Calle 24 provides toolbar support for SF Symbols. It achieves this by
substituting Emacs image assets with SF Symbols by proxy.

This package is only intended to be used by Emacs (NS variant) running on
macOS.

You should restart Emacs after running the above command to see the tool bar
images replaced with their SF Symbols equivalent.

CONFIGURATION

appearance-specific images.
