These instructions are written for OSX High Sierra, but the installation steps should be the same on all supported versions of OSX:
- Go to http://code.visualstudio.com/ and download VS Code for macOS. This will download a zipped file named VSCode-darwin-stable.zip.
- Double-click the zip file to extract its contents. Drag the resulting Visual Studio Code.app file into your Applications directory.
- Once Visual Studio Code is in the Applications directory, it is installed, and there are no further actions to take.
