Is there a Dock locker for Mac?
Yes. The app most people mean when they search “Dock Locker for Mac” is DockLockr, spelled without the second “e”. It is a native macOS menu-bar app that locks the Dock against accidental changes, with three independent toggles: Lock Dock Items stops pinned apps being added, removed or reordered; Lock Dock Size makes the Dock's resize divider inert; and Pin Dock to Screen keeps the Dock on one display on a multi-monitor Mac. DockLockr costs $9.99 one-time, requires macOS 15 or later on Apple Silicon, and has a 3-day free trial. Quitting the app unlocks the Dock cleanly.
