What is minimum Internet bandwidth is required for watching movie online on Mac Mini

Greetings Rahuldel,

Welcome to the Apple Support Communities!

I understand that you are looking for information for minimum bandwidth for streaming speeds while watching a movie from iTunes. The attached article give approximate times for downloading a movie from iTunes based on internet speeds. I would recommend downloading the movie before watching it on your Mac mini so there will be no buffering or interruptions.

iTunes Store: Download times will vary - Apple Support

Cheers,

Joe
