Antivirus company Sophos highlighted the change to Apple's "Why you'll love a Mac" webpage, noting that the previous claim that Mac OS X doesn't get PC viruses has been removed, replaced by the statement: "It's built to be safe."
Previously, the web page said: "It doesn't get PC viruses. A Mac isn't susceptible to the thousands of viruses plaguing Windows-based computers. That's thanks to built-in defences in Mac OS X that keep you safe without any work on your part."
"With virtually no effort on your part, OS X defends against viruses and other malicious applications, or malware," the Apple's web page continued.
Now, though, the same web page has been changed to read: "It's built to be safe. Built-in defences in OS X keep you sage from unknowingly downloading malicious software on your Mac."
"OS X is designed with powerful, advanced technologies that work hard to keep your Mac safe," the page now reads.
