Guide: 3 Built-In macOS Security Settings for Mac Users
A recent report from Tom’s Guide highlights three built-in macOS settings designed to strengthen device and data security, particularly for users who travel or connect to public Wi-Fi. The author recommends enabling the Firewall and Stealth Mode under Network settings to block unwanted incoming connections, and activating FileVault in Privacy & Security to encrypt the Mac's SSD against physical theft. For heightened protection, users can also turn on Lockdown Mode or disable Safari's automatic file-opening feature. However, the source notes that Firewall may occasionally cause software connectivity issues, while Lockdown Mode introduces significant trade-offs by restricting unknown FaceTime calls, message attachments, USB connections, and certain web tools like Google Sheets.
