Mac OS X: Free download Dock Unlocker puts an end to accidentally removing app shortcuts from the dock and not realising it until you see the puff of smoke. The app allows you to lock and unlock the dock with a single click, thanks to a dashboard widget.In Windows, you can lock down the taskbar just by right-clicking on it. In Mac OS, there's no built-in way to do the same. Dock Unlocker is a dashboard widget that can do it, and only has two buttons: locked, and unlocked. When it's locked, you'll never have to worry about accidentally removing an app and forgetting which one it was, or accidentally re-ordering the icons or folders in the dock ever again.
Click the closed lock to prevent any changes to the dock, including app removals, additions and resizes. Since Dock Unlocker is a dashboard widget, it runs quietly in the background and doesn't have to be added as a login item. Do you have a better way to keep the dock under control?
