OSX El Capitan and FTDI USB-to-serial adapter

This post is about fixing the USB-to-serial FTDI adapter on OSX 10.11. Since I upgraded to El Capitan 10.11, my USB-to-serial adapter had stopped working.

Before 10.11 (El Capitan), I didn’t have to download the driver to get my FTDI adapter to work. Unfortunately, now, I have to. I really don’t want to mess with the system to get a single USB adapter to work.

Download this driver

Once the driver has been downloaded, install and restart your OSX 10.11 computer. After the restart, verify that you are able to see the adapter by opening your terminal and enter ls /dev/ | grep serial as shown below

nixmbpr:PYTHON Karlo$ ls /dev/ | grep serial
cu.usbserial
cu.usbserial-FTAJPFTI
tty.usbserial
tty.usbserial-FTAJPFTI

If you don’t see an entry that means that your system doesn’t see the adapter.

Hope you find this post helpful.

Cheers!
