Keep your Mac secure
Expert insight on all of the steps you can take to make your Mac impenetrable in macOS Catalina
Your Mac holds your world. Everything from work files, login details, music, photos, videos, to a whole array of other things you want to protect. You may not have considered your Mac’s security in too much depth as of yet, however, it’s important you know how to keep it safe.
For example, your Mac has a built-in firewall that is enabled by default. This is useful in preventing anyone from attempting to break into your Mac. Likewise, you can find FileVault in your Security & Privacy System Preferences. When turned on, this encrypts the contents of your Mac automatically, and you’ll need a recovery key or password to access your data. Be warned: there is no ‘forgot my password’ option.
