I'm using a 16-inch Macbook Pro with macOS Big Sur. I keep this adapter connected to an external monitor and it is very fast! It didn't work until I downloaded the beta driver from the Startech website. I would have easily given this 5 stars if it had been plug and play. But I deducted a star because I had to download the driver, reboot, and then give it access to the system to boot properly. A little fiddly to set up, but took about 10 minutes.
