Good Firewall for El Capitan

[aide199]

Can anyone please recommend a good firewall for use on El Capitan - I used to use Little Snitch but I'm no longer able to use it on El Capitan - There is a nightly build but you have to keep re-activating it after 3 hours.

Thanks in advance

What are you trying to do? The built in OS X Firewall works fine for preventing incoming connections. You must enable it in System Preferences > Security & Privacy first.
Little Snitch is great for blocking outgoing connections, but what is it you are trying to block, exactly?

There is nothing wrong with the firewall that comes wth El Capitan, in my opinion. However, if you want another one, try buying Little Snitch instead of trying to circumvent the registration process. It works with El Capitan.

The nightly build can be activated with the same key as the normal version and after that it does not turn of the filters every three hours. I am using it since the first beta and had no issue yet.
