How to Protect Your Privacy on Mac
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 > Change Password. We suggest selecting “require password immediately” and “disable automatic login”.
13. Install a privacy-focused browser like DuckDuckGo.
DuckDuckGo’s Private browser has built-in tracker network blocking, smarter
encryption, and, of course, private search, all designed to operate seamlessly
together while you search and browse the web.
How: Get the extension for popular browsers from https://duckduckgo.com/app
