I recently linked two articles about how to set up your Windows and iOS devices for privacy. In this article, I will show you settings that you can use to configure your Mac for privacy.
Require password immediately after sleep or screen saver.
In System Preferences, open Privacy and click on General. Then click on the drop-down menu and select 'immediately'.
Requiring the password immediately protects your data if you leave your Mac unattended.
2. Turn on your firewall.
In Security & Privacy, click on Firewall and press 'Turn On Firewall'.
A firewall protects your computer from hacking and malware/spyware attacks.
3. Limit apps' access to personal data.
In Security & Privacy, select Privacy, then select Location Services (or other data type) and deny access to apps that don't need it, or disable these services entirely if not needed.
Apps may use this data to track you or steal your files. Even if their intent is not malicious, having your data in more places than it needs to be increases your risk of a data leak.
4. Turn on FileVault.
In Security & Privacy, select FileVault and click 'Turn On'.
FileVault protects your files if your Mac is stolen and the hacker manages to access the hard drive. They will then have to log in to the computer and will be unable to hack the disk.
5. Enable Touch ID.
Open Touch ID, then add a fingerprint.
Biometric identification like fingerprints are more secure than passwords, because hackers can't guess your fingerprint. If they don't have your finger, they can't log in to your Mac.
6. Keep your Mac up to date.
Open System Preferences, then click Software Update.
Software updates often contain security fixes. Up-to-date software is harder to hack than old software. Updating your computer will protect you from hacking and malware.
