As a developer using Mac system, you may have realized the importance of Golang (also known as Go language) in modern software development. Golang is a programming language developed by Google. It has the characteristics of efficiency, simplicity, and strong concurrency, so it is favored by developers. If you haven’t installed Golang on your Mac system yet and are eager to explore its wonders, this simple tutorial will show you the way forward.

Step 1: Download the Golang installation package

First, you need to download it for Mac from the official Golang website (https://golang.org/dl/) System Golang installation package.
