Mac OS support by default to map the Caps Lock key as an Escape key.

Back in the "old" days, nobody would have voluntarily admitted they used the regular Escape key implying their hand movement is anything less than optimal. Hell, Mac OS was praised for almost not making any use of the carpal tunnel inducing function keys.

Then the touch bar was released ;-)

For anyone else reading this, the option is found in System Preferences > Keyboard > Modifier Keys...

For more complex modifications there is Karabiner-Elements, which is especially useful if you use Hammerspoon.
