For countless years, Apple insisted that their operating system is safer than ones running competing operating systems such as Microsoft Windows or Linux. At the same time, Apple was one of easiest systems to break in (firewall disabled by default) and now, with egos wounded (and legally liable) from Flashback botnet, a change happened.
Apple gathered a lot of negative press in terms of security, with hackers and crackers gaining access to the user files within half a minute, becoming a running joke of conferences such as Defcon.
Still, the company rode the wave of "I'm a Mac and I'm a PC" focusing on the "fact" that Windows-based PC systems get viruses, while OSX-based PC systems cannot (be inflicted). With the fact not being true anymore, and Flashback botnet destroying the sense of security for the already insecure platform – Apple did what it does the best – deploy its legal system to remove any traces of potential liability for the company.
In a story that spread thanks to Australian version of Computerworld, a security blog Naked Security by Sophos discovered that Apple has changed its security policy, as you can see on the picture below:
The company is slowly changing its approach to security, with Geniuses in Genius bars recommending Anti-Virus products, security guides for mobile operating system iOS (iPhone, iPad, iPod). Furthermore, do you remember User Account Control (UAC), a controversial security routine which debuted with Windows Vista, continuing its existence with Windows 7 and Windows 8 as well? UAC was designed to prevent users from installing different application types, restricting access to websites and so on and so forth.
Well, Apple users will get the same dosage of security – the 10.8 version of the OS X codenamed "Mountain Lion" will bring a similar feature, an "Apple-ized" version of Microsoft's UAC named "Gatekeeper".
At the end of the day, attacking other platforms based on your claim of security is something that will only bring attention and provoke people from other side of computing specter.
