This broke a lot of long-standing system tweaks, which is why some people look for ways to disable system identity protection. Whereas previously a user could open the Terminal and change anything about the system with enough knowledge, most of the system is completely off limits now.

System Identity Protection, called SIP for short by some and “rootless” by others, makes it basically impossible for anything but a macOS update bundle to change core aspects of the operating system. The modern web doesn’t require Java or Flash that much anymore, so if you can avoid running them altogether that’s probably for the best. Enable them only on sites you trust, and only when necessary. You can disable these plugins in other browsers as well, and it’s probably a good idea to disable Flash and Java in basically all circumstances. Safari, the default web browser on macOS, disables both of them by default, running the plugins only when you specifically re-enable them.

On the modern web Java and Flash are both largely avoidable. It’s essential that you keep these plugins up-to-date.

Two of the most common vectors for Mac malware are Java and Flash, browser plugins that powered the early web but are increasingly becoming obsolete. Just make sure you’re only running applications you know for a fact that you can trust.

Seriously, though: installing pirated Mac apps from sketchy sites is the most common way to end up with malware, followed closely by clicking ads suggesting something like “Your Adobe Flash software is out of date.” If you install software from untrustworthy sites, no anti-malware software can help you, and there’s no telling what kind of infection you might end up with. It’s called “piracy,” and I’m sure an upstanding citizen such as yourself has never heard of it. If you know where you look, you can find any Mac application for free. It’s annoying, sure, but it’s an important way to keep your Mac safe. If you see a notification insisting that you install an update, do it. You can even enable automatic updates in the background if you don’t want to deal with managing everything on your own.Īs for applications that you didn’t get from the Mac App Store, that’s up to you. And macOS is very good about notifying you about these updates, with banners that are impossible to miss and a number in the menu bar. Happily, the Mac App Store makes managing updates pretty easy, by putting system updates and updates for a lot of your applications all in one place.

Vulnerabilities in any application is a potential problem. Your browser is a huge potential vector for infection, so make sure that is up to date. Updates for your applications are also essential.
