    Default Full OSX on AppleTV - What's the situation?

    Ok, here's another post about the porting of Full OSX to AppleTV... what's the current status? I mean, I'm going to buy it and use it as media center, so I need to have:

    - Full Video working (i.e. no problems in viewing videos from YouTube, Joost etc.)
    - Obviously, full Audio... (I've read somewhere that it doesn't work good)
    - USB DVD drive
    - WiFi
    - If possible, IR receiver and Apple Remote

    Sorry for posting another time about this... but I've found lots of opposite informations, and I want to be sure before buying it.

    By the way, this is my first post, hi to all! Think this is a great community, thanks to all of you!

    I decided to buy a ATV in November to throw OSX on, and only now, after countless hours of research and tweaking, have it 95% working like a real Mac. Luckily, the list of what is not working is llimited to only three items right now:

    1. 3D acceleration (QE/CI) when using the HDMI port. However, when using component this does work. Keep in mind, that even Chess will not run without QE/CI...

    2. Status light always is blinking. However, you can "fix" that by opening the case up an cover the LED with tape.

    3. VERY (emphasis on very) poor performance when running apps in Rosetta, as the processor lacks SSE3, and this is emulated in the hacked kernel. So limit yourself to Universal Apps only.


    Things that will need to be patched/fixed after the OSX.4.11 install:

    Audio (see post below for solution)

    Graphics (Delete all nvidia kexts as instructed by the install tutorials only if using HDMI. Otherwise, leave 10.4.11 kexts alone to get QE/CI)

    Ethernet - search for PCGenRTL8139Ethernet.kext

    Apple System profiler will crash - Patch located here:
    http://forum.osx86scene.com/viewtopic.php?f=16&t=2240

    System time has a bad drift due to hacked kernel. If you need (somewhat) accurate system time, you will need to set up a cron script to call the ntp update daemon at desired intervals (I have mine set at 2 minutes)

    Disk Images do not load correctly. Need to call this terminal command to fix:
    sudo kextload /System/Library/Extensions/IOHDIXController.kext
    I have just created a executable script to run and placed it in my dock to avoid this process. It's a good workaround.


    As you can see, this is not for the time-limited or faint of heart. But with work, it makes a good machine.


    Words of warning:

    Leopard does not work, and probably never will.

    Bootcamp will not work. Windows will never be able to run (because of lack of BIOs emulation layer)
    Parallels/VMWare does run, but keep in mind the limited amount of RAM this machine has.

    There is no power switch. Go buy yourself one of those remote light switches, and use that to power on and off the box.

    The ATV runs hotter than you could ever imagine (almost too hot to touch). Give it lots of space for circulated air.



    Well, I think that is all for now. Should you have any more questions, let me know.


    Edit: To clarify, both WiFi and the Apple Remote work without additional work in 10.4.11

    If I remember correctly:

    You will need to register an account at insanelymac.com before you can download.

    Install AzaliaAudio.pkg, but don't reboot when prompted.
    http://forum.insanelymac.com/index.p...=post&id=19590

    Unzip AppleHDAPatcher 1.20
    http://forum.insanelymac.com/index.p...=post&id=18636

    Drag codec to patcher.
    http://forum.insanelymac.com/index.p...=post&id=10328

    Then reboot.

    You should now have complete support for ALC885. If not, let me know, as I have several other codec dumps to try.

    SummerSoFar, this codec doesn't seem to be working for me, got those other codecs at hand?

    Thanks for the answers... I forgot to ask another thing: is it possible to use it as PVR, i.e. to register programs from my tv? On the TV, I've got S-VIDEO, VGA and HDMI ports.

    thanks, got a final and for me most important question: How good is playback of HighDef content, lets say 720p, working with the full OSX and how good is it working with the original Apple TV software its shipped with?

    The point is, i got an xbox1 running with XBMC as media center right now, unfortunatly its too slow to playback HD content... so i', searching for a new alternative and came across the Apple TV.

    Someone ported XBMC to the Mac and I got it to play 720p content with very low CPU usage. The author claims it also performs well even on a low end GMA graphics card with 1080p HD, however that is using a dual core processor (Mac Mini.) The Pentium M should have enough beef to do HD, but the post of XBMC has 2 major flaws right now:

    1. Not all audio codecs are supported. My 720p test movie had an odd format audio rack and it was all high pitched jittery noise. The video looked great though.

    2. It is Intel and Leopard only, so if Leopard won't run with QE/CI on the AppleTV, then you are out of luck.

    I would still give it a try on a Mac and look at it, as it's a very good and stable port as far as i can tell with my testing:

    A zip file of five different ALC885 audio codecs to try:

    I tried all five of them to no avail. Two made no sound at all, the other three were choppy when playing video.

    Also, I have the same version, but the remote control isn't working for me. Is there anything else you needed to do to get that working?
