Three locks. Total control.

Each lock is an independent toggle. Use one, use all three — your Dock, your rules.

Lock Dock Items
Stop apps from being added, removed, or rearranged. A stray drag won't shuffle your layout ever again — your Dock stays exactly as you arranged it.
Lock Dock Size
Pin the magnification and size you like. No more accidentally grabbing the divider and resizing the whole Dock mid-workflow.
Pin Dock to a Screen
Running multiple monitors? Keep the Dock on the one display you chose, so it never jumps to another screen when you move your cursor.

Up and running in under a minute.

No setup, no menus to dig through. Three steps and you're locked in.

  1. 1

    Download & open

    Grab the signed, notarized .dmg and drag DockLockr to Applications. It lives quietly in your menu bar as a small lock icon.

  2. 2

    Flip the locks

    Open the menu and toggle Lock Items, Lock Size, and Pin to Screen — individually, in any combination you want.

  3. 3

    Done — it stays locked

    Launch at login keeps your locks in place day to day. Quit anytime and DockLockr unlocks the Dock cleanly behind it.

One price. Yours forever.
