It’s not that great of a solution, though. I dunno if anyone remembers but, when Gatekeeper (the interface to do this) first was added to MacOS, it was in response to a malware “virus scanner” that was out called MacKeeper. It was advertised as a malware scanner/Mac maintenance tool but it was just an ad platform that would inject all kinds of crap into your browser and run all kinds of keyloggers and things in the background.

As soon as Gatekeeper was released, the MacKeeper website made a specific page that had step-by-step instructions for how to disable Gatekeeper and it would prompt you to visit the page if MacKeeper ever made it onto your system. If you ever re-enabled it, it would prompt you to disable again and show you the instructions.

It’s an endless cat and mouse game. The only way this works is if they put it in as a multi-step terminal process. Novice users will not fuck with the terminal unless they know what they’re doing and are comfortable with the consequences.
