Short answer: probably yes. But not for the reasons the antivirus industry wants you to think.

I've been using Macs for years. I've heard the same lines everyone has: "Macs don't get viruses." "macOS is secure by design." "You only need antivirus if you're on Windows."

These were debatable ten years ago. In 2026, they're just wrong.

The myth

The idea that Macs can't get malware comes from the early 2000s, when Macs had maybe 3% market share. Attackers didn't bother writing malware for a platform nobody used.

That's changed.

Mac market share has grown significantly. MacBooks are standard in startups, creative industries, and increasingly in enterprise. Where users go, malware follows.

What's actually out there

In the past two years alone:

  • Adware and PUPs (potentially unwanted programs) are the most common Mac threats. They hijack your browser, change your search engine, inject ads, and redirect your traffic. They're annoying more than dangerous, but they're everywhere.
  • Ransomware targeting macOS exists and has increased. It's still less common than on Windows, but it's no longer theoretical.
  • Infostealers — malware that grabs saved passwords, browser cookies, and cryptocurrency wallet data — are growing fast on macOS. These are often distributed through pirated software or fake app downloads.
  • Nation-state malware targets Mac users in specific industries. If you're a journalist, researcher, or work in sensitive fields, you're a target regardless of your OS.

What Apple gives you

macOS has built-in security layers:

  • XProtect — Apple's built-in malware scanner. It checks files against a database of known malware signatures. Updated silently in the background.
  • Gatekeeper — blocks apps that aren't signed by identified developers or from the App Store.
  • Notarization — Apple scans submitted apps for malware before allowing distribution.
  • System Integrity Protection (SIP) — prevents modifications to core system files.

This is solid. Better than what Windows offered for most of its history. But it has gaps:

  1. XProtect's signature database is smaller than dedicated antivirus products. Apple doesn't publish detection rates, and independent tests suggest it catches fewer threats than commercial scanners.
  2. There's a delay. When new malware appears, Apple takes time to add it to XProtect. During that window, you're unprotected.
  3. Gatekeeper only checks apps on first launch. If malware updates itself after initial launch, Gatekeeper won't catch it.
  4. No real-time file monitoring. XProtect scans at specific moments (app launch, file download), not continuously.

The antivirus problem on Mac

So you need additional protection. But here's where it gets complicated.

Most antivirus products for Mac were designed for Windows and ported over. They come with the same baggage:

Heavy system impact. Norton and McAfee noticeably slow down macOS, especially on older machines. Constant background scanning, browser extensions, menu bar clutter.

Privacy concerns. Everything I've written about antivirus data collection applies on Mac too. Norton, McAfee, Avast — their privacy policies don't have a special Mac exception. If they collect browsing data on Windows, they collect it on Mac.

Bundled junk. VPNs you didn't ask for. Password managers you won't use. "PC cleanup" tools that are meaningless on Mac. Browser extensions that monitor your web traffic.

Aggressive upselling. Pop-ups telling you your Mac has "critical threats" that can only be fixed by upgrading to the premium tier. This borders on scareware.

What I actually recommend

You need something that fills XProtect's gaps without becoming a bigger problem than the threats it's protecting you from.

What matters:

  1. Real-time file monitoring — catches threats XProtect misses.
  2. Low system impact — shouldn't slow down your Mac.
  3. No data collection — your antivirus shouldn't be a privacy liability.
  4. No bloat — just scanning, nothing else.

ClamAV checks most of these boxes. It's the open-source scanning engine that's been around since 2002, maintained by Cisco Talos, and listed in CISA's catalog of no-cost security tools. Email servers worldwide use it as their standard malware scanner.

ClamAV's limitation has always been usability — it's a command-line tool. Great for servers, not great for most people.

XorShield AV is built for exactly this — a native desktop app with its own on-device detection engine, real-time monitoring, drag-and-drop scanning, and automatic quarantine. The app makes no network connections beyond downloading signature updates. No data collection, no account required. You can verify the network behavior yourself with Little Snitch or LuLu.

The honest take

Do you need antivirus on Mac? Yes, if you want to cover XProtect's blind spots. New malware that hasn't been added to Apple's database yet. Files downloaded from outside the App Store. USB drives from other people's computers.

Do you need Norton or McAfee on Mac? No. You need a file scanner, not a surveillance platform.

Pick something lightweight that respects your privacy and does one job well. Whether that's XorShield AV, ClamXAV, or just running ClamAV from the terminal — the important thing is adding a layer that Apple's built-in tools don't provide, without adding a layer that watches everything else you do.
