Do I need MAC cleaner??

Hi,

Your Mac does not require any anti virus or so called “cleaning apps” in fact they can slow down your Mac or completely ruin that install of macOS.

Avoid opening or downloading items from email messages and websites unless you are certain that they come from a legitimate, trusted source. If you’re uncertain about the source, delete the item.

Gatekeeper is a new feature in Mac OS X Lion or later that builds on OS X's existing malware checks to help protect your Mac from malware and misbehaving apps downloaded from the Internet.

Hope that helps

you don't need it-you don't want it, CarolRealtor. Trust us on this one. We're not kidding. That Causes way, way more problems than it solves. Stay far far away from it, and any other thing that claims to "clean your Mac of junk" . Maybe you might need Malware anti-Bytes, but that's a big maybe.

Well, yes, because you're not behind your own router at home. On any public Internet connection, you should have your firewall on.

At home, the built-in firewall is only wasting system resources looking for nothing.

shouldn't firewall be on if you're using a public wifi?.

If you have sharing services enabled in the Sharing System Preferences, the Application Firewall may be useful on Public WiFi. Otherwise, your Mac isn't listening (i.e. not responding) to any random request.

Turning on the Firewall may be simpler than disabling all of the sharing services while on a Public connection.

No,you don't need either

you don't need anything except your apple firewall turned on in the (System preference > security & privacy) and maybe a safari adBlock extension.

Anything that claims it will clean, protect or make your Mac run faster are lying to you.

They should all be avoid \ed because they are dangerous to have them installed on your Mac.

And if your Mac is attached to a firewall enabled router (and virtually all of them have one), you don't even need that on. There's nothing for the OS firewall to do when it's already behind one.
