In 2020 malware on the Mac actually decreased, however, as you will see if you read on, Macs are not completely safe from attacks. For more information read: how Apple protects you from malware. This is part of Apple's Gatekeeper software that blocks apps created by malware developers and verifies that apps haven't been tampered with. Apple has all the malware definitions in its XProtect file which sits on your Mac, and everytime you download a new application it checks that none of those definitions are present. In addition Apple has its own built-in anti-malware tool.

If you were to install something from an unknown developer Apple would warn you to check it's authenticity. For example, macOS shouldn't allow the installation of third-party software unless it's from the App Store or identified developers, as per the Security & Privacy settings, that you can access in System Preferences > Security & Privacy > General. Luckily Apple has various measures in place to guard against such threats. For example, the WannaCry/WannaCrypt ransomware that bought the NHS to its knees in May 2017 was only targetting Windows machines and therefore no threat to Macs.
However, before you panic, Mac malware and viruses are very rarely found "in the wild".įrom time to time you will hear of big profile trojans, malware, and ransomware that is targetting the Windows world, very rarely is this a threat to Macs. Despite Apple's best efforts, Mac malware does exist, we describe some cases below.
