Introduction

Pi-Hole's primary function is to be a DNS server with the ability to block domains, usually used for advertising, tracking or other unwanted sites. It also features a built-in DHCP Server.

Usually, your router will also have a built-in DHCP server, pre-configured from factory, and for most users this is perfectly fine. But in some cases you may want to run another DHCP server instead of relying on your router's one. This guide will help you understand how a DHCP server works and how to configure it without disturbing your network.

If you already know the networking basics, you can cut to the chase and read just the configuration part

1) Exact regex — Matches major model identifier numbers based on Apple's knowledge base article (more accurate):

^(Mac(1[34]|BookPro1[4-8]|BookAir([89]|10)|Pro7|Book10)|iMac(Pro1|(1[89]|2[01]))|Macmini[89]),\d+$

2) Current or higher regex — Matches model identifiers based on Apple's knowledge base article and may match higher versions before this regex is updated (more future-proof).

brew is a bad neighbor

This isn't a guide about locking down homebrew so that it can't touch the rest of your system security-wise.

This guide doesn't fix the inherent security issues of a package management system that will literally yell at you if you try to do something about "huh, maybe it's not great my executables are writeable by my account without requiring authorization first".

But it absolutely is a guide about shoving it into its own little corner so that you can take it or leave it as you see fit, instead of just letting the project do what it likes like completely taking over permissions and ownership of a directory that might be in use by other software on your Mac and stomping all over their contents.

By following this guide you will:

• Never have to run sudo to forcefully change permissions of some directory to be owned by your account
