"Macs don't get viruses" is one of the most stubborn beliefs in computing. It was never quite true, and in 2026 it is comfortably out of date, yet it still shapes how a lot of UK businesses protect, or fail to protect, their Apple devices. Let us take the myth apart calmly: where it came from, what is genuinely different about a Mac, and what a sensible business actually needs to do about it.
The myth: where it came from
The belief has a real origin, which is why it stuck. For a long time Macs were a small fraction of the market, so attackers chasing volume wrote for Windows because that is where the machines were. A Mac user genuinely was less likely to encounter malware, not because the Mac was magically immune, but because almost nobody was aiming at it. That is an economics story, not a security one, and economics change.
macOS also does have some genuine architectural defences that Windows historically lacked, which gave the myth a kernel of truth to grow around. The problem is that "safer by default" quietly became "safe", and "less targeted" became "untargetable", in the retelling. Neither leap is justified.
The reality: yes, with an asterisk
Macs absolutely can be compromised, and increasingly are. The honest nuance is in the word "virus". Classic self-replicating viruses are rare on every modern platform now, Windows included, because that is not how attackers make money any more. What targets Macs today is the same family of threats that targets everyone: information-stealing malware that grabs passwords and session tokens, fake software updates, malicious browser extensions, and above all phishing, which does not care what operating system you run.
There is now a steady stream of Mac-specific information-stealer malware sold to criminals as a service, precisely because Apple's share of the business market grew enough to be worth attacking. The threat is real and commercial. It is just shaped differently from the floppy-disk viruses the myth still pictures.
- •Self-replicating 'viruses' are rare on every modern platform, not just Macs
- •Information-stealer malware aimed specifically at macOS is now an active, commercial market
- •Phishing, fake updates and malicious extensions work identically regardless of operating system
- •A larger Apple footprint in business made Macs worth targeting in a way they once were not
What macOS actually protects you from
Credit where it is due: Apple does ship meaningful built-in protection. Gatekeeper checks that apps come from identified developers, the system warns you before running unfamiliar software, apps are sandboxed to limit what they can touch, and there is a quiet built-in malware-removal component that Apple updates behind the scenes. For a careful home user this stack genuinely stops a lot of casual nastiness.
What it does not do is cover the parts that matter most to a business. It will not stop a user being tricked into typing their password into a convincing fake login page, it will not give your IT team visibility across a fleet of devices, and it will not detect or respond to an attacker who is already inside using legitimate tools. Those gaps are about people and management, not about the platform being weak, and they are exactly the gaps a business has to close itself.
What a business should actually do
Treat Macs like any other endpoint, because to an attacker they are. The same security hygiene that protects your Windows estate applies: behavioural endpoint protection that works on macOS, central management so a lost or compromised device can be handled remotely, multi-factor authentication so a stolen password is not enough on its own, and security awareness training, because phishing is the common thread through almost every real incident.
The single most useful mental shift is to stop thinking of "the Mac question" as separate. The threats that hurt UK businesses are largely platform-independent, so the answer is a platform-independent security posture. Our endpoint security service covers macOS alongside Windows, and the wider EDR picture in EDR vs antivirus applies to Apple devices just as much as to PCs.
