This means App Store antivirus is less likely to be able to detect all threats, and is also less likely to be able to remove all threats. Even if you grant access to the entire hard drive, many of those files cannot be removed by an App Store app. Ironically, the nature of sandboxing on macOS actually restricts antivirus software, at least if you download it from the Mac App Store.īy default, an antivirus app from the Mac App Store would not be able to gain access to most of the files on your hard drive. This means they can are restricted to doing what they’re meant to do, without being allowed to interfere or access unnecessary critical system files, infrastructure and settings. The Gatekeeper system, meanwhile, will prevent the app from opening without your permission if it hasn’t been digitally signed – this means it’s been approved as a safe app by Apple themselves. This works invisibly in the background, meaning it needs no maintenance or activation and doesn’t slow down your Mac. For example, when you download an app from the internet, your Mac checks it against a list of known malware apps using the built-in XProtect system. Macs do have some stellar built-in tools that protect you right off the bat. Windows PCs make up roughly 90% of the market, making them a much more attractive target to malware makers. The belief that Macs are fairly resilient to malware isn’t just idle fanboy-ism. But is it true that Macs are less vulnerable than Windows PCs? Well, we know that isn’t true – security firms have uncovered malware specifically targeted at Mac computers in 2019. There’s an age-old belief in the tech world that Macs don’t get malware and therefore don’t need antivirus software.
