# HIDDriverKit

Develop drivers for human-interface devices, such as keyboards, pointing devices, and digitizers like pens and touch pads.

## Overview

Overview The HIDDriverKit framework provides C++ classes for developing drivers for human interface devices. HIDDriverKit uses the core types defined in DriverKit, and adds features specific to human interface device development. Develop your driver with DriverKit and HIDDriverKit, and package it in an app that uses the System Extensions framework to install and upgrade the driver on the user’s Mac. note: HIDDriverKit is available on macOS.
