LuLu Firewall Updated With Native Support for M1 Macs

LuLu, the free and open source firewall for macOS, updated with native support for M1 Macs.


With the built-in macOS firewall, you can block incoming connections, but what do you do when you want to block outgoing connectons? You can either use custom host files ( search FSM for host files, there’s a few articles on it. Also, see our GitLab repo for more info ), or use LuLu. Or both…

LuLu is a free and open-source firewall that aims to block unknown outgoing connections, protecting your privacy and your Mac.

I’m pretty sure I’ve mentioned LuLu in the past in articles here and there, as Objective-See/Patrick Wardle creates fantastic security apps for macOS. So today’s article is just to mark the new release of LuLu which has been updated with native support for M1 Macs.

Installing LuLu is simple. Download it here and install like any other macOS app ( mount the .dmg file and drag-and-drop LuLu into the Applications folder ). Alternatively, if you’re using Homebrew, you can install it with brew install --cask lulu.

You can also download LuLu from the project’s page on GitHub.
