macOS “Cannot Verify That This App Is Free From Malware”? Fix the Error

Описание: Seeing the warning “macOS cannot verify that this app is free from malware” can be confusing — and a little scary. In this video, we break down exactly what this message means, why it appears, and what you should do next to keep your Mac safe.

If you’ve run into alerts like “Mac cannot verify that this app is free from malware,” “this app cannot be opened,” or “this application cannot be opened” error on Mac, you’re not alone. These messages are part of Apple’s built-in security system called Gatekeeper. When macOS can’t confirm the developer or source of an app, you may see variations like “macOS can’t verify app is malware free,” “Apple could not verify is free of malware,” or “this app cannot be opened Mac.”

In this guide, we explain:
why the “macOS cannot verify app is malware free” warning exists
when it’s safe (and not safe) to bypass it
a "macOS cannot verify app is malware free" error quick fix using System Settings
the real risks of installing apps from unknown sources

Just because you see this message doesn’t automatically mean the app is malicious — but it does mean you should be cautious. Malware is increasingly targeting Macs, and attackers often hide threats inside seemingly normal apps.

That’s why we recommend running dedicated Mac security software. Moonlock scans every file you open, detects hidden malware, and helps keep your system secure even if you accidentally approve a risky app.
