Check Fix ‘Can’t be opened because it is from an unidentified developer’ Issue on Mac
By default, macOS allows users to only install apps approved by registered Apple developers who have verified their apps for use on the Mac. If an app developer doesn’t register with Apple or skips the verification process, you’ll get a “Cannot open because the developer cannot be verified” error when trying to install the app. While Macs are less likely to get viruses than Windows PCs, they can still get infected. Apple has a developer ID system and app review process to reduce how often users are exposed to malware on macOS. Developers must register with Apple and submit their apps for review. When an app is free from malicious code like malware, the app is signed and approved.
If you try to install an app from a developer that is not registered with Apple, you will receive an error message. If a registered developer releases an app that Apple hasn’t reviewed, the same thing happens. If an app was published before the registration and verification processes began, it would throw the same error. The app may be safe, but there’s no way for Apple to know one way or the other if they haven’t been able to verify it. By default, it does not allow you to install apps from unidentified developers. However, along with the many malicious apps that fall under the category of apps from unidentified developers, there are also many high-quality ones.
