Mac OS Utilities
K3UI provides a graphical interface for controlling the Elecraft K3 from your Mac. You can connect with a wired serial port or using the Pigtail wireless serial adapter.
The app has a CW/DATA terminal built-in that uses the radio's built-in CW/DATA decode functionality.
There are user-defined Macro, CW and VFO memories built-in as well.
