How To Fix “MacOS Cannot Verify That This App Is Free From Malware” Error?

If you’ve ever tried to install an app on your Mac and received the message “macOS cannot verify that this app is free from malware,” you’re not alone. This error is becoming more common as Apple tightens its security. But does this mean every app showing this warning is dangerous? Not always. In this guide, we’ll explain why this message appears, how to bypass it safely, and what businesses—especially VPN resellers—should do to avoid it.

Why Does macOS Show the “Cannot Verify That This App Is Free From Malware” Warning?

Apple’s Gatekeeper system blocks apps that aren’t signed or notarized by Apple. This means if an app is downloaded from outside the App Store and hasn’t gone through Apple’s checks, it will trigger this message.

Common causes include:

• Apps from small developers or open-source projects.
• Tools shared internally within companies.
• Older apps that haven’t been updated to meet Apple’s notarization process.

Common Messages You Might See

• Cannot be opened because the developer cannot be verified.
• Cannot be opened because Apple cannot check it for malicious software.
• macOS cannot verify that this app is free from malware. (XAMPP)
• Apple cannot verify that Sequoia is free from malware.

These are all related to the same Gatekeeper security measure.

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

Here’s a quick and safe way to open apps blocked by macOS without turning off important security settings.

1. Open the App Using Finder (Safe Bypass)

• Right-click on the app in Finder.
• Click Open.
• A warning will appear, but you’ll now see an Open button.
• Click Open again to launch the app. macOS will remember this choice for next time.

3. Check for a Notarized Version

4. Verify App Source

Before bypassing:

• Confirm you downloaded it from the official site.
• Check any checksums (if available).
• Contact the developer to ensure its safety.

What Not to Do to Fix This Error?

• Don’t disable Gatekeeper entirely.
  Although there are ways to disable Gatekeeper via Terminal, this weakens your Mac’s security and leaves you open to actual malware.
  
• Avoid using random scripts or online “fixes.”
  Many “fix” tools found online are actually malware. Stick to Apple’s official recommendations and methods.
  
• Don’t trust any app unless you’re sure of its source.
  If you’re not 100% confident about where the app comes from, don’t bypass the warning.

What if You Keep Seeing This Error with Many Apps?

If you’re constantly seeing this error for many different apps, check:

• Are you downloading apps from trusted sources?
• Is your macOS version up to date?
• Do you need to adjust security preferences (without disabling Gatekeeper completely)?

You can check security settings by going to:
System Settings > Privacy & Security > Security
Look for the “App Store and identified developers” option — this is usually the safest setting.
