Mediahhh

Mediahhh is a Mac program that enables you to watch your favorite TV channels directly from your computer.

With its help you can also keep track of the latest TV shows and check channel schedules.
The utility features a straightforward interface, lets you watch various TV channels, and allows you to toggle fullscreen mode if necessary. It also provides you with an integrated sound adjusting bar.

You have access to TV channels like BBC, ITV, Food Network, CBS, RT, NASA, and many others. The application lets you choose the channel you wish to watch from the panel located on the right side of the interface.

Obviously, you need the Internet connection in order to use this program on your Mac. There's a small chance you'll enjoy watching your favorite TV shows if your Internet connection signal is low.

In my testing, the program occasionally used a large amount of CPU resources (over 30%). Also, it sometimes fails to display information regarding TV shows or channel schedule.

To conclude, it's worth using this application on your Mac as long as you have a good Internet connection signal.
