Firewall is a built-in software on your computer that is designed to prevent malware, viruses, and hackers to get into your computer and it is highly recommended that the firewall is always turned on.
On the other hand, Firewall can also be a barrier to some legitimate network, messaging application or websites that you would like to use and can prevent you from using. Since it may automatically detect that it is not safe depending on the settings and configuration on how you set it up.
So you may want to adjust your firewall settings on just how you want it to secure your computer, or you must manually add these networks on your list to bypass the security protocol of Firewall. It can be tedious at times especially if you are in a hurry or having to add a network every now and then, this process can be eliminated by simply turning off your firewall.
But remember that by doing so, you are removing an added layer of protection on your computer and may make it vulnerable to malware, viruses, and hackers.
If you want to enable your firewall and move freely on your computer to eliminate the tedious process, you can use the iMyMac PowerMyMac in just one click, it will perform a deep scan on your computer that will eliminate the unwanted files.
