I heard Macs don't get infected — do I still need protection?
The belief that Macs don't get malware is outdated. It was a reasonable approximation when macOS had a small market share and attackers focused on Windows. That period ended. macOS is now a primary target for adware, PUPs, browser hijackers, ransomware variants, and credential stealers — and several of those threat categories are built specifically for the platform rather than ported from Windows.
Quick answer
When it matters
The threats that most commonly affect macOS in practice:
- Adware and browser hijackers — installed as bundled software alongside legitimate downloads; redirect search engines, inject ads, persist through browser reinstalls
- PUPs (Potentially Unwanted Programs) — presented as system cleaners, optimization tools, or PDF converters; collect data, slow the machine, and are difficult to fully remove manually
- Ransomware — less common on macOS than Windows, but documented variants exist including LockBit macOS builds; targets creative professionals with high-value file archives
- Credential stealers — macOS-targeted malware that extracts Keychain passwords, browser cookies, and crypto wallet data
- Fake AV and scareware — popup notifications claiming the Mac is infected, designed to collect payment or install additional malware
The most common entry point across all categories is the user installing something that looks legitimate. Gatekeeper can be bypassed by software distributed through third-party sites. That gap is where most macOS infections originate.
When it fails
- Browser-based attacks — malicious JavaScript, drive-by downloads, and session hijacking happen inside the browser, where AV has limited visibility
- Phishing — entering credentials on a convincing fake login page is a human decision; no AV intercepts it at the point of entry
- iOS devices — AV does not run on iPhone or iPad due to Apple's sandbox model; 'Mac protection' does not extend to mobile
Software hygiene addresses the largest remaining gap: installing only from the Mac App Store or verified publisher sites, keeping macOS updated, and not dismissing Gatekeeper warnings without understanding what they mean. An AV product adds a detection layer on top of that foundation — it doesn't replace it.
How providers fit
Bitdefender fits if you want ongoing real-time protection on macOS. The macOS client includes behavioral detection alongside signature scanning — it's not a reduced version of the Windows product. Autopilot mode removes the need to interact with it after setup.
Malwarebytes fits if the goal is a one-time check rather than ongoing protection. The free on-demand version has strong macOS adware and PUP detection — specifically the categories most commonly found on Macs. Run it if the machine has been showing browser-related symptoms or if you've installed software from outside the App Store recently.
F-Secure fits if you want quiet ongoing protection without data collection. Real-time macOS scanning, no telemetry beyond security events, no data monetization policy. Lower profile than Bitdefender, but effective and appropriate for users who prioritize software trust alongside threat coverage.
Macs need protection — the threat category has matured. Bitdefender for comprehensive ongoing coverage. Malwarebytes Free to check the current state without committing to a subscription. F-Secure if the privacy posture of the AV software itself matters alongside the protection it provides.
