Deauthorizing a computer that will not boot

I've been using Itunes for about a decade. Apple limits the number of computers you can authorize to sync your ipod to 5, which I have used. To add another computer though you have to deauthorize one of the other computers. Problem is, 4 of the 5 computers have died, and I cannot boot them. So, how can I sync my ipod to my new computer? How can I deauthorize computers that won't boot, or are at the dump?

Use the Deauthorize All command documented in this article, or if it isn't an option, the 'contact iTunes Store support' link at the bottom of it.

Reinstall OS X.
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
OR
Reinstall Snow Leopard without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

I have a powerPC 8500 that will not boot up.

I have a powerPC 8500 that will not boot up. Lights come on, drives spins up and nothing. Any ideas? It has been sitting in storage for years. I would like to get some info off it.

If you wish to do further testing to insure it is the PRAM battery at fault before ripping into the computer, there are a couple of things that always worked for me if the battery was really the problem:
1) Zap the PRAM--cold boot and immediately press and hold these four keys simultaneously:
command
option
p
r
Keep holding until you here a total of three (3) startup chimes, then let go the keys. NOTE: In some Mac models, the second and third start-up chime tone during a PRAM zap can be rather quiet. Either crank up the volume, do the zap when the room is quiet, of use headphones to be sure you are hearing teh tones.
2) See if the computer will boot from a system disk by holding c during boot. The disk can be a full retail install disk, a system restore disk supplied with the computer, or a utility disk like DiskWarrior or TechTools that allows booting. If the computer boots and you get video, you can feel confident that the only thing needed is a PRAM battery. You can do a hot boot back to the hard drive and the computer should work as long as someone doesn't unplug it again.
However, if neither of these work, that can mean something more sinister than a PRAM battery has gone walkabout.

G4 that will not boot from any disc EXCEPT the Apple Hardware Test CD

We have a DP 1ghz Quicksilver PowerMac G4 that will not boot from any disc EXCEPT the Apple Hardware Test CD that came with the machine.
We were in the process of installing 10.4 Tiger before placing it for sale.
The Mac was originally OSX Server 10.1 that we later converted to a worksation running 10.3 Panther.
It has 1 GB of memory, 80GB hardrive, 250MB Zip Drive and a Radeon 7500 video card.
Since this machine only has a CD-R drive and not a DVD-R, we installed Tiger using another Mac via Target Disk Mode. The installation process went well, but when I tried to reboot I got a Kernel Panic right after startup screen with the grey Apple logo.
On some reboots we get to the blue startup screen, others it stops at the grey Apple logo, others a black box like the a Kernel Panic - but with no text. Twice it went directly into Open Firmware.
We have done the following during our troubleshooting:
- Reseat RAM, Video Card, Hard Drive, Zip & CD-R connections
- Remove RAM 1 stick at a time and reboot
- Replace RAM with RAM from another working Quicksilver
- Replace Video Card with one from another working Quicksilver
- Zap PRAM
- Reset CUDA switch
- Unplug the MAC and remove everything (RAM, Battery, etc) for 30 minutes and try to reboot
- Tried booting from the Macintosh Server G4 Software Restore CD
- Tried booting from Mac OS X Server CD
- Tried booting from AppleCare Protection Plan CD with TechTool
- Tried booting from Diskwarrior CD
- Tried booting from an external FireWire drive with a disk image of Tiger OS Install
- Tried booting with the hard drive disconnected
The Mac WILL boot from the Apple Hardware Test CD and will pass ALL of the extended tests.

Conventional wisdom says that any Mac that will not boot up from a System/Install CD OS 9 or an Install CD Mac OS X, has a Hardware problem.
The diagnostic CD is a red herring because it uses a very primitive method of reading the CD, and so does not properly represent the machines general ability to read CDs.
I would look at the CD drive cables, etc, and see if another drive gives different results.
You have not mentioned using the Startup Manager (option key at Startup) to do any checking:

How do move my music from iPod to a new computer that will not recognize my last iTunes account

My school district installed new computers. The IT told us that our iTunes would not be effected. When I went into iTunes on my new computer, there was nothing there. Obviously I can't plug in my iPod or everything would be erased. They said that there is nothing they can do about this.
How do I move my music from this iPod to this new computer that will not recognize my last iTunes account? It appears that it was wiped out. I have close to 400 songs that I use for daily classes. The os is now Windows 7. The old one was Vista.
Thanks for your help.

I have an old nano purchased in 2006. It indicated new models on the page.
Any other suggestions?

Advice for troubleshooting an emac that will not boot

My mom's emac will not boot, and gets stuck with a gray screen and apple logo along with the circling timer. We have tried the following:
(OSX.2x)
turning off and unplugging computer.
removed all peripherals
reboot in safe mode
reboot from installation disc
nothing works. The computer gets stuck in the boot process. We have run the hardware repair disc, there are no problems with the hardware.
I would like to make as many attempts to troubleshoot problem at home before spending a lot of money by taking it to a repair shop. I would also like some information before I go in order to be prepared to discuss the problem. I do not want to get 'taken' for repairs that may be unnecessary.
Any guidance, suggestions, advice would be very helpful and greatly appreciated.
Thanks!

It sounds as if you've already figured the standard trobleshooting / startup methods. There is one additional thing that can block an eMac from starting: if the PRAM battery is failing, that can prevent the Mac from starting up. My understanding is that a failed battery would block the eMac from starting up to the Apple Hardware Test (AHT) Disk also, through. Perhaps the battery is low enough to prevent a normal start but still has enough in it to let AHT come up? If you have an electronics multimeter, you can test the battery while it's under load (i.e., still in the eMac's PRAM battery holder) and see if it's within 0.1v of the nominal 3.6v specification. If the battery is low, replacing it is straightforward (see eMac - Do-It-Yourself). The 1/2 AA 3.6v lithium battery is available online and is usually in stock at places like Radio Shack, where it costs about US$11 or so (the battery is cheaper online, but after adding shipping and handling, the brick-and-motar store is about the same, plus quicker).

Data Recovery off of a drive that will not boot

I have a server which will not boot into windows, I really just need to grab a few files off of it, I have downloaded several types of software and of course there is a limit on how much it will restore then it wants you to pay, the size is about 52 gb's, I used to use WINPE, does anyone have a piece of software that is free that I can recover this data since I can not boot into windows?
This topic first appeared in the Spiceworks Community

Did you do this:
Repair the Hard Drive
Boot from your Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. Select the external volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. Quit the installer to restart the computer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
See if this works to repair the drive.

My computer is will not boot up. INstead its making a clicking sound and in the middle of screen picture of a file with a question mark. What does that mean?

Does anyone know what's wrong with it? not booting up. instead of it a picture of a file appears with a question mark on it in the middle of screen?

Sounds like abad hard drive. The clicking sound is coming from the HD. The folder with the question mark means that your computer can't find the statrup disk or the hard drive.
Boot your computer using the install disc and check if Disk Utility can recognize your HD. If not, then it needs HD replacement. If you have AppleCare or within the 1 year warranty, then replacement should be free from Apple. Check the nearest Apple Store in your area.

How can I deactivate Photoshop Elements 5.0 on hard drive that will not boot?

I have Elements 5.0 loaded on a hard drive which will no longer boot. I have a new hard drive and can access the old drive as an extra internal hard drive. I cannot use Photoshop, so I was thinking I need to deactivate the copy loaded on the old hard drive and reload it on the new hard drive. Is this the best solution? If so, how do I deactivate? When I start up the editor, it does not have an option for deactivating as I read about in another post. Under the help menu, there is a grayed out option for Registration. After a few seconds, a window appears saying there is a problem with my serial number and the application closes. Also, I would like to load Photoshop on a laptop later, so I do not want to waste one of my allowable loads. I would appreciate any help.

Yes, as long as you don't have it on more than two computers at once you're in compliance with the license. (Back in the days of PSE 5 adobe worked more on the honor system.)

How to reinstall OS on Macbook Pro that will not boot

I have a mid-2010 Macbook Pro that is stuck on the grey screen with apple logo and progress bar. I'm going to get all my data off of it and then I want to wipe everything off of it and re-install the OS so it is like factory again.
Do i need a disk? What is the simplest way to do this?

Can you inform me on how to format the new hard drive once I receive it?
You will have to connect the new HDD to the MBP via USB (you will need to install the HDD in an enclosure).
Boot into the recovery partition.
Select Disk Utility from the 4 option menu.
Open Disk Utility>Erase, select the new HDD from the left hand column and select Mac OS Extended (Journaled) as the format and click on the erase button.
Exit Disk Utility and select the reinstall OSX option from the 4 option menu.
Install the OSX.
Restart the MBP with the OPTION key down. Select the new HDD icon and boot the MBP.
If successful, install the new HDD into the MBP.
Ciao.
Also, should I even bother re-installing the OS after there is a new hard drive installed? Would it make any difference?
You need an OSX in order for the MBP to function.
Ciao.

I have about 10 computer that will not show they have Windows 7 SP1

I have been upgrading all the Window 7 computers to SP1. I have been running reports and they are saying that some of the computers are not SP1. I looked on the computers and they are showing SP1 but, then I would look in AD at the properties
of the computer and that is showing that SP1 is not installed. This in is only happening in about 10 computers. Does anyone know why this would be happening?
Thanks for your help

Never witness anything as such. Also, how these computers are installed. Try the below query, what it says. Use powershell or something else to find out, are they reporting changed to SP1 or still same.

Ibook that will not boot (apple turns into a circle with....

my ibook was clicking the other night. it has already been through the logic board recall. this appears to be the hard drive. after tech tool pro, the disk utilities, etc., and all of the alternate startup sequences, i now have an apple that turned into a circle with a slash through it (a do not allow type of symbol). i bought a new drive today and after reading many forums today, i am wondering if there is a recall, warranty or if i should send it in the my local store to get fixed or just do it myself tonight. any advice anyone?

Well, since I don't know your level of expertise, it's hard to advise you. Take a look at the online instructions:

Help! Computer turns on but then will not boot up - Please Help!

I have no idea what happened to my Apple. Someone please help me. My powerbook currently is running on no battery (recall victim) and now the entire computer is no longer functioning at all. I installed iTunes 7.0 and then the trouble began. I had to restart the computer, so I did that and then the computer just wont boot up. It goes to the grey screen which shows the Apple symbol and occurs right before my log in then just continues to read. The green light for the battery is function and nothing at all is working. The computer simply will not boot up, I have tried unplugging it for the night and then rebooting it and nothing. Please someone help, what has went wrong?

You mentioned in your other thread that you had trouble with a cpu(0) hardware error trying to use the hardware test disk. Is this the hardware test disk which came with that particular machine? If not, then you need to find the original hardware test disk that came with that machine. If the restore disks that say 12" Powerbook include the words hardware test, use those instead and follow these directions:
http://docs.info.apple.com/article.html?artnum=86287
If you are using the correct hardware test disk and you get a cpu(0) error using it, then the machine has a hardware problem.

Computer will not boot up correctly in any mode.

Hello,
I have a Compaq Presario CQ62 with Windows 7 that will not boot up to my log in screen and it does not matter what mode I put it in..safe..etc. I have tried everything I know to do ...like system recovery in the recovery manager. I have no recovery disk or anything. Any help

That means the internal drive has failed, or there's some other hardware fault. What backups do you have?
