Troubleshoot Verification Errors on Your Mac – Easy Solutions Inside

By default, macOS allows users to install only approved apps from developers registered with Apple that have verified their apps for use on Macs. When the developer of an app doesn’t register with Apple or skips the verification process, you’ll see a “Cannot Be Opened Because the Developer Cannot be Verified” error when you try to install the app.

When this error occurs, the app won’t install or open and you’ll typically see an error message like:

• “(App name) can’t be opened because it is from an unidentified developer. Your security preferences allow installation of only apps from the App Store and identified developers.”
• “(App name) cannot be opened because the developer cannot be verified.”
• “(App name) can’t be opened because Apple cannot check it for malicious software.”

What Is the Cause of the ‘Cannot Be Opened Because the Developer Cannot Be Verified’ Error on Mac?

WhileMacs are less likely to get viruses than Windows PCs, they can still get infected. Apple has a developer ID system and an app review process to reduce the frequency of users exposed to malware on macOS.

Developers must register with Apple, and they have to submit their apps for review. If an app is free of malicious code like malware, the app is signed and approved.

When you try to install an app from a developer who hasn’t registered with Apple, you’ll see an error message. If a registered developer releases an app that Apple hasn’t reviewed, the same thing happens.

If an app were released before the registration and review processes started, it would trigger the same error. The app may be safe, but there’s no way for Apple to know one way or the other if they haven’t been able to review it.

How Do You Fix ‘App Can’t Be Opened Because It Is From an Unidentified Developer?’

To fix the error where you can’t open an unapproved app on your Mac, you have a few options.

1. Look for a newer version of the app . Check the Mac App Store and see if the app is available there. If you downloaded it from a different source, you might have an old version of the app. The developer may have released a signed and verified version in the App Store since then.
2. Look for an alternate version of the app. Check the Mac App Store to see if an app from an approved developer does the same thing. If you can find an app that performs the same functions, and it’s from an approved developer who has gone through the verification process, consider trying that app.
3. Override your security settings. If you’re sure you trust the app developer, you can allow the app to install and open. From Finder,Control+Click the app > clickOpen .
   The app should be saved as an exception in your security settings, allowing you to open it in the future.
4. Bypass the block in your Privacy & Security settings. If the previous method didn’t work, you can do it manually fromSystem Settings >Privacy & Security > look for the app > clickOpen Anyway.
   
   In older versions of macOS, openSystem Preferences >Security & Privacy >General > click thelock icon > enter your username and password >Unlock >App Store and Identified Developers . You may see the option to clickAnywhere >Allow From Anywhere .
5. Download the app through Safari . If the above process didn’t work, make sure you downloaded the app using Safari. Delete the app > restart your Mac > download the app using Safari > and try to run the app. When you get the error message, perform the Privacy & Security fix outlined in the previous step.
   There’s an issue where downloading apps through other browsers, like Chrome and Edge, will cause a problem when trying to install unsigned apps.
