If you own a Mac and an Apple TV, you likely spend a great deal of time streaming content from your computer to your TV, through Apple’s set-top box. Apple has made this quite easy, starting with Mac OS X 10.8, with AirPlay Mirroring. Yet this can be glitch when streaming long-form content, such as movies, and is not the most practical solution; in addition, you might still be rocking Mac OS X 10.7 or lower.
