Additionally, macOS system files and user data are stored on separate disk volumes which makes it more challenging for malware to cause problems with the system. Since macOS 10.15 (Catalina), apps require explicit permission to access user files and other sensitive information (e.g., camera, microphone, logs). This does not protect you from malware but limits what it can do. Sandboxed apps (e.g., downloaded from the Apple App Store) run in an isolated context where they cannot access areas outside of it and thus cause damage. For example, Sandboxing isolates apps from critical system components, user data, and other apps. MacOS includes other features which secure and harden the system. ![]() System and security updates are installed automatically using the macOS update process. These features are essentially invisible to the user, other than configuration options and alerts. ![]() Moreover, Apple Mac security needs to be considered in the wider context of other types of attacks.Īpple ships some anti-malware capabilities within macOS: Gatekeeper, which warns when apps without a digital signature (i.e., not certified by Apple) are run, and XProtect Remediator, which checks files against known-malware signatures and remediates infections if malware makes its way onto the Mac. ![]() Whilst it is certainly true that the population of macOS malware is very tiny compared to that for Windows and Android, there have still been many instances of macOS malware getting into the wild. It is an often-heard view that macOS computers don’t need antivirus protection.
