Your Mac’s robust security features are designed to protect your system from potential threats, including malware. However, encountering the “macOS cannot verify that this app is free from malware” error can be frustrating, especially when trying to install a legitimate application. This error is a sign that your Mac’s built-in security measures are working diligently to safeguard your system. In this article, we will explore the causes of this error and provide you with effective solutions to resolve it, ensuring a secure and seamless experience on your Mac.
What Causes the “macOS cannot verify that this app is free from malware” Error?
The “macOS cannot verify that this app is not malware” error typically arises when attempting to open an application that lacks proper notarization or developer signatures. macOS employs a security feature known as Gatekeeper to assess the legitimacy of the applications you wish to install. It verifies whether apps are digitally signed by developers, ensuring they are safe for use on Apple devices. Several factors can lead to this error:
- Unsigned or Unnotarized Apps: Apps that lack digital signatures or haven’t undergone the notarization process with Apple will trigger Gatekeeper to block their execution to prevent potential malware threats.
- Developer Certificate Issues: If a developer’s certificate has expired or been revoked, Gatekeeper may deem the app unsafe for use.
- Apps Downloaded from Untrusted Sources: Downloading apps from untrustworthy or unofficial websites can trigger this error, as it warns against potential threats.
- Outdated macOS Version: Running a newer, more security-conscious app on an outdated macOS version may also result in this error.
Best Ways to Fix “macOS cannot verify that this app is free from malware” Error:
- Download Apps from Authentic Sources: Ensure that you only download apps from verified sources, such as the official website or the App Store. Avoid installing apps from untrustworthy websites to prevent the “can’t be opened because Apple cannot check it for malicious software” error.
- Adjust Gatekeeper Settings: You can modify Gatekeeper settings to allow apps from sources other than the App Store. Open the Settings app, navigate to Privacy & Security, and select “App Store and other identified developers” to enable downloads from trusted sources.
- Use Control-Click Method: This method whitelists specific apps, allowing them to run without security warnings. Locate the troubled app in the Applications folder, press Control, and click on the app icon. Select “Open” to run the application without encountering the error.
- Disable macOS Gatekeeper (Caution Required): You can temporarily disable Gatekeeper by using Terminal commands. This option should only be considered if you are certain about the app’s trustworthiness. Use the ‘sudo spctl –master-disable’ command and select “Anywhere” under “Allow applications downloaded from” in Privacy & Security settings.
- Redownload and Install the App: If the app’s signature has changed or it’s corrupted, deleting and reinstalling it can resolve the error.
- Contact Developer Support: Reach out to the app’s support team, especially if it is from a reputable developer. They may provide guidance on using the application safely and addressing the “macOS cannot verify that this app is free from malware” error.
Conclusion: Encountering the “macOS cannot verify that this app is free from malware” error may seem daunting, but with the right knowledge and steps, you can overcome it. By following the solutions provided in this article, you can ensure a secure and hassle-free experience while using your Mac.
