Dock Locker


A simple utility to keep icons from being dragged out of the Macintosh dock. Whether on accident or (as in our case) students just love to watch the "poof" of disappearing icons, Dock Locker will keep your icons in place until the dock is unlocked. Optionally, it will also keep the dock from being resized or repositioned and can require a password when the app first opens.
Free:   There are no in-app purchases or advertisment banners.

"I have just come across your application, Dock Locker Varsity, and it is just fantastic. I teach in a nursery school in Bradford, UK and we use managed account for the children with 'some limits' and a Simple Finder appearance. Until Dock Locker, in order to change the apps available to children in the Dock, we have had to lock and unlock the Dock through the Account preferences, logging in and out for the changes to take effect and putting in admin passwords repeatedly. Dock Locker will not only save us all time, but make it much, much easier for all staff to vary the apps available to children on a regular basis. Thanks for a really useful app."
