How to Enable VIM Syntax Highlighting on MAC OSX

For some people VIM is the primary code editor and some people use it to make minor edits to their code. Whatever your use case might be, it’s always good to have some syntax highlighting. It makes the code more readable and reduces errors.

Syntax highlighting / Color coding is not turned on MAC by default. Turning it on is a very simple task.

Open your terminal, it will be in Applications/utilities folder.

Type in the following command to open up the VI editor preferences file

vi ~/.vimrc

Most probably it will be empty. Whether its empty or not, add this code at the very end.
