USB-C hub or adapter not working with your Mac
USB-C hubs need power from your Mac or a separate power adapter to work. If your hub is bus-powered, it can not be getting enough power. Try plugging it into a different USB-C port, making sure it's powered properly, and restarting your Mac — this fixes it for most people.
USB-C hubs are a bridge between your Mac and other devices, but they're picky about power and connection. If a hub isn't working, it's almost always because it's not getting enough power, the port is loose, or your Mac doesn't recognize it yet. Restarting wakes up your Mac to the hub, and a powered hub solves most power problems.
Fix-IT-Bot will walk you through each step — just tap, no typing needed.
Skip — I just want a technicianCommon mistakes to avoid
- Using a bus-powered hub with too many high-power devices plugged in — each device needs power
- Plugging the hub into a low-power USB-A to USB-C adapter instead of directly into your Mac's USB-C port
- Thinking the hub is broken when it just needs to be restarted along with your Mac
Signs you need professional help
- You've tried all steps and your Mac still shows the hub as unknown or won't recognize devices
- Devices work for a minute then disconnect repeatedly even with a powered hub
- Other USB-C devices work fine but this hub doesn't work in any USB-C port
