“Macs don't get viruses”
Verdict: False
They do. Less malware is written for macOS, largely because it runs on fewer desktops — that's a different claim.
macOS has real malware and has had it for years. Info-stealers aimed at Mac users are an active, commercially motivated category, and Apple ships XProtect and Gatekeeper precisely because the threat is real.
What is true is that less malware targets macOS than Windows. The main reason is arithmetic: Windows runs on a far larger share of desktops and attackers follow the numbers. Apple's tighter default permissions genuinely help as well.
The failure mode this myth creates is the dangerous part. Someone who believes they are immune is someone who will approve a malicious installer prompt without reading it.

The house is not going to pretend Windows is the safer platform. It isn't. But safer and immune are different words, and the second one gets people robbed.
