You’ve probably heard it before: “Macs don’t get viruses.” For years, Apple’s reputation for security has led users to believe their Macs are immune to malware, phishing, or other online threats. This belief isn’t entirely unfounded. macOS is a secure operating system with several built-in protections. But that doesn’t mean it’s bulletproof.
In recent years, real-world malware targeting Macs has surged. From adware like Shlayer and AdLoad to sophisticated tools like Silver Sparrow and Atomic Stealer, Mac-specific threats are no longer a rarity. They are part of the landscape. Attackers are adapting, evolving, and specifically designing malware to bypass Apple’s native defenses.
Despite Apple’s best efforts, Mac users are still vulnerable to serious threats that can compromise privacy, steal sensitive data, or disrupt daily use, often without any obvious signs. Understanding these risks is the first step toward staying truly secure.
Apple has developed macOS with several layered security features to help keep users safe:
These tools are effective for protecting against known threats and helping prevent basic malware from executing or spreading. However, they are not a complete solution. Gatekeeper, for example, can be bypassed by malware disguised as legitimate software. XProtect is updated infrequently and only catches known malware signatures, not new or emerging threats.
A common misconception is that these protections are enough for daily use. However, they don’t actively block phishing attacks, monitor your network, or offer real-time threat response. They also do little to prevent user-initiated mistakes, like clicking a malicious link or opening a spoofed attachment.
Mac-specific malware has become more advanced and more prevalent. Attackers know that Mac users often assume they’re protected, making them attractive targets. Over the last few years, the following examples illustrate how the threat landscape has changed:
These threats aren’t just hypothetical. They’ve been documented by leading security firms and have infected real Mac users. Importantly, most of them either bypassed Apple’s built-in defenses or were missed entirely until security researchers discovered them.
Hackers are also shifting from brute-force attacks to social engineering—tricking users into installing malicious software themselves, often by disguising it as utility apps, fake system updates, or email attachments.
While Apple’s security features are impressive, they aren’t infallible. Here are a few things they don’t cover:
MacOS provides a strong foundation, but it’s not a complete shield. Relying only on built-in tools leaves gaps that advanced malware can slip through, especially if you use your Mac for work, school, finances, or frequent downloads.
Even cautious users are exposed to modern threats, especially through:
| Threat | Example | Description | macOS Protection? |
| Adware | AdLoad | Signed packages bypass Gatekeeper, flood system with persistent popups | Partially blocked |
| Phishing | Apple ID scam emails | Spoofed emails redirect users to fake login pages to steal Apple credentials | Not blocked |
| Ransomware | EvilQuest | Encrypts user files and installs a keylogger | Not actively blocked |
| Stealer Malware | Atomic Stealer | Extracts browser passwords, crypto wallets, and system files | Undetected by XProtect |
| Fake Utilities | MacCleaner, MacBooster | Pose as legitimate tools, load spyware and push system alerts | Often bypasses Gatekeeper |
Whether you use your Mac for casual browsing or run a business on it, the answer is the same: yes, antivirus software is still recommended. The days of thinking “I have a Mac, so I’m safe” are over.
Even trusted sources can be compromised, verified apps can hide malicious behavior, and smart users can make mistakes.
If you answered yes to any of these, your Mac is exposed to threats that Apple’s default tools may not detect or block.
Dedicated antivirus software like Intego fills the gaps that Apple leaves open:
Unlike Apple’s tools, which are mostly passive, antivirus software works proactively—scanning, monitoring, and blocking threats before they cause harm.
Many users wonder if free antivirus is “good enough.” Here’s what you typically get:
Free tools are often stripped-down versions of paid ones and are rarely optimized for macOS specifically. Some even collect user data to subsidize their free tier.
While any protection is better than none, free tools leave many risks unaddressed:
If you’re serious about your data, privacy, and device security, choosing a solution that offers comprehensive protection built for macOS is worth choosing.
Intego is designed exclusively for macOS, not retrofitted from a Windows product. This means it integrates seamlessly with Apple’s architecture, uses fewer resources, and avoids compatibility issues that other antivirus apps often cause.
Intego provides:
Intego has specialized in Mac security since 1997. It’s backed by:
Get Intego antivirus for Mac today.
Yes, Macs need antivirus protection. The belief that Apple computers are inherently immune to threats is outdated. As malware authors get smarter and Mac usage increases globally, attackers are actively targeting macOS with adware, phishing, and data-stealing software.
macOS provides a solid security baseline, but it’s not enough on its own, especially if you browse the web, check email, or install apps from anywhere other than the App Store.
If you want peace of mind and comprehensive protection built specifically for your Mac, Intego is a smart, proven solution.
Do Macs really get viruses?
Yes. While less common than on Windows, Macs are increasingly targeted. Malware like AdLoad, Silver Sparrow, and phishing campaigns impersonating Apple prove that Mac users are not exempt.
Is macOS security good enough by itself?
No. It protects against known malware and restricts certain app behaviors but doesn’t offer real-time protection, web filtering, phishing defense, or advanced firewall capabilities.
What’s the best antivirus for Mac users?
Intego is purpose-built for macOS. It offers real-time malware scanning, a customizable firewall, phishing protection, and privacy tools—without slowing down your Mac.
Do I need an antivirus if I only use my Mac for browsing?
Yes. Threats, including malicious ads, fake alerts, and phishing pages, can appear during browsing. Visiting the wrong site or clicking the link can trigger an infection.
Can I just use a free antivirus?
You can, but you’ll miss out on real-time protection, phishing filters, support, and deeper system integration. Free tools are limited and don’t offer the comprehensive defense Mac users need today.
Is there a performance trade-off when using antivirus on Mac?
Not with Intego. It’s optimized for macOS and runs efficiently in the background without dragging down performance or interfering with other Apple features.
How often should I scan my Mac for viruses?
With real-time protection enabled, scanning once a week is typically enough. However, you should scan immediately after downloading files from unknown sources or if you notice unusual behavior.
