How to Turn On a Firewall on a Mac……for free!

I’ve recently had a lot of people come up and ask me what firewall and antivirus they should buy for their Mac Desktop or Macbook laptop. Well you don’t have to buy an antivirus (there is currently no virus out there for the Mac, and no trojans unless you pirate software) and the Mac computers already come with a built-in firewall. You just have to turn it on.

So how do you do it? Here’s how:

Step-By-Step:

1. Click on the Apple Logo on the upper-left corner of your screen.
2. A Menu will pop up. In that menu click on System Preferences.
3. The System Preferences window will open. In that Windows find and click on the Security Icon.
4. The Security Window will open. Check the bottom of the Security Window. If the padlock icon is closed then click on it and enter your password. This will enable you to start the firewall. If the padlock is already unlocked then leave it that way.
5. Click on the Start Button.
6. Close the Security Window. And you’re done!

Cheers!
