Charlie Miller says Macs are less secure for the reasons of lack of anti-exploitation technologies, but are more safe because there simply isn’t much malware out there. Miller: “For now, I’d still recommend Macs for typical users as the odds of something targeting them are so low that they might go years without seeing any malware, even though if an attacker cared to target them it would be easier for them” Whatever OS you’re running, the best thing you can do is to just keep your system up to date.”]
