I have a 2017 MacBook pro w/ touchbar and the Dell WD 15 dock (work issued it to me). The dock has thunderbolt, HDMI, and VGA on the back. A single USB-C cable comes off of the dock.
The issue I have noticed is that if all three of my monitors are plugged into the dock, the Mac only recognizes them as a single monitor so its just 3 monitors mirroring my MacBook.
Currently, I had to solve this by using a dongle for two of the monitors, leaving only one hooked up to the dock.
This is not that ideal, for cable management and the fact that USB-C is supposed to be able to handle multiple monitors.
Are there any driver updates or hacks I can apply in order to get these monitors to be independent and not show up as a single monitor? Is this an Apple limitation in place or something else?
Edit: Use this link to install the drivers and the DELL Dock will start working Drivers
