- Karabiner-Elements, primarily to map caps lock to ctrl when pressed with other keys and escape when pressed alone, although I also like to bind right command + asdfhjkl to cursor movement keys home pgdown pgup end left down up right respectively.

- yabai/skhd for window management

- brew/mas for package management

- linearmouse to disable cursor acceleration, scroll acceleration, and inverted scroll direction for mice while keeping all those things on for trackpads.

There are other things that I install on my Macs, but these are the programs that I use to fix behavior that I find unacceptable. Additionally I maintain a script of about 50 `defaults write ...` commands so that I don't have to dig around in the settings menus of system applications to configure them to behave sanely (show file extensions and paths, don't reorder Spaces, disable autocorrect, etc).
