Are you a Mac user and bothered because of the “cannot be opened because the developer cannot be verified” error?

You don’t have to fret anymore because this article explains how to fix this issue.

Keep reading and learn what this error is and what solutions you can implement.


Generally speaking, the Mac App Store is the most secure location from which to download and install applications. A fascinating aspect of the Software Store is that each app is checked before being accepted. And, if there are any problems, Apple removes the app instantly.

Assume that you get an app from the internet or even from the developer rather than the App Store. In that case, your MacOS will still check the Developer ID verification.

Such verification is implemented to make sure that those apps are compatible and secure. Mac users will get the aforementioned error message if the app’s creator isn’t an Apple-approved developer.

To get the software installed on your computer, simply double-click the file called “.setup.” Don’t panic if you see the same problem message.

In order to fix this error, follow the steps in this article. As a result, you can’t proceed with the fix since Mac doesn’t trust the developer.

Besides, struggling with Safari can’t establish a secure connection to the server issue on iOS? If so, here are some effective methods to fix it for you.
