Karabiner-Elements is very unfinished/unpolished though. Like, way pre-Alpha.

It's great that Karabiner is being developed, but given the number of people that are surely using MS keyboards, the situation is rather untenable. The built in key re-mapping using system preferences, at least for my mechanical keyboard, simply doesn't work. This meant that when I upgraded to Sierra, I was left with no way to remap my keyboard.

Perhaps the moral of the story is that if you use an external keyboard, consider waiting on the upgrade to Sierra.

That's exactly what I use it for and just set it up yesterday. The instructions on the home page are fairly abysmal though.

Ditto to the readme on GH. The key (ahem) bits:

1. Create ~/.karabiner.d/configuration/karabiner.json 2. Put some stuff in it (my simple example below) 3. Install the app from the GH page.

Key definitions are in the source code, but if you check the Issues discussion on the Elements project, you'll probably find good examples to send you on your way.

Sample karabiner.json: { "profiles": [ { "name": "Default profile", "selected": true, "simple_modifications": { "right_option": "delete_forward" } } ] }

Try these instead :) http://www.jeffgeerling.com/blog/2016/remapping-caps-lock-ke...

The next Sierra release might allow the Esc key to be remapped natively, through the Keyboard System Preferences...

I do a similar thing: Caps Lock mapped to Control on hold and also Escape on tap.

How did you manage to do that with Karabiner Elements?

Yeah, that's why I've provided the link :) Alternatives!
