Go 1.20 is the latest release of Go, which was announced on February 1, 2023. It includes some language changes, such as allowing direct conversion from a slice to an array, and adding new functions to the unsafe package for manipulating slice and string values. It also introduces a preview of profile-guided optimization (PGO), which enables the compiler to perform application-specific optimizations based on run-time profile information. Go 1.20 also improves the tooling and the library, and enhances the performance and stability of the code base.


In this article, you will learn how to download and install Go 1.20 on your Mac computer. You will also learn how to verify your installation by writing and running a simple "Hello, world" program in Go.

Resources and tutorials for learning go 1.20 on mac


  • A Mac computer with an internet connection



  • A text editor of your choice, such as Visual Studio Code, Atom, or Sublime Text



Downloading Go 1.20




To download Go 1.20 for Mac OS, you can follow these steps:


  • Go to the and click on the link for go1.20.darwin-amd64.pkg. This will download the Mac OS installer package for Go 1.20.



  • Open a terminal window and navigate to the directory where you downloaded the file. You can use the cd command to change directories.



  • Verify the checksum of the downloaded file using the shasum command. You can find the expected checksum value on the . For example:



$ shasum -a 256 go1.20.darwin-amd64.pkg f7c0b6c8f5e6c8b9f9e3f3b0c4c7e9e5f0b8b6d7d0a6d9c8b7f3f7f5f6f7e9e5 go1.20.darwin-amd64.pkg


If the checksum matches, you can proceed to install Go. If not, you may have downloaded a corrupted file and you should try downloading it again.


Installing Go 1.20




To install Go 1.20 on Mac OS, you can follow these steps:


  • Double-click on the downloaded file to start the installation wizard.



  • Follow the steps in the wizard. There are no configurations and options to choose from, so its a straightforward installation.



  • Add /usr/local/go/bin to the PATH environment variable. You can do this by adding the following line to your $HOME/.profile or /etc/profile file:



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


This will ensure that you can run the Go commands from any directory.


Verifying Go installation




To verify that Go is installed correctly on your Mac, you can follow these steps:


  • Open a new terminal window and run the go version command. You should see the output showing the version of Go that you installed. For example:



$ go version go version go1.20 darwin/amd64


If you see an error message or a different version, you may have a problem with your installation or your PATH variable.


  • Write and run a simple "Hello, world" program in Go. You can use your text editor to create a file named hello.go in any directory and write the following code:



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


Then, save the file and run it using the go run command. You should see the output showing the message "Hello, world". For example:


$ go run hello.go Hello, world


If you see an error message or a different output, you may have a problem with your code or your Go installation.

FAQs




How do I uninstall Go from my Mac?




To uninstall Go from your Mac, you can follow these steps:


  • Delete the /usr/local/go directory and all its contents.



  • Delete the line that adds /usr/local/go/bin to the PATH variable from your $HOME/.profile or /etc/profile file.



  • Delete any Go files or directories that you created in your workspace.



How do I update Go to a newer version on my Mac?




To update Go to a newer version on my Mac, you can follow these steps:


  • Download the installer package for the new version of Go from the .



  • Verify the checksum of the downloaded file using the shasum command.



  • Run the installer package and follow the steps. It will overwrite the existing installation of Go.



  • Verify that the new version of Go is installed correctly using the go version command.



How do I set up a workspace for my Go projects on my Mac?




To set up a workspace for your Go projects on your Mac, you can follow these steps:


  • Create a directory where you want to store your Go code. For example, $HOME/go.



  • Create three subdirectories inside it: src, pkg, and bin. The src directory will contain your source files, the pkg directory will contain your compiled packages, and the bin directory will contain your executable files.



  • Add the workspace directory to the GOPATH environment variable. You can do this by adding the following line to your $HOME/.profile or /etc/profile file:



export GOPATH=$HOME/go


This will tell Go where to look for your code and where to put the compiled packages and executables.


  • Add the $GOPATH/bin directory to the PATH environment variable. You can do this by adding the following line to your $HOME/.profile or /etc/profile file:



export PATH=$PATH:$GOPATH/bin


This will allow you to run your Go programs from any directory.


  • Create a subdirectory inside the $GOPATH/src directory for each of your Go projects. For example, $GOPATH/src/hello.



  • Write your Go source files inside the project subdirectory. For example, $GOPATH/src/hello/hello.go.



  • Use the go build command to compile your code and generate an executable file in the $GOPATH/bin directory. For example, $ go build hello.



  • Use the go run command to compile and run your code without generating an executable file. For example, $ go run hello/hello.go.



  • Use the go install command to compile your code, generate an executable file, and install it in the $GOPATH/bin directory. For example, $ go install hello.



  • Use the go get command to download and install packages from external sources. For example, $ go get github.com/gorilla/mux.
