But Apple will change those "warnings" into straight-up lies, and fail to mention the user can override them, and hide those overrides in non-discoverable places:
Whenever I try to open an unverified app, this popup comes up saying "[AppName] Not Opened" "Apple could not verify [AppName] is free of malware that may harm your Mac or compromise your privacy." Then there's only two options to either press "Done" or "Move to Trash." - https://old.reddit.com/r/mac/comments/1ekv55h/cant_right_cli...
This also implies that Apple does verify that app store apps are free from malware, when that's not the case. It only verifies that they are from a developer who paid the fee and whose apps pass Apple's automated screens.
