Update your computer to use Thunderbolt 3
Visit http://thunderbolttechnology.net/updates and look for your computer in the list
of aected computers. If your computer is listed, then you must update your computer

instructions on the website or contact your manufacturer.
Verify that your components are Thunderbolt 3 compliant
1. Make sure that you are using Thunderbolt compliant cables. Thunderbolt 3 uses
the same connector type as USB-C. If you are using a USB-C cable that is not
Thunderbolt compliant, replace the cable with one that is compliant.
2. Make sure that the port on your computer is Thunderbolt 3 compliant. Thunderbolt
3 uses the USB-C connector type, but not all USB-C connectors are compatible with
Thunderbolt 3. If you are using a USB-C port that is not Thunderbolt 3 compliant,
switch to a port that is Thunderbolt 3 compliant.
Replace the Thunderbolt cable
• Use the Thunderbolt peripheral with a dierent cable that is Thunderbolt compliant.
Test the Thunderbolt peripheral
1. Use a second Thunderbolt peripheral, and see if it works. Ideally, the second
peripheral is one that you know works in other setups. If the second peripheral
works in the current setup, then there is probably an issue with the rst Thunderbolt
2. Use the Thunderbolt peripheral with a second setup. If it works in the second setup,
then there is probably an issue with the rst setup.
