This is a problem because I have a TV in the lounge with an Apple TV plugged into it. With an Apple Mac and an Apple TV plugged into a smart or dumb TV, it is very easy to mirror the Mac’s screen on a big TV, but the Mac does not have any support for any other dongles or smart TVs. There are also dongles to plug into any type of TV that provide these features like Chromecast and Apple TV. There are many smart TVs that have built in features to enable devices to connect to them, display programming guides, play media and show streaming video on demand services. Here is how to stream the Mac desktop or videos to a TV without Apple TV. An Apple TV connected to a TV enables you to stream the Mac’s desktop or media files and watch on a big screen.
