Kensington Security Slot and Lock for Laptops are intended to deter or to some extent prevent stealing of Windows based Laptop or MacBook Pro with steel cable. It is officially known as the Universal Notebook Security Cable. Windows based laptops are practically a joke by build, but this Kensington Security Slot actually has a metal plate extension to the only one metal board on which all the things are actually screwed, in some models. For some devices, the holes for the lock are machined only in plastic, so that breaking out is very simple.
For MacBook Pro, definitely Kensington Security Slot with lock is a real pain for the thief to steal but unfortunately MacBook Pro with Retina Display right now has no Kensington Security Slot to hold the loop.
