Install Homebrew On Catalina

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

Homebrew isn’t the only option, also available is MacPorts and Fink but Homebrew is the newest and most popular of the trio.
