Diagnosis: Modern macOS, like Mojave and Big Sur, includes a technology called Gatekeeper, which is built to help you safely open apps on your Mac. For sure Apple App Store is the best place to get software applications, but in many cases, you'll need to download and install apps out of the store. To distribute apps without App Store, it requires the developer to have valid Apple Developer ID and get their apps notarized. Otherwise, it has large chance that they'll get the following error: 'XXX can't be opened because Apple cannot check it for malicious software.'
