Cannot Be Opened Because The Developer Cannot Be Verified.

Have you ever encountered the warning message “Cannot be opened because the developer cannot be verified” while trying to launch an app? This alert is a security feature in macOS that prevents users from downloading and running apps from unknown developers. In this article, we will look at what this message means and how to solve the issue.

Understanding “Cannot Be Opened Because The Developer Cannot Be Verified”

This security feature in macOS is known as “Gatekeeper” and it is designed to protect users from downloading and running apps from untrusted sources. When a user attempts to open an application, Gatekeeper checks to see if the application is from a verified source. If the application is not verified, Gatekeeper will display a warning message that reads “Cannot be opened because the developer cannot be verified”.

Gatekeeper is enabled by default on all Mac computers and can be customized in the Security & Privacy settings. In this settings menu, users can choose to allow apps from the App Store and/or identified developers, or allow apps from any source.

Solving the Issue

If you receive the warning message “Cannot be opened because the developer cannot be verified”, the first step is to make sure you are downloading the application from a trusted source. If the application is from the App Store or a verified source, you can adjust your Gatekeeper settings to allow apps from that source.

Another solution is to manually override the Gatekeeper settings. To do this, right-click on the application and select “Open”. This will open a warning window that asks if you are sure you want to open the application. Select “Open” in this window and the application should open without any further warnings.

The last option is to disable Gatekeeper entirely. This is not recommended as it leaves your Mac vulnerable to malicious applications. To disable Gatekeeper, open the Terminal application and type in the command “sudo spctl –master-disable”. This will disable Gatekeeper and allow you to open applications from any source.

The warning message “Cannot be opened because the developer cannot be verified” is a security feature in macOS that is designed to protect users from malicious applications. The best way to solve this issue is to make sure you are downloading the application from a trusted source and adjust your Gatekeeper settings accordingly. If you still receive the warning message after adjusting the settings, you can manually override the Gatekeeper settings or disable Gatekeeper entirely.
