If your Aluminum Type-C Pro Hub Adapter is not being detected, the usual cause is a connection that is not fully seated, a laptop case blocking the fit, or a Mac that needs a full restart. The Aluminum Type-C Pro Hub Adapter is plug-and-play with no drivers required, and it uses dual USB-C connectors that must plug into both USB-C ports on your MacBook at the same time and sit flush against the side.

How to fix detection problems with the Aluminum Type-C Pro Hub Adapter

1. Remove any hard shell laptop case before connecting. The Aluminum Type-C Pro Hub Adapter is designed to sit flush against the side of your MacBook, and most cases add enough thickness to prevent a secure connection.
2. Plug both USB-C connectors firmly into both USB-C ports on your MacBook. When the Aluminum Type-C Pro Hub Adapter is properly connected, the small LED on the side lights up.
3. If the LED does not turn on, unplug the Aluminum Type-C Pro Hub Adapter and reseat the connectors firmly.
4. Confirm your computer has two USB-C ports side by side. The Aluminum Type-C Pro Hub Adapter does not support Mac devices without dual USB-C ports.
5. Unplug the Aluminum Type-C Pro Hub Adapter, wait 10 seconds, and reconnect it.
6. Restart your Mac fully rather than just closing and reopening the lid. On Apple Silicon Macs, shut down completely, wait 30 seconds, then press the power button to start up again.
7. Do not install any software or drivers. The Aluminum Type-C Pro Hub Adapter is plug-and-play, so no drivers are required.
8. Connect only one external hard drive at a time. Running more than one external hard drive through the Aluminum Type-C Pro Hub Adapter at once can cause instability.
9. Check which port your accessory is plugged into. The USB-C data port on the Aluminum Type-C Pro Hub Adapter handles data only, so it does not support charging or video output. Use the two USB-A 3.0 ports for flash drives, external hard drives, mice, and keyboards. The Apple SuperDrive is not compatible.
10. For a memory card that does not appear, remove and reinsert the card, then check Finder settings under General and make sure External disks is enabled.
11. Check for a macOS update under System Settings, General, Software Update, then reconnect the Aluminum Type-C Pro Hub Adapter and test again.
