    I purchased an apple TV (ATV3) sometime ago. I can stream video perfectly from my iPhone and my wife 's iPad but not from my Macbook Pro When the ATV4 came out, I purchased one and have the same issue. I have tried not mirroring the displays (extended displays), I have tired running CAT5 to the ATV4 instead of using 5GHZ AC wireless. Nothing works. I have also tried my wife's brand new 15' Macbook pro. The video from both MacBooks stutter. When I use my iPhone or iPad, video is perfect. Any ideas on how to make video stream from my MacBooks?

    Did you install the Speedtest app on your ATV4 and check the connection speed? That would help you narrow down whether you're having issues with your home network configuration or if the internet is just slower than you though.

    I don't have the speediest app but I will try that. But I don't think it is the network because my iPad and iPhone use the same network and they work great with the ATV3 and ATV4. It's just my Macbook Pro and my wife's macbook pro. I have also connected the ATV4 to my network switch with a short CAT6 cable and it made no difference so I know it's not my wireless network. I constantly get wifi speeds of 878Mbs on both MacBooks no matter where I am in the house. I have also tried two different AC routers and get the same results. The video is just not smooth using either Macbook.

    Plus, with the speedtest app isn't that just checking internet speed? I get 85Mbs upload and download on both the macs to the internet using FIOS.

    the aTV only has a 10/100 port so your wireless is probably faster.

    speed test really won't tell you much, it measures the speed of your connection to the outside world, but all of the streaming you're trying to do is all internal on your local network.
    The easiest way i've found to check internal network speed is black magic disk speed test. You'd need to set up a network share on another computer, and see what the speeds are to read/write to that. You won't be able to test directly to the aTV though.

    mirrored or extended displays should behave the same. as the same conversion and transmission processes are having to happen.
    From what i've seen, even in the best conditions, if you're trying to watch videos, it will be a little jerky.

    If you're trying to playback files to your TV, you'll have much better luck with a program that will play the file directly on the atv.
    such as infuse, VLC, or plex.

    It's just strange to me that the iPhone plays videos really well. It's not as big of a deal now as I have uploaded my videos to the cloud and can play them directly from the ATV4 but it just bugs me that the video is jerky from my Macbook.

    Do the MacBook Pros have regular or SSD drives in them. Maybe 5400 RPM drives?

    How are you playing them on the iPhone?
    If the video isn't playing on the iPhone screen (normally a black screen with airplay icon), then it's sending the file directly to the aTV where it's being played locally.

    If you're playing from the mac. Your mac plays the file, it then has to wait till the image is on the screen, it then captures that image, converts it to a stream, and then sends it to the aTV. But that conversion and transmission has to happen instantaneously so the screens remain in sync. It seems apple chose to sacrifice a bit of quality as opposed to having a delay on the aTV.

    so on the mac it's
    original file -> image on mac screen -> streaming file --network--> image on TV

    on the iPhone its...
    original file --network--> image on TV

    Both Macbook pros have 256GB SSD drives.

    @waw74 has the right answer above. This has nothing to do with the respective speed of the devices and everything to do with how Airplay is handled in OS X vs. iOS. The files have to go through much more processing to do Airplay from OS X except for some video in Safari on the latest versions.

    You need to use one of the apps suggested, or another very easy one is Air Video HD. You set up the server on your Mac, and then, if using an ATV3 or older, control the content from the app on your iPhone, or on the ATV4, download the Air Video app. It will play flawlessly.

    If you play your movie from iTunes on a Mac, even if you turn on screen mirroring, OS X (or iTunes) is clever enough not to re-encode it, but it switches to direct streaming of the file.
    What sounds strange, is that iPhone plays without problems, but MBP-s do not.
    a) Have you tried ethernet cable directly between MacBook and aTV?
    b) What kind of router do you have? Could it be that it can't properly handle MBP's MIMO?
    From what you say, I read that your MBP-s connect with just 1 antenna, but they have 3! In AC-mode they should reach above 1Gbps - 802.11ac Example configurations
    Phones do not have that problem, they have just 1 WiFi antenna. Except the 6S which has 2.
