Best Firewall For Mac
Although the default setting for your Mac’s firewall should be adequate for most people, you may want to configure your firewall to block additional Internet features for added security. For example, most people will likely need to access e-mail and web pages, but if you never transfer files by using FTP (short for File Transfer Protocol), you can safely block this service.
Don’t configure your firewall unless you’re sure that you know what you’re doing. Otherwise, you may weaken the firewall or lock programs from accessing the Internet and not know how to repair those problems.

Mac Os Firewall Settings
Beginning with Mac OS X 10.7 Lion, your Mac’s security was enhanced with two features:
Advanced Space Layout Randomization (ASLR): Makes your applications more resistant to malicious attacks
Sandboxing: Limits the types of operations an application can do, thereby making it difficult for a threat to take advantage of an application and, consequently, affect the whole operating system. Think of it as strengthening a potential weak link.
