In most cases,MacBook Pro users use a cover/skin to protect their computers from dirt and external damage. Maclocks security cover is a simple,yet clever solution which incorporates a security slot into the actual MacBook Pro cover. 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. Once the case and cable are locked together,it's hard to detach the case without damaging the MacBook Pro. This makes the MacBook Pro with Retina display Lock flexible and light,not to mention stylish,so you can easily take it with you wherever you go.
