Did you used have a Hyper Key set up using Karabiner and Seil, but upgrading to MacOS 10.12 Sierra ended that dream and now you're kicking yourself? I did, and it drove me crazy for two days.

As of the time of this post, Karabiner-Elements is in beta and you need to manually update/create a ~/.karabiner.d/configuration/karabiner.json file (UPDATE: I'm told it's now ~/.config/karabiner/karabiner.json) with the following JSON: { "profiles": [ { "name": "Default profile", "selected": true, "simple_modifications": { "caps_lock": "f18" } } ] } This sets your Caps Lock to the F18 key. * Be sure to launch or restart Karabiner-Elements after you save your changes to the karabiner.json file.
