BoltKVM
Two-Mac display topology

Arrange multiple Mac displays to match your real desk.

BoltKVM keeps this Mac's display group fixed and lets you position the other Mac's group around it. Side by side, stacked, offset, or mixed: only the boundaries you align become places where the pointer can cross.

The topology editor represents the physical desk.

Each rectangle is a real display already owned by macOS. BoltKVM reads those display groups and lets you move the remote Mac's group as a unit. It does not reconfigure resolution, scaling, rotation, or the native arrangement inside either Mac.

Build the boundary that matches your reach.

You can place the second Mac's group to the left, right, above, below, or at an offset from the local group. A boundary becomes active only where the groups touch, so an arbitrary diagram does not create invisible crossing zones.

Cross where the screens meet

Move the pointer through an aligned edge to hand input to the other Mac. Keyboard input follows the active pointer destination. Cross a valid edge back, or use Quick Switch, to return.

Keep native display ownership

This is input topology, not a virtual display wall. Applications, windows, colors, resolution, and video remain on the Mac that owns each display.

What BoltKVM does not rearrange.

  • It does not move application windows between Macs.
  • It does not merge the displays into one macOS desktop.
  • It does not stream, capture, resize, or encode either screen.
  • It does not override macOS display settings.
  • It does not allow a handoff through a boundary outside the current valid layout.

These boundaries are deliberate: the visual desk remains native, while only trusted input control moves between computers.

Multi-display Mac KVM FAQ.

Can each Mac have more than one display?
Yes. BoltKVM can represent one display per Mac or several, keeping each Mac's native display group intact.
Can I place displays in any order?
You can position the other Mac's display group around the fixed local group to match the physical desk. Only aligned boundaries become active crossings.
Does BoltKVM move windows between Macs?
No. It shares input control, not windows, applications, or screen pixels.
What happens after a display changes?
BoltKVM restores a saved layout when possible or places the updated display set on a valid edge without blocking reconnection. Review the arrangement if the physical desk changed.

Make the on-screen map match the desk.
