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 where our Technical Advisors are available 24 hours a day, 5 days a week to provide assistance.

(5 stars) Mac OS Catalina - works great

By: mross68
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

(1 star) not working on MacOS

By: Cedric
$300 wasted. No working drivers for MacOS. Catalina has been out long enough. I'm considering reselling this product and looking for another supplier

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 the 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.

(2 stars) No Mac support

By: bluestar
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.

(1 star) Does not work with my Mac with OS 10.15

By: pete95
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.
