It would be nice if it were possible to connect to a laptop over USB-C for video and power over a single cable and then ALSO run a separate "regular USB 3.0 cable" from the display to your system to create a USB 3.0 data path, but again, it seems that at the moment, when using the USB-C input, you cannot choose a different "upstream" USB port to achieve that. While most KVM Switch solutions are designed to be driver-free, and are compatible with all operating systems including Mac OS, some newer KVMs are designed to be compatible and optimize the experience with Mac computers, for example allowing customizable keyboard shortcuts, or Adders' 'MagicEye' technology which offers enhanced support for MacPro Dithered video without degrading of overall. The reason has to do with how USB-C links work and the amount of display bandwidth required to run this display's resolution.
The reason that can be an issue is that you will only get USB 2.0 data speeds through that link, not USB 3.0. The only thing I will add here is that I seem to remember reading that when using the USB-C input for video, the USB data path is locked to the USB-C port. But if you find confirmation that the U3419W works fine over USB-C with Macs, and that's how you intend to connect that system, then I can't imagine why you'd have a problem also connecting a PC and switching back and forth.

It's not entirely clear what the underlying cause of the problems are at this stage, at least as far as I've seen, but the problems exist. That said, there have been quite a few reports of weird interoperability issues between recent Dell displays and various Mac systems, especially when connecting via USB-C - nothing to do with KVM setups specifically, but rather just general functionality even when that's the only system involved. They wouldn't even be aware of each other. Open Synergy and rename your computer (or use the default name).
Double-click the downloaded MSI file in your Downloads folder (or wherever you downloaded it to), and double click to install it. Get the latest version of Synergy from the download page.
There's nothing about that functionality that would mean you couldn't use a Windows PC and a Mac together. Copy your license key from the account page. The KVM functionality just means that the "upstream" USB data path can be toggled when the video input source is toggled, so that if you have a keyboard and mouse plugged into your display then they will be redirected to a different "upstream" port connected to a different system when you switch display inputs.
