This really boggles my mind that the firewall is still turned off by default in Mac OS 10,10. Even Apple recommends you to turn it on to keep your system safe, what's the deal with this? https://www.apple.com/osx/what-is/security/ "Turn on a firewall to prevent other machines from accessing services running on your Mac." What makes it so that Apple couldn't ship it with the firewall on? I think it would help more if the people who don't really know what a firewall does has it on without knowing and the people who needs it off for some things knows how to turn it off instead of how it is today were a lot of people walk around not even thinking about it.
