Do I Need Antivirus on Mac in 2026?

macOS ships with Gatekeeper and XProtect, which block a meaningful share of known malware before it ever runs. So do you still need a separate antivirus?

What macOS already protects against

Gatekeeper checks app signatures before launch, and XProtect uses Apple's own signature database to catch known malware. This handles a lot of the most common threats automatically.

What it doesn't cover

Phishing links, malicious browser extensions, cross-platform threats (like malicious Office macros that could also affect Windows users you share files with), and newer malware not yet in Apple's signature database.

When a dedicated antivirus makes sense

If you: handle sensitive work files, share documents with Windows users regularly, browse unfamiliar sites, or just want an extra layer of real-time and web protection — a dedicated tool adds real value. See our Best Antivirus for Mac picks.
