Are you worried about the security of your Mac? You're not alone. Apple recently released a solution to address the issue, but some machines may still be vulnerable. To protect their customers, Apple doesn't disclose, discuss, or confirm security issues until an investigation has been conducted and patches or versions are available. The most recent versions can be found on Apple's security updates page.
Apple's security documents refer to vulnerabilities using CVE-ID when possible. On the software side, MacOS includes its own built-in antivirus software called XProtect. This program detects and blocks any known malware. Apple monitors for new malware infections and updates XProtect regularly. XProtect will check for malware when an application is launched for the first time and if it has been modified.
If XProtect detects malware, it will block the software and remove it. Apple ensures that security updates are released on Macs regularly, so it's important to keep your Mac software up to date. You'll still have to restart your Mac to install a normal software update; however, Apple can send some security updates to your Mac and install them as background updates without requiring you to restart. Fortunately, there are several free and very secure third-party DNS options available to all Mac users. For that reason, it's worth changing your Mac's DNS settings to one of those services. This will help protect your Mac from malicious attacks and keep your data safe.
