New Mac Pro Won't play back

I'm having a problem with my new Mac Pro 2.66 I keep getting the error, "couldn't keep up". I've got maybe 5 tracks (Kontakt 2,Real Guitar, and EXS) and a couple plug ins and I can't get it to play. I press the space bar and it spins for a sec...plays maybe 1 second and then quits...pops up with the message saying it couldnt access info fast enough. I had my samples on a different computer networked via gigabit but some said that was the problem so I transfered them to a seperate internal (sata 2) drive and it still doesn't work. My CPU is either very low or it maxes out 2 or 3 of the cores before the freeze. I can't believe this is happening with this machine. This is why I got a new one. anyways...thanks for all suggestions.

Same problems here without any Native Instruments plugs.
4 tracks at the same time (2 audio and 2 nexus((or any other instruments))
apple says: we don´t now about this problem and because my 90 day!!! support is finish I have to pay 208EUR and than they help me.

Mac Pro won't play radio streams like G5 could

Is it really true that the new Intel-based machines will not ever play live streaming radio broadcasts?
I cannot seem to get this thing to work at all - Flip4Mac, WMP 9.0, nothing seems to work, although my G5 (which is being sold) does. (Some have said that one must run Safari in "Rosetta" mode with the new Intels; if so, how is this done?)
Will this ever be corrected?
Thanks all in advance for your help!
David

Seems strange you can't get audio to work natively.
Your 3 most popular choices: RealPlayer, Windows Media formats via Flip4Mac, and QuickTime.
RealPlayer - do you have the lastest version (10.1) installed? If you do, have a look at your RealPlayer preferences>Media Types (top 4 boxes selected), Internet (Internet settings - 1st and 3rd box; Web Browser - both boxes checked) and Transport (Network Transport box checked).
QuickTime: System Preferences>Quicktime>Advanced>Mime settings>Audio - make sure all are checked (the only one unchecked for me is "sound designer II". Also, the Miscellaneous box is unchecked.
Flip4Mac - System Preferences>Flip4Mac: Plug-in - 1st and 3rd boxes checked; Movies>1st box checked (obviously not audio related, however, good to make sure it's selected).
Let me know if that helps get you back into the Intel Native mode for audio streaming.

Videos on my macbook pro won't play sound after apple tv was installed in the house

Hi! Need some help... for christmas my dad received the little black Apple TV device to watch videos on our big tv from his iPad. After it was installed no sound came from my macbook, it instead comes out of the tv speakers. When dad is airplaying a video from his iPad and I open a video on my mac, the iPad video gets interrupted and the sound from my video comes on without the visual. What's going on?! I see the airplay symbol on the top right bar but it always says disconnected, yet obviously the sound is somehow connected.

that figures, VLC.
Consider getting your dad the APP VLC streamer for his Ipad, that way he can wifi beam movies etc. to his Ipad from any Mac.
removes putting movies on an Ipad and clogging it up with large movie files. Very handy

Airplay mirroring on Macbook Pro won't play sound

Ok, so I just updated the Apple TV to 6.0.2. Airplay mirroring works fine on my iphone and ipad. But when using it on the MBP, it won't let me hear the sound. The output to sound for the Apple TV is selected in the Preferences. I've restarted the MBP and the Apple TV. I've also Reset the Apple TV, but still nothing is working. It's not an app or music; even when I just show the desktop, and hit the volume buttons, usually you hear the tone for the button on the Apple TV. This does nothing now. I just tried Sudo killall coreaudiod, didn't work. Please help!

This is what the sound setting show.

My 15in Pro won't play sound with out headphones.

The red light is on inide the port also. Ive tried wiggling a tooth pic and head phone jacks in gently but no luck. Any help??

Try inserting the headphone jack into the port and wiggle that and then remove. May have to do it several times. Other option is to remove the bottom and work the port switch manually to put it back so it doesn't register that a plug is inserted.

You can't boot OS X with a Windows boot device.
Internet Recovery is the next step. Follow ssls6's advice.

How come some apps won't play sound on a USB device but only on the internal speaker while others can?

You can simply set your system preferences
Sound preference
output - to whatever your USB device/audio interface is
Your question seems a bit vague to me though. So can you actually inform us of what it is you are trying to do and give us examples with named kit.

MacBook Pro won't play .mov or .wmv files.

Since "upgrading" to Lion my MacBook Pro won't play .mov or .wmv files, all I get is a black screen and the audio. It's so frustrating!!
I've read many other posts all along the same lines and wherever possible I've tried to follow the advice which has been given but nothing works.    I've updated all the drivers I can and I've even reinstalled Lion, nothing makes a difference.
I'm not really looking for any more advice, all I want is someone from Apple to read these posts, realise there is problem and get working on a fix or update.
I had no problems when running Snow Leopard and it would seem, looking at everyone else's problems, that the common issue is Lion.   Seriously, this is one area where Lion is a backwards step.   It should just work (like most things from Apple), but it doesn't.
Personally I believe there is a problem with Lion but from what I've found out from speaking to friends with other Apple kit, this might be a random issue only affecting some people as some have said they've had no problems while others have had the same issues as me.    One guy reinstalled Lion and it resolved the issue for him, I've not been as lucky.
As I say, I'm not really looking for more advice, simply some sort of update from Apple to fix it.   PLEASE!!!

This is a peer-to-peer user forum. Perhaps you would see more action if you and others would file a formal "Bug" report with Apple QuickTime technical people rather than repeatedly reporting a possible problematic problem which may or may not affect others on a random basis. QUICKTIME PRODUCT FEEDBACK
Since you aren't seeking further advice here is what I have observed. Not being a regular WMV file user, I had to create my own sample file to test—a WMV 9 file containing WMV3 compressed video and WMA2 compressed audio. Since I normally use QT 7 as my primary media player, I also stored the WMV data in its partially decompressed form in an MOV file container to avoid pre-playback delays in "classic" player routines and also provide a secondary playback test of MOV wrapped content. These files play as follows using the Flip4Mac component/player support and uncoded URL uploads:
QT 7.6.6 "Open File" - both files play correctly.
QT 7.6.6 "Open URL" - both files play correctly.
QT X.1 "Open File" - WMV file plays correctly. MOV file plays video without audio.
QT X.1 "Open Location" - WMV file appears to open but plays with "black" screen and no audio. MOV file plays video without audio.
VLC "Open File" - WMV plays correctly. MOV file doesn't open,
VLC "Open URL" - WMV file plays correctly. MOV file appears to open but nothing plays.
MPEG Streamclip "Open File" - both files play correctly.
MPEG Streamclip "Open URL" - both files play correctly.
GarageBand - WMV file will not import but MOV file does.
iTunes - WMV file will not import. MOV file container is accepted but as soon as iTuness sees the compression formats, it aborts import.
Safari - WMV file URL auto-downloads and playes in the QT X.1 Player. The MOV file URL opens and plays in Safari.
As you can see from these results the files do play but are subject to many different constrints based on old/new video technology support, independent QT subsets and/or container trapping constraints. In short, individual user results will depend on presence/absence of component support, actual compression formats, file container, application being used, and how the application is being used. Unfortunately, most users here can't or won't provide the prerequisite information or a sample file for independent examination. This makes it next to impossible to give advice in these matters or categorize the specific nature of the problem.

Mac Pro won't network after 10.5.8 combo update

I just ran the 10.5.8 combo updater and since then my Mac Pro won't connect to my home network. It accesses the internet just fine, but I cannot connect wirelessly to my Macbook or my wifi printer anymore. My Macbook which is still on 10.4.11 can connect to the wifi printer and the internet, but cannot connect to my Mac Pro anymore. I've seen posts about pulling ktxt files out of the 10.5.7 updater, but that doesn't seem to address my issue. Any ideas? Thanks

Went on my vacation, brought my macbookpro, got home, mac pro won't acknowledge photos. Why?

Wife uses the macbookpro mostly with her iphone. However, they are my photos on my phone, and all computers are mine, so why in any case because I have synced with another computer with also uses another iphone, that my personal mac pro won't acknowledge the photos that originated from my phone. Photos shouldn't be subject to copyright like music purchases. If I decide to share my photos with another mac (which also happens to be my macbookpro that my wife uses), there shouldn't be anything applied to the photos I've taken with my personal iphone once it is plugged into my other mac. They're my photos regardless and originated from my iphone, so my mac pro should never block these photos from me in iphoto.
Summary:
I go on vacation with my macbookpro.
I take photos with my iphone. I put them in my macbookpro while on vacation.
I get home. I try to put the photos on my macpro. Not only am I not allowed, I can't even see the photos in iphone via my plugged in iphone. They are hidden when plugged into my macpro.
Why don't I have access to MY OWN PHOTOS when I have spent well over 50,000 dollars in Apple products?
To fix this I had to export the photos from the macbookpro to a USB and manually add them to my mac pro. Alternatively I could plug in my iphone to my windows computer and access all the files via a folder search.

Another way to look at this which imo also applies.
I go on vacation with friend. I take photos with my iphone. I sync some of the photos to his iphoto on his macbook. I get home.
I can no longer see those photos, which I took, using my own iphoto sync on my mac. They don't show up anywhere with preview or image capture (remembered name). Just because I gave my friend some of my photos, doesn't mean a lock should be applied that doesn't allow me to sync those photos via iphoto on my own mac. Doesn't this make sense? Why is this happening?
