Fix “macOS cannot verify that this app is free from malware”

If you’re a Mac user, you may have encountered the “macOS cannot verify that this app is free from malware” error message when attempting to open some applications.

This message is a key part of Apple’s security measures to protect macOS from malicious software.

Understanding why this error occurs and how to bypass it safely can help you make informed decisions while ensuring the security of your system.

In this post, we will explore the causes of the “macOS cannot verify that this app is free from malware” error, how to resolve it, and, most importantly, how to protect your Mac from unverified apps and other security threats.

Why some Mac apps cannot be opened or verified?

Mac OS includes various settings to protect users from unverified developers and unknown sources.

When you attempt to open an app downloaded from the Internet, especially from an unidentified developer, you might see a message that MacOS cannot verify that the app is malware-free.

This is because Apple has not been able to confirm the app’s source or the developer as part of its security protocols.

Mac apps on the App Store are constantly checked for malicious content and deemed safe for many Mac users. However, apps from outside the App Store may not always undergo the same scrutiny.

MacOS Catalina and later versions are even more stringent about opening apps from unidentified developers. While this feature is essential for protecting your system, it can sometimes block legitimate apps without Apple’s verification process.

What can cause the “macOS cannot verify that this app is free from malware” error?

Several factors can trigger the “macOS cannot verify that this app is free from malware” error when you open apps for the first time:

• Unidentified Developer: When an app is created by a developer who isn’t registered with Apple or verified, the OS will flag the app as unverified.
• Expired Certificates: Even legitimate apps can prompt this error if the app’s security certificates are outdated or no longer valid. This can happen if the developer fails to renew the certificates.
• Downloaded from the Internet: macOS is built to prioritize software from the App Store or trusted sources, so if you download and install apps from third-party sites, you’re more likely to encounter this error.
• Stricter Security Settings: The default settings limit the installation or opening of apps for those from identified developers. Apps from other sources automatically trigger the error message unless you adjust these settings.

This error message reminds us always to be cautious about where our apps come from and ensure the app we’re trying to open is from a trustworthy source.

Can I open an app macOS cannot verify?

Whether you should open an app that macOS can’t verify depends mainly on where you downloaded it.

If the app comes from a trusted source, like the Mac App Store or the developer’s official website, it’s generally safe to proceed despite the warning from Gatekeeper.

However, if the app was downloaded from an unfamiliar or unverified source, it’s best to be cautious and avoid opening it to protect your Mac from malicious software.

How to get rid of the “macOS cannot verify that this app is free from malware” error?

When you encounter this warning, it’s essential to understand that macOS is trying to protect your system from potentially malicious software.

However, if you are sure the app is from a legitimate source, and unverified developers don’t necessarily mean the app is harmful, you can bypass this warning.

To open an app that macOS has blocked:

1. Open Finder and locate the app icon of the blocked software.
2. Control-click (or right-click) the app and click Open from the context menu. This method works differently from simply double-clicking it.
3. When the error message reappears, you’ll now have the Open option.
4. Enter your admin credentials (admin name and password) to authorize the action if prompted.
5. The app will now launch, and macOS will remember this choice.

By following these steps, you are instructing macOS to bypass the safety protocols for this specific app, enabling you to run it even if it isn’t from an identified developer.

Remember, bypassing this feature should only be done for apps that you are certain come from a trusted source.

• Download apps from trusted sources: Download apps from a reliable source like the Apple App Store or the official website of the app developer. Apps from unknown sources may contain potentially harmful software.
• Keep macOS and your apps up to date: Regularly updating macOS and installed apps helps protect your Mac with the latest patches and improvements from Apple. These updates are designed to address vulnerabilities that could be exploited by malware.
• Enable macOS Gatekeeper: Gatekeeper ensures that only programs from a registered developer or the App Store can run, reducing the risk of a malware attack.

How to open unverified apps without compromising security?

Your Mac’s default settings aim to protect you by only allowing programs from the Apple App Store and identified developers.

However, you can adjust these settings to your personal needs:

1. Open System Settings and click Privacy & Security.
2. Under the Allow apps downloaded from, select Anywhere.

Note: If you do not see the Anywhere option, you need to disable GateKeeper. To do this, open Terminal and type the following command: sudo spctl --master-disable. Press Return and enter your admin password when prompted. Now, you should see the third option.

Keep in mind that changing these preferences can potentially expose your system to risks, so do it at your own risk.
