Continuo is not screen sharing. Each Mac keeps its own display. What crosses the network is your keyboard, pointer, and (when enabled) clipboard and files.
One Mac holds control at a time
Exactly one Mac receives injected input at any moment: the one your cursor is on. The Mac you are physically typing on always wins if both try to claim control at once.
If the link drops or something goes wrong, Continuo releases control immediately rather than leaving a remote Mac stuck mid-keystroke.
Crossing an edge
With your screens arranged to match the desk, move the pointer past the shared edge. The cursor appears on the other Mac and keyboard input follows.
Under Settings → Control & Edges you can tune how edges feel. Edge sensitivity is Light, Medium, or Firm: Light crosses with no dwell, and Firm means the pointer must dwell at the edge longer before crossing. Push-through friction means a deliberate push crosses but an accidental brush does not. Easy edge crossing (on by default) uses the whole edge when it leads to another Mac, and the pointer enters at the nearest shared point. Edge peek makes the far Mac’s edge glow as your pointer approaches.
See Screen arrangement if the layout does not match your desk.
Return to this Mac
Push back across the shared edge you crossed, or press the Return hotkey
(default Globe/fn + \, configurable under Settings → Control &
Edges).
The return hotkey works from any Mac in the mesh, not only the one that originally sent the cursor.
Keep the pointer on one Mac
Press Globe/fn + L to lock the pointer to the Mac it is on, so no edge
crosses until you press it again. Useful for a game that pushes the pointer to
the edge, or for drawing right beside one. See
Lock the pointer to one Mac.
Pointer feel on the remote Mac
Under Settings → Control & Edges → Pointer, set Pointer device to Auto, Trackpad, or Mouse to match the cursor feel to your device. Auto follows the trackpad; pick Mouse if you mostly use a mouse. Trackpad sensitivity is a slider from 30% to 150% (default 100%): lower it if the remote cursor feels too fast. Scroll sensitivity (50% to 150%, default 110%) sets how far the remote Mac scrolls, and applies on the Mac being controlled.
See Trackpad gestures for pinch, rotate, and swipe.
Password fields
While macOS Secure Event Input is active, typically in a password field, Continuo pauses key forwarding. Type passwords locally; they will not leak to a remote Mac. This is enforced under Settings → Privacy & Security and cannot be turned off.
When keys stop forwarding
Check Accessibility and Input Monitoring on both Macs. Input Monitoring may need a relaunch after granting. See Permissions.
