# SCSIControllerDriverKit

Develop drivers for SCSI protocol-based devices.

## Overview

The SCSIControllerDriverKit framework supports the development of DriverKit extension (dext) drivers for devices that communicate using SCSI protocols.

Develop your driver by subclassing [`IOUserSCSIParallelInterfaceController`](/documentation/SCSIControllerDriverKit/IOUserSCSIParallelInterfaceController), overriding all methods the framework declares as pure virtual. Then package your driver in an app that uses the <doc://com.apple.documentation/documentation/SystemExtensions> framework to install and upgrade the driver on the user’s Mac.

> Note:
> SCSIControllerDriverKit is available on macOS.
