Intego vs macOS Built-in Security (2026): Do Mac Developers Need AV?

macOS ships real protections — XProtect signature scanning, Gatekeeper, notarization, TCC permissions — and they stop commodity threats well. What they don't give you: real-time behavioral scanning, a visible outbound firewall, or scheduled full-disk scans. Intego adds exactly those. The honest calculus for a developer: your laptop holds SSH keys, cloud consoles, and client production access — you're a high-value target for infostealers, which are the actual Mac malware wave. If you install from outside the App Store, run npm/pip packages daily, or hold client credentials, the marginal protection is defensible. If your Mac is App-Store-only email-and-browser, the built-ins are probably enough. Either way: FileVault on, and watch what NetBarrier-style outbound prompts teach you about your own machine.

Intego in short

Mac-native security: antivirus (VirusBarrier), firewall (NetBarrier), plus backup and cleanup tools — one of the few vendors that has always been Mac-first. Annual plans by bundle (Mac Internet Security vs Premium with backup/cleanup).

Verdict

Match the tool to the job above; if still torn, run both against one real week of work — that answers it faster than any review.
