The easiest way to install a number of Unix style applications and open source software onto macOS Big Sur, Catalina, Mojave and earlier Sierra OS versions is via a package manager, unfortunately, macOS Big Sur doesn’t come with one, but fortunately, some good folks care, they come in the form of Homebrew.
The install of Homebrew also works on macOS Catalina, macOS Mojave, (High)Sierra, El Capitan, and Yosemite, so macOS 10.10 – 10.14
To download install Homebrew run the install script on the command line as below and let the script do its thing:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
If you don’t have Apples Xcode Command Line Tools installed it will alert you to that it will install it and carry on with the Homebrew installation and download the Command Line Tools you will need to enter your admin password at some point.
Then Homebrew is installed.
After this Homebrew is installed and ready to install other apps.
To get started run brew help can give some command example usage.
To check for any issues with the Homebrew install run:
One issue that typically comes up is an outdated or missing version of Xcode.
For the latest macOS, brew doctor will warn that the Homebrew install won’t be 100% if Xcode is not up to date, so update Xcode from the App Store.
To search for an application:
brew install packagename
To list all apps installed by Homebrew
To remove an installed application
brew remove packagename
To update Homebrew itself
To see what packages are out of date but not to upgrade them
To see what upgrade packages all or singular
brew update brew update packagename
To hold a package at a certain version
brew pin packagename
To release a package from a certain version
brew unpin packagename
To see what else you can do
Where does Homebrew install stuff …. in the Cellar

You can see your Homebrew configuration by running
The output should be similar to …

All installations via Homebrew are filed independently in the filing system in /usr/local/Cellar and linked into /usr/local/bin which is a directory which allows you to run these commands and apps as if part of the regular operating system.
This directory is also out of the SIP bounds so there should be no authentication macOS error dialog boxes.
