unfortunately this disables the media keys completely -- the point of the linked software is it still allows it for media players intended -- such as spotify; and blocks the apple media player from hihacking
Can you remap the entire keyboard so it's actually an ISO layout? I've been using Ukelele for this, but it's not optimal so I'm going to switch. Was considering Karabiner Elements, but i like Lua so maybe Hammerspoon is better?
