"The only thing which has kept Mac OS X relatively safe up until now is the fact that the market share is significantly lower than that of Microsoft Windows or the more common UNIX platforms.… If this situation was to change, in my opinion, things could be a lot worse on Mac OS X than they currently are on other operating systems, regarding security vulnerabilities," said Archibald.
Archibald said his opinion is justified because Apple does not use software auditing tools to scan enough of its software. These types of tools have been heavily employed by Microsoft since the company launched its Trustworthy Computing initiative, in order to discover simple coding mistakes that could allow, for example, buffer overflow errors.
