Apple released a patch of a serious iOS security flaw on Friday. Five days later, that bug is still very much present in OS X, meaning your MacBook is more at risk than ever. Apple says it’s aware of this issue and already has a software fix “very soon,” but declined to go into further detail. If you have an iPhone, you should update to iOS 7.0.6.6 immediately, you don’t have that option if you have a MacBook, you still run the risk of being violated.”]
