EdgeFlow is a macOS app that sends the mouse and keyboard of one Mac (the host) to up to two further Macs. The pointer changes machines when it crosses the edge of the screen, or with a keyboard shortcut. The connection runs directly between the Macs — no shared Wi-Fi network, no shared Apple ID, no server in between.
Features
Edge switching — push the mouse across the edge of the screen and the pointer lands on the neighbouring Mac
Keyboard switching — ⌃⌥← / ⌃⌥→ jumps one Mac further without moving the mouse
Machine picker — shake the mouse quickly to open a miniature map of all Macs for direct selection
Shared clipboard — copied text is available on the other Mac (up to 256 KB, never from password fields)
Paired connection — a new Mac can only connect after confirmation on both sides
Emergency exit — control returns to the local mouse and keyboard immediately, at any time
