So I understand that some of you worry that Mac Defender is a
scary sign of things to come. But while the Mac security situation
really is changing, those changes are due almost entirely to
attackers’ changing tactics and have little to do with the
inherent strength or weakness of Mac security. The bottom line:
You should pay attention to Mac security. But you don’t need to
freak out about it.
Smart, rational look at the state of Mac malware.
