Keyboard does not work at all in El Capitan!

Mac Pro 2009

I did a clean install of El Capitan. So far so good. I have Snow Leopard on another Partition.

Because I have a tremor I went to the keyboard preference to change the delay until repeat. My keyboard then no longer worked.

My mouse, which is connected to the keyboard DOES still work.

There is no return to default option

Is this a good question?

The keyboard does work in Snow Leopard


Who's keyboard are you using? Is it Apple or something else.

Undo what you did in keyboard preferences and see if it then works.


Here's how to reset your PRAM:

Shut down your machine. Yes, all the way down, not sleep or logging out.

Press the power button and then press command-option-p-r. ...

Hold those keys down until your Mac reboots again and you here the startup chime.

Let go of the keys and let your Mac reboot normally.

It did not work. I have tried many combinations and no luck.

I took a photo of the keyboard setup in Snow Leopard and made sure it was the same but again, no luck


Did you check the systems firmware? Follow this Apple T/N: About EFI and SMC firmware updates for Intel-based Mac computers


We still need to know what keyboard you are using as there are also keyboard firmware updates.
