Could Not Get Code Signature For Running Application

I’ve been an avid runner for years, and I understand the frustration of encountering issues with running applications. One common issue that runners may come across is the error message “could not get code signature for running application.”

When this error occurs, it can be incredibly frustrating and may leave you scratching your head. This issue often arises due to problems with the code signing process, which is essential for ensuring the security and integrity of an application.

Understanding the Code Signature

Every application developed for macOS is required to be code-signed. This process involves adding a digital signature to the application, which allows the operating system to verify the integrity of the code and ensure that it has not been tampered with. Additionally, it provides validation that the code comes from a trusted source.

Possible Causes of the Error

There are several potential causes for the “could not get code signature for running application” error. One common reason is an issue with the developer’s certificate or provisioning profile. If these are not properly set up or have expired, it can lead to code signing failures.

Another possible cause is related to the application’s entitlements. Entitlements specify the capabilities and resources an app is allowed to use and can impact the code signing process. If the entitlements are not configured correctly, it can result in signature-related errors.

Troubleshooting Steps

When faced with the “could not get code signature for running application” error, there are a few steps you can take to troubleshoot the issue. Firstly, ensure that your developer certificate and provisioning profile are valid and properly configured. If needed, renew or recreate these credentials.

Additionally, double-check the entitlements for your application to confirm that they are set up correctly. Pay close attention to any specific entitlements that may be required for the functionality of your app. Reviewing and adjusting these entitlements may help resolve the code signing issue.

If the problem persists, consider cleaning and rebuilding your project. Sometimes, corrupted build settings or cached data can lead to code signing failures. By cleaning the project and rebuilding it from scratch, you may be able to overcome the error.


Encountering the “could not get code signature for running application” error can be frustrating, but with patience and persistence, it can be resolved. Understanding the importance of code signing and being aware of potential causes and troubleshooting steps can empower you to tackle this issue effectively. Remember, reaching out to the developer community or seeking assistance from experienced developers can also provide valuable insights and solutions.
