Thunderbolt device not recognized by your Mac
Your Mac either isn't detecting the Thunderbolt connection or your device needs to be authorized. Unplug your Mac, plug it back in firmly, and check if your Mac asks you to authorize it. If it appears after firmly plugging it in, restart your Mac. This fixes most cases.
When a Thunderbolt device won't show up, it's because the cable is loose, the firmware needs updating, your Mac needs to authorize it, or the Thunderbolt driver needs restarting. We'll check the physical connection, restart your Mac, and check if authorization is needed.
- ✓Check that the Thunderbolt cable is firmly plugged into both your Mac and the external device
- ✓Make sure your external device is powered on and has a full battery if it's wireless
- ✓Know your device password or PIN if authorization is required
- ✓Check that your Mac's Thunderbolt port isn't damaged or blocked

Skip, I just want a technicianCommon mistakes to avoid
- Forcing the cable into the port instead of trying it gently, which can damage the connection
- Not realizing the external device firmware can be too old for your Mac
- Assuming the port is broken when the cable is actually just loose
Signs you need professional help
- The cable is firmly connected, you've restarted your Mac, and the Thunderbolt device still doesn't appear at all.
