(I don\'t want to hear about how crazy I am to want that! :)
Focus-follows-mouse is also known as point-to-focus, pointer focus, and (in some implementations) sloppy
Focus follows mouse is now possible in macOS, Mojave in my case, using chunkwm. See this Stack Overflow response for a "no autoraise" solution. Autoraise is activated by leaving
chunkc set ffm_disable_autoraise 0
in ~/.chunkwmrc
.
Edit 2019-09-12:
chunkwm has been superseded by yabai. To install:
brew tap koekeishiya/formulae
brew install yabai
mkdir -p ~/.config/yabai/
printf 'yabai -m config focus_follows_mouse autoraise' >> ~/.config/yabai/yabairc
brew services start yabai
