Best Antivirus for Mac 2026: Do Macs Need It, and Which to Pick

By Thomas Løvaslokøy · Published May 31, 2026 · 9 min read

"Macs do not get viruses" was never quite true, and in 2026 it is a genuinely risky belief. macOS is well defended, but adware, fake installers and infostealers target it every day, and Apple's built-in tools do little against phishing and scam sites. This guide answers whether your Mac needs antivirus, explains how we chose our picks, and links to our full reviews. Our short answer: most Mac users are well served by Bitdefender; for an all-in-one bundle pick Norton 360; and for a free start, try Avast One.

Do Macs need antivirus?

The honest answer is "it depends, but more often yes than Mac folklore suggests." macOS ships solid built-in protection: Gatekeeper checks the provenance of apps, notarization screens developers, and XProtect blocks known malware. That stops a lot. What it does not do well is protect you from phishing pages, scam sites and brand-new threats, and it offers nothing for the adware and fake-updater nuisances that plague Mac users. The threats that actually cost people money today are social-engineering and infostealer campaigns, and those do not care which operating system you run. We unpack the full argument in our guide on whether Macs need antivirus.

How we chose

For Mac specifically, our criteria shift slightly from the Windows world. We prioritise a native, well-tuned macOS build rather than a heavy Windows suite ported across — a badly ported product can hurt performance for little gain. We weigh protection against the threats that actually hit Macs: adware, malicious installers, infostealers and phishing, rather than chasing Windows malware that will never run. Performance and battery impact matter on laptops, so a light footprint counts. And we look at value and useful extras — anti-phishing, a VPN, a password manager — that earn their place without bloating the system. Each pick below links to our full, separate review.

Bitdefender — best for most Macs

Bitdefender's Mac build is light, well-designed and strong exactly where macOS users are exposed: it blocks malicious and phishing sites effectively and catches the adware and infostealers aimed at the platform, without dragging the system down. For the majority of Mac owners who want strong protection they can install and forget, it is our first recommendation. Read the full picture in our Bitdefender review.

Norton 360 — best all-in-one for Mac

If you want one subscription to cover your Mac plus an unlimited VPN, cloud backup and a password manager, Norton 360 is the most complete bundle. It is heavier than Bitdefender, but on a modern Mac that is rarely an issue, and the extras genuinely save money versus buying them separately. The clean interface also makes it a good choice for a family Mac. See our Norton 360 review.

Avast One — best free starting point

If you would rather not pay yet, Avast One's free tier is genuinely usable on Mac, giving you real-time protection and basic web defence at no cost, with a clear upgrade path. Just go in aware of Avast's history, which we cover candidly in our Avast One review. For more on the free-versus-paid trade-off, see our free vs paid antivirus guide.

Common mistakes Mac users make

• Assuming the Mac is immune. It is well defended, not invulnerable — that mindset is exactly what attackers exploit.
• Installing apps from random download sites. Stick to the App Store or trusted developers; fake installers are a leading macOS infection route.
• Ignoring phishing. The biggest real-world risk is a convincing fake login page, and macOS does little to block those — a third-party anti-phishing layer helps.
• Running a heavy Windows-style suite. Choose a product with a native, light Mac build instead.
