5 Update Your Software Regularly
Apple regularly issues new versions of macOS that contain critical security updates. These updates patch vulnerabilities, which keeps your computer safe. It goes without saying that we strongly recommend you keep up and update your Mac computer on the regular.
Take the recent discovery of hardware-level security vulnerabilities like Spectre and Meltdown. Apple has since released macOS updates that mitigate the risks involved with these — but you’ll only be protected if you actually download and use the latest software on your Mac.
