So if you're not that tech savvy then you should definitely set it at the lowest level and have it only allow apps from the App Store.

It just prevents things from getting installed. So Gatekeeper is kind of a gateway system. So there's some level of security with just signing an app. There's been some identification checks and Apple can revoke that. Even if the app is from outside the App Store if it's an assigned app, that means the developer is part of the Apple Developer Program. If there are problems Apple can actually pull it out of the App Store and take away the developer's ability to produce new apps in the App Store or even as assigned developer. It's not a perfect system but it does allow Apple to check for a lot of things including whether it presents a security or privacy vulnerability and just some quality guidelines that Apple has. If an app is in the App Store then it was submitted by an identified developer with a developer account with Apple and Apple reviewed it before they allow it in the App Store. So this is like your first line of defense. Beyond these two options you do actually have the ability to install any software you want as long as you give it permission. You can only allow apps to be installed from the App Store or you can allow apps from the App Store and from identified developers. You can't even actually change them unless you authenticate and then you have two options. Years ago they actually had a little icon there and they called this gatekeeper. If you go to Apple menu, System Preferences and then you go to Security & Privacy and you look under General there's a section here called Allow Apps downloaded from. The first part is called Gatekeeper except you won't find something called Gatekeeper anywhere on your Mac anymore. Now this protection software is in three parts. They just quietly built it into the operating system and it protects you. They don't want to talk about how there are trojans out there for the Mac. They don't talk about this much because, of course, they don't want to publicize that part of it. For years now Apple has include anti-malware software built into the operating system. The good news is that the best software for the job is already on your Mac. Now you want to prevent that malware from getting on your Mac. Sometimes the malware comes along for the ride when you install the software.

Sometimes that software itself is malware. These are pieces of software that you install yourself because you've been tricked into downloading software from a site you shouldn't trust. A virus is just one type of malware and it's rare today. You're looking for anti-malware software. You're not really looking for anti-virus software. A lot of times people say I just don't feel comfortable not running anti-virus software or my company says I have to have it on my computer. So I often get asked what's the best anti-virus software for the Mac. Find out how you can become a part of it at /patreon. MacMost is brought to you by a community of more than 350 supporters.
