From the developer:
Allows registered IconDropper users to "lock" or write protect ID packs so that the author information and custom pack art cannot be altered or modified. ID packs can be dragged and dropped onto the utility to launch it, and then, through a simple user interface, the author specifies if the pack should be locked or unlocked.
You may want to check out more software for Mac, such as Mask-R-Aid or IconCreater, which might be similar to IconLocker.
