Hey everyone. Currently I have an iMac with an external HDD streaming my movies to my Apple TV3 which works great. Unfortunately my iMac is collecting dust so I am giving it to my father. So anyways I was curious since my now primary computer is my rMBP if there was a way I could stream the movies to my Apple TV without having to keep my laptop connected to my external all the time. I'm not sure if this would work or the performance of it but what if I connect my hdd to my airport extreme's usb, then set up home sharing through my macbook and connect my apple tv via ethernet directly to my airport extreme. If it doesn't work or has poor performance, would I be better off replacing my Apple Tv with a Mac Mini and just running the HDD off of that? Any help would be greatly appreciated!
