There is no fix or solution for this, its been 3 months I have the Apple TV and I already tried everything, tried connecting the internet cable directly to Apple TV, updated the software numerous times, changed the resolution of my computer screen, nothing works, Its impossible to connect your MAC to Apple TV everything else works (iPhone - iPad). Its just lagging and freezing making it impossible to watch anything from your MAC.
Sad thing is I bought it to connect my MAC to my tv and watch movies and it ended up being useless, just waste of my money... What is the use of Apple TV if you cannot watch things from your computer???
I tried being patient and thought I could fix it but after 3 months and numerous attempts I am pretty sure Apple TV"s are garbage. Apple is selling an unfinished product, a product that does not work when you connect your MAC, Its just incomlete, buggy or I dont know just not doing what it should be doing.
I am just sad and angry to myself for buying this crap TV....
P.S: Forgot to write, everytime I go to the MAC center they tell me I just need to update the software and the solution is in that latest update, they know very well that their product is not performing and that they dont have a solution for it and instead of accepting it they just lie to your face hoping that you go away and waste your time trying to fix something thats unfixable, its been 2 times they sent me home for an update and non of those latest updates solved anything... Its the same old garbage Apple TV still freezing to a point where its impossible to use your MAC on TV
