How To Protect Your Privacy On Mac

Follow these easy steps to protect the personal data on your device running macOS or Mac OS X.

1. Easily encrypt your Mac with the built-in FileVault.
Turn FileVault on to make your files are unreadable if someone else gets hold of your computer while powered off or locked.
How: System Preferences > Security & Privacy > FileVault


2. Set a password for your account and disable automatic login.
Remember to require your password after your Mac sleeps and of course, use a strong, lengthy password. Note that Disable automatic login has been removed from macOS Sierra.
How: System Preferences > Security & Privacy > General


3. Update macOS regularly.
Don’t ignore those installation prompts! Remember you can check for updates at any time.
How: Apple icon > About This Mac > Software Update


4. Make sure the firewall is turned on.
Enabling the built-in firewall will block incoming connections. You can also choose to allow only signed software to accept incoming connections under Firewall Options.
How: System Preferences > Security & Privacy > Firewall


5. Enable stealth mode.
Being in stealth mode means your Mac will not respond to connection attempts from the network.
How: System Preferences > Security & Privacy > Firewall > Firewall Options


6. Set the computer to log out after a period of inactivity.
The default for automatic logout is 60 minutes but shorter is better.
How: System Preferences > Security & Privacy > General > Advanced


7. Require an admin password for system-wide changes.
This helps protect against malware doing widespread damage.
