This disable(/re-enable) macbook's built-in keyboard smarty when your external keyboard connected(/disconnected).

Next, in ./keyboard-disabler.sh, edit VENDER_ID and PRODUCT_ID for your keyboard's one (You can get them by executing $ system_profiler SPUSBDataType):

#!/bin/bash

VENDER_ID=0x04d9 #YOU NEED TO CHANGE HERE

PRODUCT_ID=0x4545 #YOU NEED TO CHANGE HERE

Done. Let's connect your external keyboard!!

Known Issues

When external keyboard disconnect (i.e. re-enable built-in keyboard), be printed all that was typed on the built-in keyboard.

I'm using the trick presented in following thread.

Can I disable internal keyboard/trackpad on MBP? - MacRumors Forums

This problem depends on this trick. But I don't know other way to disable built-in keyboard. We only can be careful.

The integrated keyboard is not re-enabled when no typing with built-in keyboard even once.

To avoid it, please type something before disconnect external keyboard.
