The recent ruckus about the claimed growing vulnerability of Mac OSX from certain sources has caused an indignant outcry from Mac advocates who claim the stories are mostly media hype. According to an expert in Unix and Linux systems, the outcry is not without justification. Con Zymaris has been working with Unix systems for nearly three decades and for the past 15 years has been running a consultancy on open source software implementation. Zymaris says that, while it is true that a Mac can get infected with a virus, it is not easy and it is not likely to cause much damage. What’s more, Mac users don’t need to install firewalls and anti-virus software.
