Are you having some trouble while installing an app on macOS? Are you stuck with the “Cannot be opened because the developer cannot be verified” error on Mac? Don’t worry! You can easily troubleshoot this issue by making a few quick changes in your device’s settings.
Well, as a security measure macOS allows you to download and install applications from trusted sources. So, if the developer of a certain app is not registered with Apple, you may encounter this error on your Mac. In a way, Apple prevents you to download an app from an unreliable source and throws this error on the screen thereby hindering you to install the app on your device. If the developer is not verified with Apple, you may see the “App cannot be opened because the developer cannot be verified” error. This app blocking measure by Apple protects your Mac from malware and other threats that may sabotage your data or privacy.
But if you still want to proceed and install the app anyway on your Mac, here are a few solutions that you can try to bypass the error message on macOS.
Let’s get started.
