One of the most common issues encountered by Mac users is receiving an error message that says: “Cannot be opened because the developer cannot be verified.” This problem usually occurs when you try to run an app that hasn’t been signed or verified by Apple. In some cases, it’s a security measure designed to prevent unauthorized software from running on your computer.
However, there are times when you know that the application is safe and legitimate, but it still won’t open due to this error. Thankfully, there are solutions available to recover this issue. One way is to right-click on the application icon and select “Open” from the context menu. This will bypass the security feature and allow you to run the app.
Another solution is to change your security settings temporarily. Go to System Preferences > Security & Privacy > General and click on “Open Anyway” next to the message that says “cannot be opened because it was not downloaded from the App Store.” Selecting this option will override your settings for this particular app only and allow it to run without any issues.
Step 1: Check System Preferences
The “cannot be opened because the developer cannot be verified” error on Mac can be frustrating. Especially when it affects your ability to play videos. However, one of the first steps you should take in fixing this issue is to check your system preferences. This is because the error message typically appears when you try to open an app or file. This error message is typically displayed when you try to open an app or file from an unidentified developer.
To check your system preferences, go to the Apple menu and select System Preferences. From there, navigate to Security & Privacy and click on the General tab. Here, you’ll see a message that says “App downloaded from: [name of developer].” If the app or file you’re trying to open isn’t listed as being from a trusted source, click on the lock icon in the bottom left corner and enter your administrator password.
Once you’ve unlocked these settings, change your Allow apps downloaded from setting to either App Store or App Store and identified developers. This will allow you to open files from sources other than just those that are verified by Apple. By following these steps, you should be able to fix this common error and continue enjoying videos on your Mac without any issues!
Step 2: Disable Gatekeeper
For Mac users, Gatekeeper is a security feature that prevents apps from being installed on the system. It prevents apps from being installed if the app was not downloaded from the Mac App Store or an identified developer. However, this feature can sometimes cause errors when trying to install certain apps. To disable Gatekeeper and fix the “cannot be opened because the developer cannot be verified” error on a Mac, follow these steps:
Firstly, click on “System Preferences” in your Dock and select “Security & Privacy.” Next, click on the lock icon in the bottom left corner of the window to allow changes. You will then need to enter your admin name and password. After unlocking, select “Anywhere” under “Allow apps downloaded from:” This will allow any app to be installed without verification.
It’s important to note that disabling Gatekeeper can increase security risks. It allows any app to be installed without verifying its source. Always ensure you trust the source of any app before installing it on your system.

If you are a Mac user, it is not uncommon to encounter the error message “cannot be opened because the developer cannot be verified” when trying to open an app. This issue can occur when you download and try to install an application from a source that is not recognized by your Mac’s security settings. Fortunately, there is a way to fix this error by allowing apps from anywhere on your device.
To allow apps from anywhere on your Mac, you need to access the Security & Privacy settings. Go to System Preferences and click on Security & Privacy. Next, select the General tab and click on the lock icon in the bottom left corner of the window.

It is important to note that allowing apps from anywhere can put your data at risk since it bypasses Apple’s security checks. Therefore, it is recommended that you only use this setting if you trust where you are downloading applications from. Additionally, remember to switch back to stricter security settings once you have installed any needed applications outside of Apple’s App Store or trusted developers.
Step 4: Download from a Trusted Source
