I am on currently on the first nerdkit project, and am using a Mac. Step 10b – Prepare for Programming says "Mac users need to check /dev for a device like /dev/cu.PL2303-0000211A Using the terminal, list the files in the /dev folder, you should see a file like cu.PL2303-0000211A the last 4 numbers will change depending on which port you plug it into. You need to open the Makefile in a text editor and edit the line that begins with AVRDUDEFLAGS. At the end you need to change “/dev/ttyUSB0” to “/dev/cu.PL2303-0000211A” or whatever you saw in the the /dev directory. "

When in terminal and when I type in /dev and then type in ls to list the files in the folder, a file like cu.PL2303-0000211A does not appear. Maybe i am doing it wrong, please help!

You need to have your Nerdkit turned on/in programming mode when checking /dev.

Hi, konradwilkens welcome!

Are you in Terminal??

You have to be using a command line app.

Try again after downloading the latest driver from Prolific's website:

It should be listed as /dev/cu.usbserial

Hi konradwilkens,

It seems that you are not quite in the right place on the command line. My suggestion is to first take a quick go through this library article http://www.nerdkits.com/library/command_line/ it will give you a bit of an intro into how/why we navigate through the command line. It is meant for Windows users, but I think you can get something out of it (on your machine you use ls to list the files in a directory instead of dir).

I think the immediate issue might be that you are not putting a space between your command and your destination

ls /dev

will list is all the files in your /dev directory.
