For Mac users, QuickTime Player is the first choice since it is bundled with Mac OS X. For windows users, it’s better to choose VLC Media Player. The main difference between the two players is about iTunes movies. QuickTime Player can play iTunes M4V movies while VLC Media Player can’t play M4V movies directly.
Here, I will be setting the default player back to QuickTime.
Note: For VLC, this has to be installed previously before it can be seen here.
Open The Finder Window - Click on the Folder and - Open the video you wish to play - Right click on the Video - Select get Info as shown below.
- Under Open with, Select your desired player. Finally, Click on Change all- That is all :)
