What to do when the Mac Dock keeps moving to another display: direct answer

A Dock that keeps moving is usually tied to edge gestures, display layout, and full-screen workflows, so start by recording triggers.

Decision: Dock movement between displays is commonly triggered when the pointer reaches another display's bottom activation area. Record display geometry, Dock position, and the exact pointer path before choosing a fix.

Steps for What to do when the Mac Dock keeps moving to another display

  1. Map the left/right or above/below display arrangement and record the main display and Dock edge.
  2. Without the utility, reproduce three to five times and record pointer path, full-screen state, and frequency.
  3. Enable DockLocker, grant the required permission, and repeat with the same layout and pointer path.

How to verify the result

  • Trigger counts before and after are comparable and Command-Tab, full-screen, and display switching gain no new conflict.
  • Retest after sleep/wake, reconnecting displays, and restart instead of relying on one session.

Limitations and stop conditions

macOS imposes its own display-geometry and Dock-placement limits, so no utility should promise every arrangement works.
