Download Go on Mac: The Best Way to Install and Configure Go Programming Language


How to Download and Install Go on Mac




Go is a programming language that was created by Google to make it easy to build fast, reliable, and efficient software. Go is open source, cross-platform, and has a rich set of features and libraries. Go is also easy to learn and great for teams, as it has a simple and consistent syntax, built-in concurrency, and a robust testing framework. If you want to start coding in Go, you need to download and install it on your Mac. In this article, we will show you how to do that in a few simple steps.


Downloading Go




The first step is to download the latest version of Go from the official website. You can find the download link for Mac OS here: . This will download a file named something like go1.20.4.darwin-amd64.pkg, which is the installer package for Go.

Installing Go




The next step is to run the installer package and follow the steps. To do that, double-click on the downloaded file and you will see a window like this:


Click on Continue, then click on Install. You may need to enter your password and click on Install Software. The installer will copy the Go files into /usr/local/go folder on your Mac. This is where Go will be installed by default.


Setting Up Go Environment Variables




After installing Go, you need to set up some environment variables for your Go workspace. The most important ones are PATH and GOPATH. The PATH variable tells your system where to find the Go executable files, such as go and godoc. The GOPATH variable tells your system where to store your Go projects, packages, and binaries.


To set up these variables, you need to edit your profile file, which is usually /.bash_profile or /.profile. You can use any text editor to do that, such as nano or vim. For example, you can run this command in Terminal:


nano /.bash_profile


This will open the nano editor with your profile file. Then you can add these lines at the end of the file:

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


The first line adds /usr/local/go/bin to your PATH variable, so that you can run go commands from anywhere. The second line sets your GOPATH variable to $HOME/go, which is a folder named go in your home directory. This is where you will store your Go projects.


After adding these lines, save and exit the editor by pressing Ctrl+O and then Ctrl+X. Then reload your profile file by running this command:


source /.bash_profile


This will apply the changes immediately. Alternatively, you can log out and log back in to your Mac.


Verifying Go Installation




To verify that you have installed Go correctly, you can check the Go version by running this command in Terminal:


go version


This should print something like this:


go version go1.20.4 darwin/amd64


This means that you have installed Go 1.20.4 on your Mac.


You can also write and run a simple Go program to test your installation. For example, create a file named hello.go in your home directory with this content:


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


Then run this command in Terminal:


go run hello.go


This should print this output:


Hello, world!
