Ruby

macOS comes with Ruby pre-installed although you may need to update it if you are using an older OS version.

Check the installed version:

/usr/bin/ruby -v

If you have version 2.4 or above you're fine.

Use the following command to install Ruby if you have an older version installed:

brew install ruby

Visual Studio Code

Go to VS Code's website and click on the "Download for Mac" button.

Extract the downloaded zip file and copy Visual Studio Code.app to Applications.

Google Chrome

Go to the Google Chrome's website and hit "Download Chrome".

Open the downloaded .dmg file and drag & drop Chrome to the Applications folder.

Git

Use the following line in Terminal to install:

brew install git
