Should my Firewall always be on when using my Mac desktop?

The Safe Mac » Do I need a firewall?

This link may give you the information you require. Because your router is a public one you should also check with the router providers.

Hi. Welcome. The Firewall it self is not really nessasary. There isnt much that can break the OS of your computer but to avoid people messing around with your files you could make sure you have your file sharing and what not turned off. Unless of corse you need it on.

To check this go to System Preferances > sharing and check what you do and dont have ticked. Connecting to a public network isnt the most secure to be honest ,but if it is a college or a uni network then i can imagine it has some proxy configuration and a college Firewall managed from you local IT admin dude.

hope this helps 🙂

Thank you for the star. Hope you have found all that you need; you were right to ask the question, you can never be too secure.

As Seventy one said, thaks for the star and good luck
