Upgrading From An Older Version On Mac

To upgrade from an older version on Mac, there are a couple manual steps that you need to take. For starters, download the latest installer for Mac from Go Lang Downloads.

While this is downloading, you'll need to delete the older version of Go that is installed on your machine.

First, remove the existing Go installation directory:

$ sudo rm -rf /usr/local/go

Second, clean up the Go bin directory from your PATH environment variable:

$ sudo rm /etc/paths.d/go

Now, you can double click on the downloaded installer dmg and follow the prompt instructions.

When its all said and done, check go version from the command line to see that you are now working with the latest.
