Apple has released a major security fix to address SSL security flaw in its Macintosh computers that allows hackers to intercept sensitive information such as email.

Addressing an embarrassing glitch that emerged several days ago, the latest update issue for Apple PCs powered by OS X operating software comes after fixing a similar bug for iPhones, iPads and iPod Touches, which run on iOS software last week.

In addition to fixing a series of problems, the latest update also allows the computers to make and receive voice calls via Apple’s FaceTime videoconferencing service and email.

According to the iPhone maker, the defect was related to the implementation of well-known protocols, as well the way Apple’s software detects digital certificates used by websites to set up encrypted connections.

The latest updates cover the Mac OS X Mavericks OS as well as the older Mountain Lion system.
