MacLocks has released the first locking mechanism for the new MacBook Pro with Retina Display. This new lock is a notable product release because the new MacBook Pro with Retina Display lacks the built-in Kensington lock adapter that is present on the last-generation MacBook Pro design. Since the lock slot isn’t present on these new MacBook Pros, the MacLocks kit comes with a polymer shell that sits on the bottom of the MacBook Pro, and their locking system attaches to this. MacLocks says the bottom piece is not removable without damage to the computer. The company also says that the bottom piece improves cooling for the notebook, and a MacBook Air model is available as well. The locking kit is available for pre-order at $69.95.
