How to Fix ‘Cannot Be Opened Because the Developer Cannot be Verified’ Error on Mac
If you’re a Mac user, you’ve likely come across the “Cannot Be Opened Because the Developer Cannot be Verified” error at some point. This error occurs when you try to open an app that isn’t from the App Store or a trusted developer. While this error can be frustrating, it’s actually there for your protection – it’s a security feature designed to prevent you from opening potentially harmful or malicious apps.
But what do you do when you need to open an app that the Mac won’t let you open? Fortunately, there are a few steps you can take to fix this error and get your app up and running.
Method 1: Control-Click the app and select “Open”
The quickest and easiest way to bypass the “Cannot Be Opened Because the Developer Cannot be Verified” error is to simply control-click (or right-click) on the app icon and select “Open” from the context menu. This will open a dialog box asking if you’re sure you want to open the app, since it’s from an unidentified developer. Click “Open” to proceed, and the app should open as normal.
Method 2: Adjust your security settings
If you don’t want to have to control-click every time you want to open an app from an unidentified developer, you can adjust your Mac’s security settings to allow you to open these apps without encountering the “Cannot Be Opened Because the Developer Cannot be Verified” error.
To do this, go to System Preferences > Security & Privacy. In the General tab, you should see a message saying “App downloaded from ____ was blocked from opening because it is not from an identified developer.” Click the “Open Anyway” button next to this message, and the app should open without issue.
Method 3: Disable Gatekeeper altogether
If you’re comfortable with the risks of opening apps from unidentified developers and you don’t want to adjust your security settings every time you encounter the “Cannot Be Opened Because the Developer Cannot be Verified” error, you can choose to disable Gatekeeper altogether.
To do this, open Terminal (you can find this in Spotlight by typing “Terminal”) and enter the following command:
sudo spctl –master-disable
You’ll need to enter your admin password to complete this step. Once you’ve done this, you should be able to open any app without encountering the “Cannot Be Opened Because the Developer Cannot be Verified” error.
However, be aware that disabling Gatekeeper entirely can leave your Mac vulnerable to malware and other security threats. It’s not recommended unless you have a specific reason for doing so and understand the risks involved.
In conclusion, if you encounter the “Cannot Be Opened Because the Developer Cannot be Verified” error on your Mac, don’t panic. There are several easy fixes you can try to get your app up and running. Whether you choose to adjust your security settings, disable Gatekeeper altogether, or simply control-click to open the app, you should be able to bypass the error and get back to using your Mac as normal.
