First level: Hardening macOS

First level: Hardening macOS

What can I say, there are bad guys out there, you have be secure!
Below is a very short list of things that you can do to make your computer harder to crack, then all the other computers in your town / city.
Remember, security is not a one time thing! You have been vigilant all the time! Back up your data every day, encrypt sensitive data on your Mac! Do not leave your Mac unlocked, at best take it always with you! BE SAFE!

  1. Disable crash reports in Mac OS:
sudo defaults write com.apple.CrashReporter DialogType none
  1. Disable Captive Portal:
sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.captive.control Active -bool false
  1. Secure FileVault when Mac sleeps:
sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.captive.control Active -bool false
  1. Uncheck the option ‘Allow guests to log in to this computer’ - System Preferences > Users & Groups > Guest User and uncheck
  2. Set Require password after sleep to immediately - System Preferences > Security & Privacy > General
  3. Turn on the firewall - Go to System Preferences > Security & Privacy > Firewall
  4. Uncheck Enable Location Services - Go to System Preferences > Security & Privacy > Privacy > Location
  5. Uncheck Share Mac Analytics - Go to System Preferences > Security & Privacy > Privacy > Analytics
  6. Change your DNS servers, add two entries to DNS Servers for 1.1.1.1 and 1.0.0.1 and remove any other server - Go to System Preferences > Network > Advanced > DNS

Reboot and log back in.

This is just a basic list of things that are recommended to do on your Mac!
Enjoy!
