Macs Aren't Immune: The Rise of Mac Malware in 2026 — and How Moonlock Helps
Most people still think Macs are safe - but Mac malware, especially infostealers, is rising fast. What macOS does and doesn't protect against, and how Moonlock, MacPaw's AV-TEST-certified Mac security app, closes the gap. Plus the honest caveats before you buy.

"Macs don't get viruses" was never quite true, and in 2026 it's a genuinely risky thing to believe. Mac users are being targeted more than ever — yet most still assume the platform quietly protects itself. Here's what's actually happening to Mac security, what macOS does and doesn't cover, and where a Mac-first security app like Moonlock fits.
The myth vs. the 2026 reality
macOS has real built-in defenses, and they're better than nothing — but they were never designed to be a complete security suite. Meanwhile, attackers have noticed the "Macs are safe" assumption and lean into it.
According to Moonlock Lab (MacPaw's security research team), the numbers moved sharply the wrong way: roughly two-thirds of Mac users encountered a cyberthreat in 2025, backdoor malware rose about 67% year over year, macOS stealer malware grew ~17%, and victims turned up in more than 80 countries. Those are the vendor's own research figures, so take them with the usual grain of salt — but they line up with a clear industry trend: the Mac is now a big enough target to be worth attacking.
The category that should worry everyday users most is the infostealer — malware that quietly harvests passwords, browser cookies and crypto wallets. If you're not sure what that means, our explainer on what an infostealer is is a good primer, alongside the basics of how ransomware starts and how to spot fake tech-support popups.
What macOS covers — and what it doesn't
Apple's XProtect and Gatekeeper, plus app notarization, block a lot of known-bad and unsigned software. But they're largely reactive and signature-based: they don't give you continuous real-time scanning, a view of what's talking to the internet, or scam detection. That gap — between "blocks known threats" and "actively watches your machine" — is what third-party Mac security is for. (If the difference between antivirus, VPNs and password managers is fuzzy, our antivirus vs VPN vs password manager guide untangles the layers.)
What Moonlock is
Moonlock is MacPaw's dedicated Mac security app, built by the team behind CleanMyMac with well over a decade of Mac software experience. It launched in October 2025, and — importantly — it's AV-TEST certified and Apple-notarized, meaning it's been independently tested and vetted. It's not a Windows antivirus ported to the Mac; it's built natively for macOS.
The app is organized into six areas:
- Malware Scanner — the centerpiece: real-time "Active Protection" plus on-demand scans, working alongside macOS XProtect and Gatekeeper rather than fighting them.
- VPN — a built-in VPN that tested clean (no DNS or WebRTC leaks) with a no-logs policy.
- Network Inspector — see what apps and connections are reaching the internet.
- System Protection and a Security Advisor — ongoing checks and plain-language guidance, including help spotting scams and risky sites.
- A Home dashboard tying it together.
Because it's Mac-first, it stays light and native rather than bogging the machine down — the kind of thing that matters if you've ever run a clunky cross-platform antivirus.
The honest caveats
- The scary stats are the vendor's own research. Directionally credible and consistent with the wider trend, but they come from the company selling the fix — read them as "the threat is real and rising," not gospel.
- No antivirus is a silver bullet. Moonlock augments macOS and good habits (prompt updates, careful downloads, multi-factor auth); it doesn't replace them. Start with the fundamentals in how to secure a new Mac on day one.
- The built-in VPN is a bonus, not a full replacement. It's genuinely useful for public Wi-Fi, but if a feature-rich VPN is your priority, a dedicated one still goes further.
- It's low-risk to try. There's a 7-day free trial and a 30-day money-back guarantee, with monthly, annual and one-time lifetime plans — enough runway to see whether it earns a place on your Mac.
Who it's for
- Everyday Mac users who want real-time protection beyond the built-in basics — especially if you bank, shop or work on your Mac.
- People who prefer one clean native app over juggling a separate antivirus, VPN and network tool.
- It's less essential if you're highly technical with an already locked-down setup — though the scanner still catches things good habits alone can miss.
Bottom line
The "Macs are immune" era is over. They're safer than the average PC, but increasingly targeted — and the built-in tools weren't meant to be a full security suite. Moonlock is a credible, Mac-first way to add real-time protection without slowing your machine: independently AV-TEST certified, Apple-notarized, from a long-standing Mac software team, with a free trial and refund window so you can test it risk-free. Pair it with sensible habits and you've closed most of the gap the "Macs are safe" myth left open.
