Your Mac Pro needs to be the new black cylinder version. The silver towers do not support streaming to an Apple TV.

    I am getting message from MacPro that my start up disc is full - but I can't find this "start up disc" and can't figure out what to do to help situation. I've been making a number of imovies, which generates junk files and material that I should toss in the trash, but it is not clear to me  what items I can toss and which items I can't toss. Can you help? Using the imovie "help" support the system showed me under the menu item "go" where the "start up disc" should be - but that wasn't actually available on my menu!  Thanks for your help!

  • Apple TV Gen 2.. Terribly Slow Streaming From Wired Home Network via itunes Windows 7. Please Help

    Hello all, I just signed up for this as i hope to get more results from here than i did waiting 4 hours for a call from apple today.
    I recently purchased an Apple TV Gen 2.. installed it on my Samsung 40" HDTV via HDMI cable and also ran a network cable to my basement where my router, (Linksys 5 port router plus Wireless) is mounted on the wall beside the cable modem.
    just to rule things out i will give some spec's and details before i get further into this.
    My goal is to use my Desktop Homebuilt PC running windows 7 ultimate 64bit to store my Digital Movie Library and stream through itunes all of my digital media to my Apple TV located in another room. Both Apple TV and my desktop windows 7 PC are hard wired NOT WIRELESS.
    My internet connection is cable and tested it this evening several times at  58.9 Megabits per second down and 8 Megabits per second down... (yes that is correct 58mb/s down. this equates to about 7.1 megabytes per second download speeds for reference.
    Now just to rule out my 2 year old wireless router i went and purchased a brand new router today... Same results.
    Now on to the problem details and my findings.
    Using my Desktop PC wired to try and stream Itunes movies from the streaming is absurdly slow.. very slow... i have yet to wait to see what happens after 30 minutes of waiting for a Movie to start.. music also takes a long time to load...
    Music... i can go to icloud funtion which i paid for today.. and click on the same song in icloud and the song starts almost instantly, so does music videos...
    Also previously purchased TV shows starts playing from the cloud almost instantly as well even HD TV shows...
    Trying to stream anything through my desktop windows 7 pc just doesnt work right...
    I have narrowed this problem down to my desktop.. but can not figure out what the problem is...
    using my macbook air 120GB SSD wireless over the same network, which i also have a mirrored copy of my itunes library for testing purposes... there is zero issues with streaming anything from my macbook air over the same network via wifi...
    Also using my ipad 2 mirroring works flawlessly, even HD movies plays without a hitch... same goes for my iphone 4s
    the only issues i am having are with my desktop and streaming from my itunes libary on it... i do not want to use my macbook air.. as that defeats the purpose of having apple TV.. in the future i plan on ripping my entire DVD / Blueray collection to a 3 TB hard drive and stream to my AppleTV...  from my desktop computer storing my entire DVD / Blue Ray library digitally on the 3TB hard drive....
    But i can not get this to work...  i can see my itunes libary on my desktop.. i can play music and watch movies.. other than anything HD will not play... but everything takes a rediculously long time to load... i can download an entire movie with my 58mb's connection in the time it takes to load something streaming from my itunes libary on my desktop PC...
    if anyone has any suggestions.. there may be something i have overlooked or i am missing. any input and or advice will be greatly appriciated.
    Thanks,

    Ok.. in order to help other users i will post this..
    I have resolved the issue... it was rather simple and dumb...
    I never use windows media player ever.. i do not like it and can not stand it.. because in my case it was a brand new windows installation this fix will only apply to certain users..
    because it was a brand new windows installation.. i had never clicked on windows media player.. apparently streaming settings are embedded into windows media player for the windows 7 OS...    in past installations that i have used for years.. i simply never ever clicked on windows media player, as i never had a reason to.. i use itunes for my ipad, iphone etc.. etc... 
    by accident and shear luck i decided to click on windows media player.. and of course go through the express settings....  after i did this all of my streaming problems to my apple tv gen2 disapeared... HD movies now start almost instantly... so as i stated above apparently there are media streaming settings embedded into the OS through windows media player... doesnt make any sense to me as i never use the program.. but whatever that fixed my issue..
    so for any of you windows 7 people out there using a windows 7 pc as your itunes sync computer and using that itunes library to stream to your apple tv... make sure you have done the initial setup at min.. of windows media player.. i still left itunes as my default player....  everything now works flawlessly... infact for whatever reason.. even in an HD movie my network almost has half the movie synced now accross the bar before the movie starts so now my apple tv is blazing fast....
    i have been struggling with this for 2 days now and simply never gave it a thought that windows media player would ever have anything to do with itunes streaming a totally seperate program.. but it did..
    i hope this helps other people with similar problems.
    good luck

  • How do I get MacPro iPhoto events downloaded to my iPad mini? Uploading photo streams from mini to Mac works fine.

    How do I get MacPro iPhoto events downloaded to my iPad mini? iCloud is set up. Uploading photo streams from mini to Mac works fine.

    Set up the events as albums on your Mac Pro in iPhoto. Then use iTunes to sync your iPad.
    Start iTunes on your Mac Pro. Connect your iPad and select it in the left sidebar. If you do not see a left sidebar use the View menu to View Sidebar.
    Once you select your iPad look in the right window and find the Photos tab. Select the album or albums you want copied from iPhoto on your Mac Pro to your iPad. Then click on Apply.

  • HT204400 Trouble with streaming from my iphone and on Netflix on Apple TV since an update. I've tried swapping leads, reseting etc... Can ayone help?

    I had Apple TV up and running for about 3 weeks. All good... then I get an update. Since then I've got the HDCP error, so Netflix doesn't work, nor can I stream from my iphone. By shear coincidence, my Sky TV has flagged up the exact same issue at the same time, despite being problem freem for 3 years ?? So nothing on my TV except YouTube. Looking at the amount of forum content on this matter, Apple know this is a problem.
    It's too much of a coincidence not to be related. I requested a phone call at 8:45 this morning, which happened to be 9:00, so I'd left the house. The useless guy said he'd email me something to help..... and I'm still waiting for that email.
    I've tried swapping HDMI cables, resetting Sky and Apple TV, resetting the router, changing resolution in the Audio Visual settings, switching on in different sequences.... I'm lost with it.
    Is Apple now run by monkeys ?  This is beyond a joke. How can an update ruin everything ?
    Can anyone help or am I just to return for a refund ?

  • A friend of mine was recently in an accident and we need to delete some photos from her iPhone's "Photo Stream From my Computer" album, but cannot figure out a way to do it (there's no delete button). Help?

    A friend of mine was recently in an accident and we need to delete some photos from her iPhone's "Photo Stream From my Computer" album, but cannot figure out a way to do it (there's no delete button). Help?

    Sounds like it was synced from her computer using iTunes.  Connect the phone to her computer, open iTunes, click on the name of her phone in iTunes, go to the Photos tab and see if this folder is checked.  If so, unchecking it and syncing will remove them all, or deleting/moving the photos from the folder on her computer and syncing will remove the deleted/moved photos.

  • How can I see My Photo Stream from two Macs associated with the same Apple ID?

    I have a MacBook Pro (my personal machine) and an iMac (our family computer).
    The iPhoto library housing all of our family photos lives on the iMac.
    The iPhoto library on my MacBook Pro is currently empty.
    I have an account on both machines.  I have associated the same Apple ID with both machines.
    When I launch iPhoto on my MacBook Pro and attempt to turn on photo sharing (so that I can see My Photo Stream, as well as other shared streams), iPhoto informs me that "iCloud Photos for xxx@xxx is being used with another library named 'iPhoto Library'."
    My iPhone, which is also affiliated with the same Apple ID, shows the streams just fine.
    What can I do to remedy this situation?  I'd like to be able to view my shared streams on my MacBook Pro, while leaving the actual massive photo library on the iMac.

    I found out about this issue when I created a new library with some photo's I wanted to sync to my iCloud account.  I found the following on the Fat Cat Software page and thought it might be helpful to others:
    Using Photo Stream with multiple libraries
    Starting in iPhoto 9.2, Apple introduced a new feature called Photo Stream, which lets you automatically transfer photos via their iCloud service between your iPhoto library and your other devices such as an iPhone, iPad, or another Mac. This feature works when you have multiple iPhoto libraries set up, but there are a couple things to be aware of.
    First, iPhoto will only allow Photo Stream to be active in one iPhoto library at any given time. If you've already enabled Photo Stream in one library, but then open a second library and enable Photo Stream there, this will cause Photo Stream to be turned off in the first library.
    Any photos downloaded by Photo Stream are actually stored in an entirely separate location from any of your iPhoto libraries. This means that, even if you do switch Photo Stream from one library to another, you will not need to go through redownloading all the photos you already have in Photo Stream back from the iCloud servers. So, switching Photo Stream from one library to another is a relatively inexpensive operation, so you can do it as often as needed without it being much of a hassle.

  • Apple TV: Sync with iMac & stream from PC/Vista?

    Happy New Year to all --
    I have my main iTunes library on my Mac (box iMac, not portable) upstairs, and I have been syncing that library to my Apple TV downstairs. The syncing occurs, and I can listen to my library through my speakers which are connected to my Apple TV. This is setup fine. The only thing I don't like is that the Apple TV's options for playback are very limited.
    I have a subset of my library on my laptop PC (running Vista). As this is portable, I'd sometimes like to stream music from this PC to my remote speakers which are connected to my Apple TV. Then I can use the iTunes interface on the portable to make playlists, plan upcoming songs, etc. on the portable and have the music streamed to the Apple TV and out the speakers. This I cannot get to work consistently.
    So, I want to sync to one computer and stream from another. I do not have to do this simultaneously of course, I just want the flexibility that the iTunes interface has to offer, closer to the listening area.
    I have tried many, many things. Rarely I can get the PC's iTunes to recognize the Apple TV, but when it does, the streaming is unlistenable (consistent dropouts). Today I haven't been able to get iTunes to even recognize the Apple TV's existence. I have rebooted everything (incl network/router), made sure all SW is up to date, changed channels, made sure PC is looking for the Apple TV, made sure UDP 5353 is open, etc etc. to no avail. My network is 802.11g and the signal is strong everywhere.
    I thought this was possible, even desirable, and I also thought that the days of lousy audio streaming was largely over, since video is now being streamed with some success. My network is busy (two tivos, three computers, PS3, Apple TV) but not using a lot of the bandwidth most of the time.
    Any help would be greatly appreciated!! Thanks.

    David
    Multicast rate.
    The multicast rate determines the minimum data transfer speed allowable for a transfer to take place, setting a high value may well make a more robust network but it may simply never allow a transfer if this is too high. I have mine set at 2 Mbps (although I can't be sure you have such an option on your router - sorry I thought you were using an airport.
    Channel
    I couldn't suggest a channel, it all depends on which channels those around you are using, you'll likely need to try a few options unless you actually know what all the other networks around you are using. Other devices (cordless phones, microwaves etc) can also cause interference.
    Is it common to be able to stream to the ATV (i.e. see it in the remote speakers pull down menu at the bottom) but not have it recognized as a device in iTunes (i.e. in the left column)? That's what sometimes happens to me.
    I wouldn't actually know, I've never had any problems with networking my tv's, although network requirements for the tv and airtunes are not the same, so I suppose it's entirely possible that airtunes will be available while you are unable to access the tv.

  • Can't Get ATV to Stream from iTunes

    OK, I can't get my ATV to stream from my iTunes. when I initially set up the ATV, it synced to my iTunes. I actually don't recall any option to sync or stream, but makbe I missed it.
    Anyway, the help says the following:
    "Playing your iTunes library on your TV using Apple TV
    If you have an Apple TV, you can stream items from your iTunes library to your TV. You can also sync your Apple TV with your iTunes library so that content is automatically loaded onto your Apple TV.
    Syncing your Apple TV with iTunes
    If your Apple TV is synced with an iTunes library, it is already set up for streaming. You can also stream items from an iTunes library that isn't synced with your Apple TV. You can stream from up to five iTunes libraries, plus the library the Apple TV is synced with.
    To set up your Apple TV for streaming:
    Make sure the computer you want to stream from is on, and iTunes is open.
    On your Apple TV, choose Sources, choose "Connect to New iTunes," and make a note of the passcode displayed.
    In iTunes, select the Apple TV with "Click to set up" next to it, and enter the passcode.
    While content is being streamed, the computer must remain on and iTunes must remain open. If you stream content while Apple TV is syncing, the sync pauses until streaming stops.
    You can stream from only one iTunes library at a time. To stream from a different library, choose Sources on your Apple TV and then choose another source."
    Now, here is the problem:
    1. It says "If your Apple TV is synced with an iTunes library, it is already set up for streaming." NOT. No where do I see any stream or share selection. Only sync.
    2. It says "You can stream from up to five iTunes libraries, plus the library the Apple TV is synced with." Again, not that I can see.
    3. It says "On your Apple TV, choose Sources, choose "Connect to New iTunes," and make a note of the passcode displayed." I don't have a "Sources" option anywhere in ATV. How am I supposed to select it?? All I have is a "Computers" selection, which shows me my current selected computer for synching, and another option to share a library, with a new passcode. But, only to a second computer, not my main one (where all the files are!).
    I don't understand. It's like it's referring to some other device, with different menus. Now, I have ver 2.0 of ATV, and 7.6 of iTunes. WHAT IS GOING ON?
    I purchased this thing to take advantage of streaming, for photos and video. I only bought the 32 GB unit, but even the 160 would not be bug enough to have all my photos and HD video. So, streaming is a must. But, it would be nice to also sync the music files so I can listen to them without having the computer on. If the thing functed like the manual says, I would be happy. But, it doesn't.
    HELP!!

    Good news- this is all so much simpler that you think. (I know because I too struggled with it for days.) It turns ou that you have to do NOTHING to set up streaming with 2.0. Once you have synced your computer, just leave your computer running and on your TV using ATV you will see whatever movies you have imported into iTunes in the movie menu even if you have not synced them. The only way that you can tell that they are not synced is that when you select them to play the streaming bar will appear briefly at the bottom of your TV screen to indicate that it is being synced. If you turn your computer off the movie that you have chosen would not even appear in the menu.
    Hope this helps- it is too bad apple doesn't give more info about using ATV!

  • Streaming from multiple user accounts......problem

    With my initial set up I had no problem. I have a large iTunes Library. 48k songs. Over 270 GB of files. I synced a few photos and some music for the AppleTV slide shows but everything else I was going to stream. Streaming is working wonderfully from MY user account but if I try and stream a similar sized library from another user account on the same computer it is "NO JOY". I get the "loading library" dialog with the little circle of dashes going round and round but it eventually gives up and does not load. I have tried this with iTunes running on my user account and with iTunes turned off on my user account and either way the library from the other user account will NOT load. I am at a loss here. The set up for the second user went smoothly. I clicked add a library and got a key code on my TV screen. AppleTV showed up in the devices column in iTunes of the second user account and accepted the key code but like I said earlier the library will just not load for streaming. Streaming from my first user account is still working well. I have not found any discussion topics dealing with streaming from multiple user accounts. Hopefully someone who is doing this will chime in and help me out if possible.

    The only way I have been able to get this to work is to quit the iTunes that I am currently streaming from. Switch (on the computer) users to the library I want to stream from. Start iTunes on that user. If I follow this I can get AppleTV to load the library of the second user. If I do NOT quit iTunes from the first user it will not load the second user's library. If I have iTunes from the second user running at the same time I quit the first user's iTunes it will NOT load the second users library. I guess it is a bug and will need to be fixed with the next software release. I would like to be able to switch among user libraries at will and independent of which user is currently using the computer.

  • Why is music streamed from my MacBook Pro to Apple TV via AirPlay choppy?

    I'm trying to stream music from iTunes on my MacBook Pro to my new Apple TV via AirPlay, but the music is extremely choppy, cutting in and out. It's completely unlistenable. However, I can use AirPlay to stream from my Macbook Pro to my Pioneer VSX 1021 AirPlay enabled receiver with no issues. Additionally, I can stream from my iPhone or iPad to the Apple TV without these issues. Therefore it would appear wifi bandwidth is not the root cause. I'm stumped. Help!

    Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
    You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
    Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
    There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first.

  • TS3989 how can I share a photo stream from my mac? there's no check box in system preferences to turn it on

    I've been having trouble to share my photo stream with other from my mac. Once I selecte the photos and click share>photo stream, nothing else happens. The option for "new photo stream" does not appear, neither the field where you type in the email addresses from people you whant to share it with. I all ready checked in iphoto'11> system Pref.> photo stream and there's no "shared photo strem" check box to turn on or off... I also checked in my mac system pref to be sure that my icloud is enabled and it is.
    If I select photos and then go to my tool bar and press share. the option of photo stream is not available.
    I also can't accept any shared photo stream from other and view it in my iphoto. I can only access it via web.
    I DO can use my photo stream correctly and share it via my iphone. and every picture that I take uploads into my mac and every photo I import from cameras into my iphoto also uploads fine into my Ph stream. THE PROBLEM IS THAT I CAN'T SHARE THEM FROM MY MAC.....
    Please can someone help me?

    You turn on Photo Stream in iPhoto's Photo Stream preference pane:
    Check the box "Automatic Upload" to add every photo imported into the library to the Photo Stream.  Or leave it unchecked and manually add just selected photos to the stream by dragging them onto the Photo Stream heading in the left hand pane.

  • How to stream from iPad to apple tv via airport express with the airport express being connected to the internet

    I have an apple tv, iPad 3 and airport express. Im at school and the apple tv is technically not supported by the network. Ive read that one could use AirPlay to apple tv via AE.
    Can someone help me make this work? Step by step process if possible.
    Thanks in advance,

    The router does provide WIFI, but the thing is the Apple TV will be out of reach. I want to avoid having two routers / networks. That's why Apple TV is hardwired. The AirPort (also hardwired) should only work as a receiver for the iPhone - streaming iPhone content to the Apple TV.
    BOTH the Apple TV and the AirPort Express are AirPlay "speakers." That is, you can stream from iTunes to either device. You don't need both if the Apple TV is hardwired to an existing router. That provided the necessary networking for AirPlay to stream over. Wi-Fi is NOT required for AirPlay if you have a wired connection between the AirPlay "server" (i.e., iTunes host) and the AirPlay "speaker."
    The Apple TV would work as a "receiver" for your iPhone.
    If AirPlay is an application layer software, how may two AirPlay device communicate directly? Normally all communication is relayed by the access point.
    AirPlay is a streaming protocol that runs over TCP/IP. AirPlay "speakers" DO NOT communicate with each other directly. The basic communication path is between an AirPlay "server" and an AirPlay "speaker" or multiple "speakers." Again the path between them can be either be wired or wireless or some combination of each.

  • Wirelessly stream from macbook to tv with only coaxial input

    I was hoping for some help. I travel a lot and end up in hotels with TV's that only have a coaxial cable input. Is there a way and what products do I need to wirelessly stream media mostly video from my macbook to a tv with coaxial input only. I have a RF converter so I can stream from an ipod to TV's like this. But I would like to stream items on my laptop. Since this is typically for travel, I dont need advice about using an apple tv, etc. Was just hoping someone would have been in a similar situation and can offer me some inexpensive and easy to travel with advice. Many thanks in advance.

    The Late 2008 model 5,1 Aluminum Unibody and the Late 2009 model 6,1 and Mid 2010 model 7,1 White Unibody have a Mini DisplayPort. The Early 2006 model 1,1 through Early 2008 model 4,1s plus the Early and Mid 2009 model 5,2s have Mini-DVI ports.
    The Mini-DVI to HDMI doesn't carry audio. If you connect the MacBook using a Mini-DVI to HDMI adapter you will probably need to use external speakers or a 3.5mm stereo headphone jack to RCA sound plugs connected to a stereo system for audio if your TV doesn't have separate RCA input plugs or a 3.5mm stereo input plug for audio with the HDMI plug.
    The Mini DisplayPort to HDMI doesn't carry audio unless you have the Mid 2010 model 7,1 and there're no audio plugs on most TVs to work with HDMI since it's expecting audio with the HDMI. Check your TV manual to see if it has audio plugs that work with one of the HDMI ports.
      If you have the Late 2008 model 5,1 Aluminum Unibody or Late 2009 model 6,1 White Unibody with the Mini DisplayPort rather than the Mini-DVI there is an adapter that uses the Mini DisplayPort and a USB port to combine video and audio to HDMI. It's only 2 channel stereo not 5.1 Dolby Surround.

  • E1000 Dies After Streaming from Mac to Apple TV - Needs Reboot Every Time

    Hey everyone:
    I got an Apple TV a few weeks back and we've been using it a lot, especially to stream Netflix.  However, another application that I got it for was for streaming iPhoto slideshows and iMovie stuff to the Apple TV with Airplay's screen sharing.  This event scenario has played out several times.....  Screen sharing is up and going and it'll be working great.  All of a sudden the TV will go back to the main Apple TV menu on its own.  Upon further review at this point, NONE of my WiFi (iPhone, iPad, etc.) devices will connect to the network and I have to power cycle the router.  Router lights are on, but no one's home.  At this point, it'll boot back up and then everything will be fine, at least for a while.
    Tonight, I was showing vacation pictures to some family and this same process happened twice.  Since I can't seem to figure out how to stop playing a slideshow in iPhoto and then start it again in the middle, it's very annoying.  Here are some relevant troubleshooting points to consider:
    1.  This network problem (or something similar to it) has happened in the past, but whatever it is, streaming a slideshow really seems to aggravate it.  This seems to be the only scenario that I can do to actually INDUCE the issue.  Periods of long uploads or downloads are fine.  Streaming audio from one device and similar usage seems to be fine, but this scenario fails pretty much every time, and not necessarily right away.
    2.  After having this issue tonight multiple times, I stopped trying to stream an actual iPhoto slideshow and just went into the album and scrolled through the pics one by one.  I did this for at least an hour with no issue.  But with an actual slideshow, it failed twice in 30 minutes or less.  And it's happened before tonight as well.
    3.  It doesn't appear to make a difference what application I'm streaming from on the Mac.  Whether it's iPhoto, iMovie, or even Facetime.  
    MacBook Pro Specs - OS X 10.8.2 - Late 2011 Model
    Apple TV - MD199LL/A, v5.0.2
    Router - Linksys/Cisci E1000 - Firmware v2.1.02
    Anyone else have similar experiences or advice?  I've got a fair amount of devices in my home that use WiFi, but there was nothing irregular going on in the house to generate an excessive amount of internal network traffic or anything like that.  My gut says the problem is with the router, but it's only a few months old, and I've updated the firmware to no avail. 
    Thanks a bunch for any advice you may have!

    OK, so I've done a couple things here and both point to the above post about having two devices doing AirPlay at once.
    First things first....  I ran the Inssider tool and looked over my network.  My signal seems to always be between 50 and 60.  My router is on Ch 6 which seems to be the best choice.  There's one other network on that channel, but it's a very low signal strength.  The other ends of the spectrum are pretty well covered by other networks.
    Does this shed any light on this problem?
    Second - I hard wired my MacBook to the router, then screen shared to the Apple TV.  It was up for at least 15 minutes.  At some point, I looked over and it was no longer sharing, but the network *WASN'T* trashed like it normally gets.  So it possibly got dropped for some other reason.
    Third - I forgot that I have an Apple Airport Express that I normally use to stream music to a radio in my garage.  However, this device can be used as a router.  So I set it up this way and created a 2nd network.  I only put the Macbook and the Apple TV on it.  I've been streaming continuously for about 35 minutes now with no issues. 
    So it would seem that there's a firmware issue with this router that won't allow one device to Airplay to another device.  Does anyone else have any other conclusions or suggestions?  Otherwise, looks like I'll be treating myself to some new hardware after Christmas.
    Thanks very much for your help!
