can not handle 'AppleHIDKeyboard' driver now

[hanks]

Now the specification of my macbook is below:
OS X Yosemite
version 10.10.2
MacBook Air (13-inch, Early 2014)

Use command kextstat | grep Keyboard to check the driver loaded for the keyboard.
Mine is AppleHIDKeyboard.text, and not the AppleUSBTCKeyboard.kext(using the code).

And use command sudo kextunload /System/Library/Extensions/AppleHIDKeyboard.kext/ can disable internel keyboard, but use command sudo kextload /System/Library/Extensions/AppleHIDKeyboard.kext/can not enable it...the only way is to restart your mac now.

It seems only affect macbook air not macbook pro.

I stuck in the same situation...
By the way, after installing the HHKB official driver HHKBProMac201209.dmg, the process identityservicesd cost the 100% cpu usage. I've uninstalled it and still the same. Have you meet the problem? @hanks

Hi, @hanks, I found I can disable internal keyboard on air using this tool https://pqrs.org/osx/karabiner/. It's open sourced on Github. Maybe you should check out to see how karabiner do to disable internal keyboard.
