I watch a lot of TV shows and movies on my Mac (connected to my TV). But right under my TV is my Apple Tv. I want to know if there is a way, or i need a special app so that I can use my apple remote to control my mac when watching TV shows, but not mess with my apple TV when i use it to control my mac. when I pair the remote to my Mac and try to use it for apple TV its messes with my Mac volume. Do i need a 2nd Apple Remote so i have a seperate one for each?
