As a popular programming language, Golang developed by Google has occupied a place in widespread use. If you want to install Golang on your Mac, this article will tell you how to do it.

Introduction to Golang
Golang is an efficient, fast, safe and reliable programming language. It is designed for rapid development in large-scale distributed systems. Golang was developed by Google. Its programming style is close to the C language, but it also adds object-oriented ideas and other modern language features. Golang's simplicity and efficiency make it widely used in writing web servers, tools, and some high-performance applications. Let’s take a look at how to install Golang.

Step 1: Download the Golang compressed package
If you want to install Golang manually, the first step is to download the latest version from the official website (https://golang.google.cn/dl/) Golang compressed package. You will see different versions of Golang. Select the corresponding version to download according to your Mac operating system version.

Step 2: Decompress the Golang compressed package
After the download is completed, double-click the downloaded compressed package and decompress it to the path of your choice.

Step 3: Set environment variables
Open the terminal and enter the following command to add Golang to the environment variable:

$ export PATH=$PATH:/usr/local/go/bin

Then enter the following command to make the configuration variable take effect:

$ source ~/.bash_profile

It should be noted here that if you are using zsh, you need to change .bash_profile in the above command to .zshrc.

Step 4: Verify whether Golang is successfully installed
Enter the following command in the terminal to verify whether Golang is successfully installed:

$ go version

If Golang has been successfully installed, you will see the version of Golang Number.

Step 5: Create the Golang working directory
Next, we need to create the Golang working directory on the Mac, because Golang needs a working directory to work. Enter the following command in the terminal to create a working directory named go-workspace:

$ mkdir ~/go-workspace

Step 6: Set up the Golang working directory
Enter the following command in the terminal to set up the job Directory:

$ export GOPATH=$HOME/go-workspace

Then reload the configuration file:

$ source ~/.bash_profile

Step 7: Create the src directory in the Golang working directory
Enter the following command in the terminal to create a directory named Directory of src:

$ mkdir -p $GOPATH/src

Step 8: Create Golang project
Now you can start using Golang to write code. Create a directory named hello in the $GOPATH/src directory.

Create a file named main.go in the hello directory and enter the following content:

package main
 
import "fmt"
 
func main() {
    fmt.Println("Hello, world!")
}

After saving the code, in the terminal Enter the following command in:

$ cd $GOPATH/src/hello
$ go build

This will compile and generate an executable file for the main.go file. Enter the following command in the terminal to run the application:

$ ./hello

If all goes well, you will see "Hello, world!" output in the terminal.

Congratulations, now you have successfully installed Golang on your Mac and created a simple Golang application.
