Mac OS X: Set / Change Default Application for Specific File Type

It can be a little tricky to change the default application when opening up specific files on a Mac. In my case, I wanted to change from the default Quicktime player application to VLC for file extensions such as mp4, m4v and mkv. ┬áThat’s where Rubicode comes in to save the day, making it extremely easy to manage your default applications on your Mac.
