However, if you are sure that the application you are trying to open is completely safe, then there is a way to bypass this security feature.

Why MacOS Doesn’t Open Unverified Apps?

Apple is serious about protecting the privacy of their user’s data, therefore, in your Mac you have an in-built security feature, known as the Apple’s Gatekeeper. This security feature is provided as an extra layer of protection on your Mac, so that users are unable to open apps which are developed by unverified developers.

Whenever you try to open an app on your Mac the first thing Gatekeeper does is to verify the developer of the app. If Mac recognizes that developer as a safe developer, then it allows the app to run on your computer, otherwise, it blocks that app and you are unable to open it. Although most of the time the Apple Gatekeeper is right in its decision, sometimes it may give false warnings and in such cases you have the option to bypass the Gatekeeper.




What are Risks of Opening an App that Cannot Verify?

Apple wants the app developers to submit their apps to Apple for notarization, so that they can verify the safety and stability of that app on macOS. Apple performs a thorough inspection of the components of an app before allowing it on macOS. This system has been created by Apple to ensure that its users are protected from malware and any other kind of malicious codes.

If you decide to bypass this security feature on your macOS, then expose your Mac to many apps that may be dangerous for the safety and privacy of your data. Therefore, when you see the message that ‘macOS cannot verify this app is free from malware’, then you should try to bypass this security feature only when you are completely sure about the authenticity of the app you are trying to open on your Mac.

For your convenience, we are sharing two solutions for this problem. One solution should be used when you have to install only one app and the other solution is for users who want to permanently bypass this security feature. This option has been deliberately offered so that you have the choice of being more responsible while bypassing this protection layer on your macOS.

How to Check Authenticity of an App?

Now that you have decided to bypass the Apple Gatekeeper feature on your macOS it’s advised to check the authenticity of the app you want to open on your Mac without the permission of your OS. Performing this manual verification is extremely important as your computer data’s future safety is dependent upon this verification.

  • Check Resources: Check the source from where you got your app. Whether it’s a website or some other data source, that source should be reliable and tested. Do not try to open an app that you downloaded or got from a source that is new and unverified.
  • History of Developer: You must check the track record of the developer of the app you want to open on your macOS. Developer’s history must be clean and they must have a reputation for developing genuine, safe and authentic applications. Go back and check their history as far back as you can.
  • App is Trusted: Make sure that the app you want to open is a popular app, which has been tried by many users before you. Installing any newly developed app can be risky, it may happen that the developer is good, but the app is unstable and has not been thoroughly tested for regular use.
  • Check Reviews: If the app you are going to open on your macOS has been tried by many users, then it must be reviewed by them as well. You must study those reviews to find out if that app is worth taking the risk. Check the issues that other users face after they use the app on their Mac.

Although there is no sure-shot way of determining the security and stability of an app, by following the above mentioned suggestions you can save yourself from installing many malicious applications on your macOS.
