It's a tale as old as computing itself: Macs can't get viruses. It's not true, but a new survey by security site All About Cookies seems to indicate that far too many macOS users believe their systems are immune, even though they're security-conscious about other aspects of computing—at least, compared with Windows users.

The survey of 1,000 US adults, conducted in June, asked a series of security-related questions. For the most part, users of both major platforms seemed to have issues at about the same rate, from viruses or malware to overall computer-repair problems. But when asked about the tools they use to keep their computers safe, far more Windows users than Mac users have installed antivirus, firewalls, and anti-spyware tools.

More Mac users have embraced multi-factor authentication, ID theft protection, password generators, VPNs, and biometrics. Yet Windows users are more likely to jump on getting system updates installed ASAP.

The only tool where there's parity is password managers: 32% on both sides report using them. (That's still a tragically small amount.)

Again, these aren't numbers to crow about, since system updates are so important to maintain security. But many people are wary, since we've been burned before.

Back to that antivirus-usage dichotomy: All About Cookies also asked questions designed to find out which security and safety issues survey respondents have encountered on their systems. At the top of the list is that almost half of each OS group has contracted a virus.

The platform with the higher number of virus encounters? Mac users. That's right, the same group in which only 34% claim to install antivirus software. It's seriously time to rethink that position.
