What causes can’t be opened because Apple cannot check it for malicious software error?
We all know how Apple is strict about what programs you can use on your device. While iOS devices don’t allow you to sideload apps, the same doesn’t go with your Mac.
But still, Apple wants you to only use the apps that Apple authorizes. Any app that you have downloaded from the Mac App Store is a trusted app by Apple already.
But when you try to install or run apps outside the App Store or any plugins or installer package, the macOS checks the Developer ID signature to verify that the software is from an identified developer.
If it verifies successfully, you won’t see any error. But in case, if macOS fails to verify the software, you will encounter the “cannot be opened because Apple cannot check it for malicious software”.
