![]() To do this, run the following command: sudo spctl -master-enable.It is important that you enable the checks again after you have used the application.Once you have done that, go ahead and run the application.Provide your admin password to complete the execution.Once the Terminal has launched, execute the following command to disable checks: sudo spctl -master-disable Disabling Global Checks.You can do so via Finder > Go > Utilities or just simply searching for it in the Spotlight.To disable Gatekeeper, you first have to open up a Terminal window on your Mac device.Therefore, the easy workaround here is to just disable the feature temporarily and then turn it on again. That is why you receive the said error message. As it turns out, in some cases it treats certain apps unsigned apps that you downloaded as unsafe. As we have mentioned above, the Gatekeeper is a security feature in macOS that essentially checks the apps that you wish to run and protects your system from malware. You will be asked for your admin password, provide that, and press Enter again.Īnother way that you can get rid of the error message is to disable global checks temporarily.Once you have done that, just write sudo xattr -cr in front of the path and then hit Enter.That will automatically paste the path of the application. A neat little trick here would be to just navigate to the directory where the app is located and then dragging and dropping it to the terminal window.Once the terminal window is up, use the following command to run the application: sudo xattr -cr /path/to/application.app Running App from Terminal.From there, locate and open up a Terminal.First of all, open up a Terminal window by going to Finder > Go > Utilities.With that said, follow the below instructions run the app: Doing this for any random app you got off of the internet is not a good idea. You should do this only and only if you trust the application that you wish to run completely. Basically the superuser permissions will override the Gatekeeper feature and thus the application will be allowed to execute. ![]() Method 1: Run the App From a Terminal WindowĪs it turns out, if you run the same application from a terminal window using superuser permissions, it will run without any issues. With that said, let us get into the various methods that’ll help resolve the issue. In such a case, to overcome the problem, what you will have to do is either change your System Preferences, run the application using the xattr command, or disable Gatekeeper for a while altogether. Now, this might be really helpful in most of the cases but there are apps that are trusted and they are detected as unsafe by the Gatekeeper security feature. The app is treated as unsafe and thus you are suggested to delete it. However, in some scenarios, when the app you wish to run is an old and unsigned version, you are thrown the said error message as Gatekeeper does not allow it to run. macOS has a specific security feature that checks the applications that you wish to run and then depending on the code signing, allows the application to be executed. The reason this error message occurs is pretty obvious. When you try to run an application that is either not digitally signed correctly or other software that is developed by the community for different purposes, you might get the “ Application.app is damaged and can’t be opened” error message. However, that is not the case when it comes to Mac systems. For Windows users, they often just get a warning along with an option to run the application anyway. Often times we run applications on our system that are not signed correctly or in some cases, just old.
