Part 1. What Causes “Cannot be opened because Apple cannot check it for malicious software” Error
If you are seeing the “can’t be opened because Apple cannot check it for malicious software.” message for the first time, you will probably be wondering how it came up on your Mac all of a sudden.
In the new versions of macOS, Apple wants you to only use the apps that are authorized by Apple itself. All apps downloaded from the Mac App Store fall into the authorized category. However, when you install Mac apps, plug-ins, and installer packages from outside the App Store, macOS checks the Developer ID signature to verify that the software is from an identified developer and that it has not been altered.
If you see this warning, it means that the app was not notarized, your Mac throws the message that reads “cannot be opened because Apple cannot check it for malicious software”.
