> I want to share keyboard, mouse and monitor between a PC and a MacBook. A KVM with DP+USB on one side and Thunderbolt on the other doesn’t seem to exist.

It does if you use the built-in KVM in a recent Dell Ultrasharp display, and change Thunderbolt to USB-C.

My setup is a MacBook Air plugged into the USB-C port, a Windows PC plugged into the Displayport/USB port. Mouse and keyboard are plugged into the display.

I switch inputs via a StreamDeck. The StreamDeck just sends a key command; on macOS, BetterDisplay handles input switching, and on Windows, the Dell Display Manager app does the job.

Switching is a touch slower than I'd like, but beyond that, it's flawless.
