3DconnexionHelper
3DconnexionHelper is a macOS driver helper component that enables 3Dconnexion input devices to work with supported apps and system features.
What is 3DconnexionHelper?
3DconnexionHelper is a native macOS helper app installed with 3DxWare 10 for 3Dconnexion devices such as SpaceMouse and CadMouse products. It supports the background driver functions that let these devices communicate with macOS and with compatible design, modeling, and navigation software. Users typically encounter it after installing 3Dconnexion drivers, when enabling required driver extensions, or while adjusting device behavior through 3Dconnexion tools. Its role is to keep the hardware integration working reliably so supported apps can receive navigation and input events. On Mac systems used for CAD, 3D modeling, visualization, and other precision workflows, it is part of the normal software stack for 3Dconnexion hardware.
Key features
- Enable 3Dconnexion devices to communicate with compatible Mac apps
- Support SpaceMouse navigation and input in supported 3D workflows
- Work with required macOS driver extension components
- Run in the background as part of the installed 3DxWare driver package

Safety overview
Status: Mostly safe
This item is a legitimate helper component for 3Dconnexion device drivers on macOS. Running in the background and requesting driver-related permissions is normal for hardware support software. If you use a SpaceMouse, CadMouse, or other 3Dconnexion device, disabling or removing it can stop navigation, button actions, or device integration from working in supported apps. Only remove it if you no longer use 3Dconnexion hardware or have already removed the related driver package.
Recommendation: Keep 3DconnexionHelper if you use any 3Dconnexion input device on your Mac. If you have stopped using that hardware, remove it together with the broader 3DxWare software so you do not leave behind an inactive driver component.
