I got the part a few days ago and am still trying out the connections. Mac/monitor with USB-C / USB-C works fine. But it also works with USB-C / HDMI. I want to use 2 Macs at the same time, currently still with 1 x USB-C and 1 x USB-C/HDMI. That's easy too. I even think that I will connect both Macs with one USB-C/HDMI and thus have the USB-C free for the webcam (if it still works with the Macs).
