(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.
