Use one keyboard and mouse across Windows and Mac on your LAN; move to a screen edge to switch.

About
A software KVM for Windows and Mac: one keyboard and mouse control several computers on the LAN, switching when the cursor reaches a screen edge, over encrypted connections and with text and PNG clipboard sync. It does not stream the screen. A fork of Mousehop, itself from lan-mouse, it keeps the Rust input backend and background service and replaces the GTK interface with a MyGo native UI.
