About installing and developing common Lisp on a mac

There are several ways.

Package Manager allows you to consolidate each piece of software into a single package for easy installation.Install the package manager first, and then install the package from the package manager.

The CLISP home page introduces only one package manager for Mac ("Get CLISP")

Homebrew

This is one of the most popular package managers for Macs.As of January 2019, I personally recommend this.

MacPorts

This is one of the most popular package managers for Macs.

Fink

This is one of the package managers available on Macs.

It's a method for people who are used to it.The CLISP source code has been published, so you can build and use it yourself.

If you install from the package manager, you have to wait for the package to be updated even if the software is updated.If you can't wait for this, you'll have to build it yourself.
