First problem, the online WD19DCS drivers page does not show any macOS support. Second problem, the online U2413 drivers page does not show any macOS support. You should post the setup questions on the Apple Forum to see if they can assist.
Hi, I have two Dell Monitors with DP1.2 and Daisy Chain support (U2413f) and a Dell docking station WD19DCS. I will be getting a Macbook Pro A2141 (16 inch from 2019). How do I have to set up the docking station with the 2 monitors so that I can connect all that peripherie through one Type-C port on the Macbook Pro?
