Hello John, I figured it was a signal issue. All the speakers fire and the sound is great. I was running the speakers thru a Dell PC with a Creative X-Fi Elite Pro, THX Certified, 7.1 soundcard using a fiber optic from the Mac Pro to the Z906's, it worked great until the Dell died!!! When I bought the soundcard from Creative I also bought the GigaWorks S750, THX Certified, 700 watt, 7.1 speaker system, used the speakers for 11 years and then the woofer/amp said "I QUIT" Creative quit making the speaker system and the sound card. The satellite speakers from the Creative GigaWorks speaker system still sound great (rated at 78 watt each) and are a little better speaker than the one's that came with the Z906 and the wattage from the 906 is sufficient to drive the satellites without any distortion. Thank you for addressing my issue, you confirmed what I suspected all along, just needed to hear it from someone with the same setup.
One last question, I purchased a Diamond Multimedia USB Soundcard, can't use the fiber optic(not supported by Mac) but the green, tan and black RCA's plug in and produces adequetly. When you plug your 906's into the Mac Pro using the fiber optic how do you set your speaker configuration? When I plug into the mac pro with fiber optic the 'Audio Midi Setup' does not seem to see the 5.1 configuration. Any thoughts there?

Our MacBook Pro, purchased in New York June 2011, has appeared to have imploded upwards, case and mousepad area only, overnight. We've read on the community of other almost similar experiences and wonder if this is a common experience?
Batteries can and have expanded when they are old and their useful life is over. More often than not, there will be a warning generated in the battery display in the menu bar or in System Information>Power. You may use a #00 Phillips driver and take off the bottom of the MBP and take out the battery.

27" iMac (refurb, June 2011) not working as an external display for my MacBook Pro.
I just got a 27" iMac (refurb, June 2011) and it's not working as an external display for my MacBook Pro (not Thunderbolt). Any idea why? Command+F2 does nothing. I am connecting via Belkin Minidisplay Port-to-Minidisplay Port adapter.
Any help is appreciated...thanks!Currently the ThunderBolt iMacs can only be used as an external display by other ThunderBolt Macs.

Apple is very clear about that.
2009 and 2010 27" iMac with a Mini DisplayPort can be used by other Macs with a MDP-to-MDP cable.

I need to know which update(s) I can apply to help stabalize the system.
Typing the body of the thread message in the title, huh? -)
I am working on a MacBook Pro (13-inch, Mid 2009) with boot camp running Windows 7 pro 64-bit. Windows crashes quite often now-a-days and I need to get this fixed. I heard that updating boot camp can help. Currently I am running Version 3.0.4 (322).
Only Apple could hamstring and tie Mac OS to Windows. There isn't any other than whether you can download the drivers into Windows (you can) but Apple puts a block on the installer setup even if your mac does not support it.
Windows 7 needs at least Boot Camp 3.1 and 3.3 is what you should already have. And you are not getting security updates if you don't have at least 10.6.8 as was pointed out. --- you arent using Software Update as you should. And you should backup and clone Mac (and Windows) as well.
You need Mountain Lion to use Boot Camp 5.x which supports Windows 7 & 8 and 64-bit.
I would upgrade to Lion if you can realizing that Rosetta and PowerPC are no longer supported though.

Is there a download of the Boot Camp 5 Support Software if I'm not using OS X Mountain Lion v10.8.3?
Yes, you can download the Boot Camp 5 Support Software here.
http://support.apple.com/kb/DL1638
How do I use the Boot Camp 5 Support Software I downloaded from the web page?
The download file is a .zip file. Double click it to uncompress it.
Double-click the Boot Camp disk image.
Copy the Boot Camp and "$WinPEDriver$" folders to the root level of a USB flash drive or hard drive that is formatted with the FAT file system (see question below for steps on how to format).
Install Windows, leaving the flash or hard drive attached to the USB port of your Mac.
Installation of the drivers can take a few minutes. Don't interrupt the installation process. A completion dialog box will appear when everything is installed. Click Finish when the dialog appears.
When your system restarts your Windows 8 installation is done.
Note: If the flash drive or hard drive was not attached when you installed Windows and was inserted after restarting into Windows 8, double-click the Boot Camp folder, then locate and double click the "setup.exe" file to start the installation of the Boot Camp 5 Support Software.
How do I format USB media to the FAT file system?
Use Disk Utility to format a disk to use with a Windows computer. Here's how:
Important: Formatting a disk erases all the files on it. Copy any files you want to save to another disk before formatting the disk.
Open Disk Utility.
Select the disk you want to format for use with Windows computers.
Click Erase, and choose one of the following from the Format pop-up menu:
If the size of the disk is 32 GB or less, choose MS-DOS (FAT).
If the size of the disk is over 32 GB, choose ExFAT.
Type a name for the disk. The maximum length is 11 characters.
Click the Erase button and then click Erase again.
Which versions of Windows are supported with Boot Camp 5?
64-bit versions of Windows 8 and Windows 7 are supported using the Boot Camp 5 Support Software. If you need to use a 32-bit version, you need to use Boot Camp 4 Support Software, and you must use Windows 7. 32-bit versions of Windows 8 are not supported via Boot Camp.

I have tried repeatedly to get my address book on my imac w/ snow leopard to sync to my ipad 1 correctly and have failed every time. I only get about 1/3 the number of contacts and they don't all even correlate with the ones on the imac. Like one will have full middle name and the other only the initial. I don't know where itunes is getting these contacts but doesn't match those in my address book. I keep telling itunes to replace the contacts on the ipad with those on my mac but it doesnt work. Can't do it with icloud cause snow leopard doesn't support, it still wants to use the non existant mobile me format. Hope someone can help. I added the all amnually once before but they screwed up when I sync each time.
Thanks for your response Ernie. You are correct in that whenever you type a series of letters, Address Book (as it always has) finds every single thing with that combination of letters - Names, businesses, adjectives, people's dogs' names, letters in product serial numbers, etc. This is useful for finding a subject on the Web, or finding all documents related to 'iPhoto' on your Mac, etc., but not useful, quick or convenient when trying to find one person to call in your Address Book (which is what people use Address Book for).
What is DIFFERENT in the Snow Leopard version, is that the ability to type one letter to instantly go to last names with that letter has been removed. Previously, you could easily find 'Bill Tilman' in one second by simply typing 'T'. Now you get every word that starts with T and all the words in the card that have a T in them. If you type out a full name like 'Bill', it finds every person named Bill. No one would ever want to find all their contacts named Bill to call them. You could type out the full last name 'Tilman', but there again you are forced to type out a complete name to do a search. It would actually be quicker to scroll down and find it manually. The ability to type a single letter to find the last name (or business name) of a contact you needed to call, was much quicker and easier than having to type out the entire name. -

Zap the PRAM and Reset the SMC; then, try again.

I have a MacBook Pro 2011. I allowed updates to install for iTunes software and Microsoft office (I think). After rebooting, computer wouldn't progress past grey apple screen with loading circle. No progression bar ever appeared. It just sits and spins. I tried rebooting with Command + Option + R + P and hearing the chime twice....this did not work.
I also tried Command +Option+R which took me to internet recovery. From there, I chose reinstall Mac OS X Lion 10.7 but it says my hard drive is locked so I wasnt able to select it. What do I do???? Help! I don't want to lose my files and it doesnt appear that I've used Time Machine Back Up.macbookpro2011ISU wrote:

I you upgraded to OS X 10.8, then use RecoveryHD by holding Command R at boot time (no option) and reinstall OS X over itself that way so your installing Mountain Lion.
Also Disk Uility can be used to Repair the Macintosh HD parttion.
Also you can use that RecoveryHD to format and install OS X onto a external drive, then option/alt key boot from it and access your files on the non-booting internal drive before erasing, reformatting and reinstalling OS X fresh.
Create a data recovery/undelete external boot drive

I have a 2009 imac model with the osx with latest updates to 10.5.8.... and I can not get more upgrades ...
I need to upgrade to 10.6.7 or later in order to buy osx lion....
what can I do...??
thanks
petohttp://store.apple.com/us/product/MC573Z/A
or the family pack of 5 licenses
http://store.apple.com/us/product/MC574Z/A
Buy it quick, as many feel that when Mountain Lion comes out SL disks will go to the secondary market at more than $29 for single or $49 for family-pack
Make a good backup first, preferably a clone, as you may need it if the upgrade does fail. -
I have connected my laptop to a separate monitor but it is only bringing up the background image, not the programs that are open. Help? I assume there is a simple solution. Thank you in advance.
That's called extended desktop mode. You can think of it as an extension of your main screen probably off to the right. Drag an app off the screen to the right and it will appear on the second monitor. You can see and adjust placement of the second monitor in System Preferences > Displays > arrangement tab. Drag the second screen around for your optimum placement. Also the little bar can be moved to either screen and that determines which screen will contain the dock/menubar.
Also you can toggle between Mirror and extend desktop mode by pressing CMD F1.

Audio MIDI Setup Issue -- "Thru" checkbox greyed out
I received my new PowerBook (DL Superdrive) last week and transferred my files from my old PB (the final 1GHz Titanium model) over the weekend. On my TiBook, I used to plug an analogue radio into the Line In port and Apple Pro speakers (via an iFire) into the Headphones port. I then ticked the "Thru" checkbox alongside the M(aster) Volume Slider in the Audio Input section of Audio MIDI Setup (even in Tiger, once I worked out where the checkbox was -- see <http://discussions.apple.com/message.jspa?messageID=740942>) to listen to the radio through the external speakers and control output volume using the keyboard's volume & mute keys.
Audio MIDI Setup on the new Powerbook has some differences, however, including:
1. In the Audio Input section, the M(aster) Volume Slider IS NOT greyed out, but the "Thru" checkbox on this line IS greyed out., and the 1 & 2 Volume Sliders ARE also greyed out.
2. Clock Source is "Internal Clock" rather than [greyed out] "Default".
The first of these differences has left me unable to set up my audio as I used to. Instead, I've had to run a non-Apple audio application, LineIn, in order to achieve the same result. The trouble with this is that I've also experienced the audio stuttering loop described in <http://docs.info.apple.com/article.html?artnum=302978>, possibly as a result of this app running.
Two questions: First, does anyone have any idea how to get Audio MIDI Setup running on the new Powerbook as it did (does) on the TiBook, so that I can dispense with LineIn?
Second, do any of the other Powerbook owners with the audio stuttering problem have similar issues with Audio MIDI Setup -- is it a common factor/symptom/cause?
PB G4 15" 1.67GHz DL SuperDrive Mac OS X (10.4.4)The audio stuttering issue was resolved by an OS X update shortly after I posted this message, but I never did resolve the other issue, and continue to use LineIn to this day (now on a MacBook Pro C2D.

Left my 6th gen ipod nano in the washer.
Left it by the window for 2 weeks.
Plugged it into itunes, screen was white but connected to itunes. (Could only play from itunes)
Now when i plug it in it just blinks white and does not connect to itunes.
What should i do???(Bought it in January of 2011 if that helps...)
Thank you.Unfortunately, Apple's warranty does not cover user accidental damage. The cost of the repairs is on you.

If you mess up, your normal warranty and Apple Care will be voided. So be very careful if you attempt your own repairs. -
Suddenly no Sound - Audio Midi Setup helps only for a while ...
Hi there,
using my iMac (early 2008) it sometimes happens (since the update to 10.6.8 ?), that I suddenly do not have any sound at all (volume is up, no mute active). After a while I discovered the hint also placed in https://discussions.apple.com/message/15943204#15943204 as a solution once, but it annoys me to have do that every other day or so.
Fast User switching is active and usualy two users logged in, sometimes more (children).
I have not discovered any pattern, that could lead to this phenomenom. Any help appreciated.
Have a great year!
RooXI'm using a Logitech Webcam Pro 9000 (which has a microphone on the side). I have several other devices plugged into separate USB slots: a keyboard, a mouse, my iPhone, and a Roland keyboard midi controller.
I've considered that maybe the webcam/mic combo is the culprit. If USB doesn't work at a constant speed, that could very well be causing the issue! The sound begins to lag badly sometimes when it's working properly, so that there's a multisecond delay between speaking and hearing my voice repeated back over the mic which is another sign that something is wrong. I've also caught it making a strange electronic sound during its "hang" time once it stops taking sound input correctly.
Maybe I should try to use line-in and forgo USB altogether then. I think I'd need a preamp and some sort of converter for that since the Mac Mini lacks a powered mic jack. I'm only a newbie musician so I've never set up such a system but it might be a better solution in the long run.
I'll check to see if it hangs before or after my computer enters suspend mode, that's a good suggestion too. Thank you for your help! -
Will ALL computer's home sharing show up on the "computer's" main menu on the Apple TV screen, and if so, can I switch between computers while they are using the "home share" feature?
This should not be a problem, I have a mix of Apple & PC libraries on the ATV.
Looks like you have another issue going on there, perhaps one of your computers is going to sleep or something. -
Help, new to Mac.. iMac boot but keyboard doesn't work...
Not sure what happened but the mac would now boot to ask for password. The keyboard does not respond. Act as if it not paired. I boot with the OS cd and the keyboard works fine. So I not it's not a hardware issue.
One more note, I put a usb keyboard, and when I type the user name, it appears the keyboard has been remapped.
Anyone seen this?
thx
