Arduino Nano Atmega328P doesn't work on Macbook I've bought and Arduino Nano compatible on eBay:



But by the time I connect it to my Macbook Pro (OS X El Capitan 10.11.2) doesn't appear under "Tools -> Port" in Arduino IDE:



I've followed some instructions by other posts here in StackOverflow:


Arduino Nano no serial port for MacBook Air 2013
Arduino Nano with Mac OS Yosemite 10.10


But none of them worked :(

If someone could help me out with this issue I'll be grateful.

Thanks.
I was be able to solve the issue.

So I downloaded the signed driver for my chip and now it works :D
