In most cases MacBook Pro users, use a cover / skin to protect their computers from dirt and external damage. The Maclocks security cover (patent pending) is a simple, yet clever solution which incorporates a security slot into the actual MacBook Pro cover (Only adds 0.35lbs when using the lower skin and 0.7lbs when using it as a shell) a similar solution is offered for the MacBook Air. This smart skin mechanism, slightly elevates the MacBook Pro above the surface thus enhancing current venting system.
The polymer security cover is engineered to support the MacBook Pro cooling process. That way you can lock the security cable to the MacBook Pro case and loop the cable's other end around a fixed object such as a table leg. Once the case and cable are locked together, it's hard to detach the case without damaging the MacBook Pro. This makes the Maclocks MacBook Pro Lock 13" Retina Display Security Lock, flexible and light, not to mention stylish so you can easily take it with you wherever you go.
