I did not miss the "Apple" part. Both CalDigit and Belkin each used to have two different TB3 docks on the Apple store (I see that is no longer true). I believe that Anker used to be sold for a while but is no more. There used to be a TB4 dock, but I don't remember which brand as it was expensive enough that we returned it when it didn't work. I have the adapter you pointed out and it also fails. In addition, I KNOW FOR A FACT that this broke with an OS upgrade because I have a precisely identical laptop that runs an earlier version of macOS and the dock works fine. And if I swap the drives, the failure follows the OS. > Has always worked for me on Intel and Apple chips and have seen it always work for every other mac user. 42 people disagree with you: https://discussions.apple.com/thread/253635722 https://discussions.apple.com/thread/253635722 And more: https://www.reddit.com/r/UsbCHardware/comments/sixq3o/weird_problem_with_caldigit_ts3/ https://www.reddit.com/r/UsbCHardware/comments/sixq3o/weird_...
