What Process Puts Up the "Developer Cannot Be Verified" Panel on macOS?

Understanding the "Developer Cannot Be Verified" Panel

The "Developer Cannot Be Verified" panel on macOS is a security feature designed to protect users from potentially malicious software. This panel appears when a user attempts to launch an application that has not been verified by Apple as a trusted developer. The panel displays a warning message, stating that the developer cannot be verified, and provides options to either cancel or open the application anyway.

What Triggers the "Developer Cannot Be Verified" Panel?

The "Developer Cannot Be Verified" panel is triggered by a process called Gatekeeper, which is a security feature built into macOS. Gatekeeper is responsible for checking the identity of the developer who created an application and verifying that it has been signed with a valid digital certificate issued by Apple. If the application has not been signed or has been signed with a certificate that is not recognized by Apple, Gatekeeper will display the "Developer Cannot Be Verified" panel.

How Gatekeeper Works

Gatekeeper works by checking the following:

Developer Identity: Gatekeeper checks the identity of the developer who created the application to ensure that it matches the identity provided in the application's digital certificate.
Digital Certificate: Gatekeeper verifies that the application has been signed with a valid digital certificate issued by Apple.
Code Signing: Gatekeeper checks that the application's code has been signed with a valid digital signature.

What Processes Can Trigger the "Developer Cannot Be Verified" Panel?

Several processes can trigger the "Developer Cannot Be Verified" panel, including:

Launching an Unverified Application: If a user attempts to launch an application that has not been verified by Apple, Gatekeeper will display the "Developer Cannot Be Verified" panel.
Installing an Unverified Application: If a user attempts to install an application that has not been verified by Apple, Gatekeeper will display the "Developer Cannot Be Verified" panel.
Running a Script or Command: If a user attempts to run a script or command that has not been verified by Apple, Gatekeeper will display the "Developer Cannot Be Verified" panel.

Troubleshooting the "Developer Cannot Be Verified" Panel

If the "Developer Cannot Be Verified" panel is displaying a spinning beach ball or is hung, there are several troubleshooting steps that can be taken:

Restart Your Mac: Restarting your Mac can sometimes resolve the issue.
Check for Software Updates: Ensure that your Mac is running the latest version of macOS.
Disable Gatekeeper: Temporarily disabling Gatekeeper can allow you to launch the application, but be aware that this may compromise your security.
Contact the Developer: If the issue persists, contact the developer of the application to report the issue.

Conclusion

The "Developer Cannot Be Verified" panel on macOS is a security feature designed to protect users from potentially malicious software. Gatekeeper is the process responsible for triggering this panel, and several processes can trigger it, including launching an unverified application, installing an unverified application, and running a script or command. Troubleshooting the "Developer Cannot Be Verified" panel can be done by restarting your Mac, checking for software updates, disabling Gatekeeper, and contacting the developer.
