RUSTAMGULOFFBlockDock
A macOS menu-bar utility that fixes one small but maddening problem: with multiple displays, the Dock jumps to whichever screen your cursor lingers at the bottom of. macOS has no built-in "pin Dock to display" setting.
How it works
BlockDock watches the cursor via CGEventTap and places an invisible barrier — a few pixels tall — along the bottom edge of the displays where the Dock shouldn't live. The cursor can't "stick" to the bottom of those screens, so macOS never moves the Dock there.
- Never touches windows or clicks — cursor only
- Pick the Dock's display, or use Auto mode
- Adjustable barrier height (2–20 px)
- Launch at login
