In Apple’s website you can see “It Doesn’t get PC Viruses”, the statement is now changed to “It’s built to be safe”, Why? Apple’s world’s most advanced operating system is not immune to virus. Recently Mac’s are attacked by Flashback botnet, and weakness in Java programming gained access to Mac machines.
And another statement Safeguard your data. By doing nothing.” has been replaced by the much gentler “Safety. Built in.” after the attacks on Macs.
Yes, It Doesn’t get PC viruses, It get Mac viruses.
