In most cases, Mac Book Pro users use a cover/skin to protect their computers from dirt & external damage. Maclocks security cover is a simple, yet clever solution which incorporates a security slot into the actual Mac Book Pro cover. This smart skin mechanism slightly elevates the Mac Book Pro above the surface, thus enhancing current venting system. The polymer security cover is engineered to support the Mac Book Pro cooling process. Once the case & cable are locked together, it's hard to detach the case without damaging the Mac Book Pro. This makes the Mac Book Pro with Retina display Lock flexible & light, not to mention stylish, so you can easily take it with you wherever you go.
