‘macOS cannot verify that this app is free from malware’ fix

If you’re a Mac user, you might have come across the error message macOS cannot verify that this app is free from malware when opening an app.

This warning is part of Apple’s security measures to protect your system from malicious software.

Understanding why this error occurs and how to bypass it safely can help you use your Mac more effectively while keeping your device secure.

In this article, we’ll explore the reasons behind this message, how to resolve it, and tips on protecting your Mac from unverified apps and potential malware threats.

Why does “macOS cannot verify that this app is free from malware” appear?

Mac OS includes robust security settings designed to safeguard users from malicious software.

One of these features is Gatekeeper, which prevents unverified apps from running on your Mac.

When you attempt to open an app downloaded from the internet, especially from an unidentified developer, the system shows this warning and blocks it.

In macOS Catalina and later versions, Apple introduced stricter security protocols that require apps to be notarized by Apple.

Notarization is a process where Apple scans the app for malicious content and confirms that it is from a registered developer.

If the app developer can’t be verified and the app hasn’t been notarized by Apple, macOS cannot verify that the app is free of malware.

Common causes of the “macOS cannot verify” warning

1. Developer Cannot be Verified: The software developer isn’t registered with Apple, so macOS cannot verify the app’s safety.
2. Expired Certificates: The app’s security certificate has expired or is invalid.
3. Downloaded from the Internet: Software downloaded from sources outside the App Store are considered less secure.
4. Strict Security Settings: Your security settings are configured to allow only apps from the Apple Store.

This error message serves as a protective measure to prevent Mac users from inadvertently installing malicious software that could harm their device.

How to open unverified apps securely?

If you frequently install apps from developers outside the App Store but who are registered with Apple, you can modify your settings:

1. Go to System Settings (previously known as System Preferences) and click Security & Privacy.
2. Under Allow apps downloaded from, you will have two options: App Store and App Store and identified developers. Selecting the second option strikes a balance between security and flexibility, allowing you to run software that has been notarized by Apple but isn’t necessarily available in the official App Store.
3. Select App Store and identified developers as it balances between security and flexibility, allowing you to run software that has been notarized by Apple but isn’t necessarily available in the official App Store.

4. Enter your admin credentials if prompted to save your settings.

This setting allows apps from identified developers to run without additional prompts, reducing the frequency of the error message.

The risks of bypassing security warnings

While bypassing these warnings can be convenient, it’s important to understand the risks:

• Potential Malware Attacks: Malicious software can disguise itself as legitimate apps.
• Data Security: Malware can compromise your personal data and system files.

Always ensure that you’re opening apps from an identified developer.

If in doubt, research the app developer and read reviews from other users.
