Just a recommendation from someone who has experience with USB C on Mac’s, where there is an option to buy Thunderbolt 3 versions of the device (hub or cables as an example), pay the little extra and go that route. Both are the same plug but the Mac supports Thunderbolt 3 which requires certification to be branded as Thunderbolt. My experience is that Thunderbolt certified devices are far more stable, and they benefit from even greater capability and performance. As an example, when. I was connecting USB C external storage they would randomly disconnect (especially when tasked), but the Thunderbolt based devices would not. The Thunderbolt devices also would not heat up nearly as much and were faster.
Enjoy the new M1. I didn’t think I would be interested in it, but everything I have read and seen now has me waiting to see what the bigger Pro’s will look like.
