Lock your Dock.

No. DockLockr is a one-time purchase — you pay once and own your license, with free updates included. The only recurring thing is the peace of mind. You can try it free for 3 days before buying.

To lock the Dock properly, DockLockr needs a little more access than App Store sandboxing allows. We distribute it as a signed and notarized .dmg directly instead — so it's still checked by Apple for security, with no sandbox compromises that would water down what the app can do.

Yes. The Pin Dock to a Screen feature is built for multi-monitor setups: pick the display you want, and DockLockr keeps the Dock there instead of letting it hop to whichever screen your pointer drifts toward.

It goes back to normal. DockLockr always unlocks the Dock cleanly when it quits — it never leaves your Dock frozen. There's also a one-click Reset Dock that restores everything immediately, so you're never stuck.

Yes. A single license activates on up to 3 devices, so you can run DockLockr across your machines. Retiring an old Mac frees up a slot for the new one.
