Keep your Mac secure by following these steps.
Check your privacy settings
Make sure that your Mac settings are set up properly to keep your data safe. Manage the information your Mac makes available across the internet or on a network by going to Apple menu > System Preferences > Security & Privacy > Privacy. From there, you can choose which information to share and with whom. For example, you can specify which apps are allowed to see personal information, such as your location, contacts, photos, or music.
Take advantage of the firewall
A firewall protects your Mac from unwanted contact initiated by other computers on a network or the internet. It protects your computer by allowing only authorized services and apps to communicate with your Mac, so be sure to enable macOS’s built-in firewall.
To do so, just go to Apple menu > System Preferences > Security & Privacy > Privacy Then, click Firewall. If the padlock icon at the bottom left is locked, click it and key in your username and password. Enable the firewall by clicking Turn On Firewall.
To modify Firewall settings, click on Firewall Options… just below the “Turn Off Firewall” button. You will find a list of services and apps that are allowed to receive inbound connections. If you want to add an app or service to the list, just click the “+” button below the list itself. However, we recommend keeping this list as short as possible, as the apps listed can be exploited by cybercriminals.
Another useful feature to enable is stealth mode. This option will make your Mac more difficult to find, thus keeping hackers and malware at bay. For instance, if you are in a coffee shop and connected to its unsecured Wi-Fi, enabling stealth mode will make your Mac invisible on that public network. To turn on this feature, just tick the box next to “Enable stealth mode” in Firewall Options. A dialog box will pop up, and you can click on the “Enable Stealth Mode” button.
Ensure that your confidential data remains private by performing minor tweaks on your Mac’s system settings. It takes only a few minutes to ensure lasting online protection. If setting up a firewall or firmware password sounds a little too advanced for you, or if you need to set up more advanced defenses, don’t hesitate to get in touch with our experts.
