Frequently Asked Questions

Before You Buy

Thunderbolt 3 uses the USB-C connector, but not all host connections, cables, and devices with a USB-C connector support Thunderbolt 3. This means that a USB-C device is compatible with a Thunderbolt 3 host connection, but a Thunderbolt 3 device is not compatible with a USB-C host connection. Therefore, it is essential to know whether you have a USB-C or a Thunderbolt 3 host, cable, or device.  

To determine if your component is a Thunderbolt 3 device, look for the Thunderbolt 3 symbol. USB-C devices do not include this symbol.  For more information about USB-C, see the following FAQ: http://www.startech.com/faq/usb-c-port-capabilites

Does not work with my Mac with OS 10.15

By: pete95 - 10/16/2019
well, I haven't been able to try it. It would not work on my new Mac with 10.15 Catalina. Im not going to downgrade my Mac so I can use this adapter. So they need to address the fact that people update their machines. the product itself looks good and feels like a good quality product and the thunderbolt cable it ships with is really nice. So if it had worked, I would recommend.

We are aware of this issue and apologize for the inconvenience. macOS Catalina (10.15) removed support for 32bit software/drivers, and while updated 64bit software/drivers have been requested from the manufacturer of the chipset used in our TB310G, they have not yet been provided to us. A workaround would be to remain on 10.14 or to reinstall 10.14 (or an earlier version that is supported). Again, we apologize but unfortunately, this product is currently incompatible with macOS 10.15 for the foreseeable future.

No Mac support

By: bluestar - 10/18/2019
I´ve used this adapter om my Mac Mini 2018. Works fine, but I need to upgrade to the latest macOS. The drivers doesn´t support the latest version, and therefore it´s keeping me from being able to upgrade. Startech needs to fix this rigth away.

macOS Catalina (10.15) requires 64bit software/drivers and unfortunately removes support for 32bit software/drivers. We are working to retrieve updated drivers from the manufacturer of the chipset used in TB310G, however until we receive them, this product remains incompatible with 10.15. For it to work with your computer/system, you’ll need to either remain on 10.14 or reinstall 10.14 or an earlier version if you have already updated. We understand this may be frustrating and we apologize for the inconvenience. If you’d like to speak directly with one of our support team members, you can contact us at www.startech.com/support.

By: mross68 - 01/22/2020
I had this installed with Mojave and then upgraded to Catalina and never once has it stopped working. Shows link speed at 10gb and transfers data up to 2gb of speed. Almost 2 years without any issues

By: BG TV - 08/05/2020
Please be warned this will not work with your Mac products. You will not get the desired speeds. Also we have waited over 6 months for a firmware update to fix.
