid meme here*
