VNC client like x2vnc x2vnc is a program that lets you use two screens on two different computers as if they were connected to the same computer.

The overall result is that it works like a dual-display workstation, where the mouse pointer can pass from one screen to the other by trespassing a screen's edge.

But x2vnc is only for a X11 server. EDIT: But x2vnc is not compatible with macOS' screen sharing VNC server.

Is there any VNC client like this for macOS?

Or what's the closest I can get with existing VNC clients?
xQuartz is an open-source X windowing system for macOS. I managed to run x2vnc on my mac:


Install xQuartz.
Download x2vnc.
Within the x2vnc directory, run ./configure
Edit the Makefile to include X11 (sorry I don't know the more elegant way to do this)


On line 7, add -I/opt/X11/include making the full line INCLUDES = -I/opt/X11/include -I. -DVERSION=\"$(VERSION)\"
On line 16, add -L/opt/X11/lib making the full line LDLIBS=-L/opt/X11/lib -lX11 -lm


make and sudo make install
