Need Apple Hardware Test Software For Sept 2006 iMac

I am aware it came with the original installation from 4 years ago. But the original installation is not available. Is this available and be downloaded from somewhere else?

No you cannot download the AHT however you can call Apple and they can replace the installation disc for a nominal fee. That way you will have both it and the AHT for future use. Getting a replacement disc is wise because sooner or later you may need it if you plan to sell the machine or need to re-install the OS.

Apple Hardware Test software for late '07 Macbook?

Where do I get the Apple Hardware Test software for a late '07 Macbook? Original disk is long lost and it doesn't appear Apple has this up for download.
The battery is not taking any charge, totally dead after 772 cycles. But don't know if its the battery or the Macbook's internal battery charging hardware.

Using How to identify MacBook models your Macbook is a Macbook 3,1. At this link https://github.com/upekkha/AppleHardwareTest click on Macbook3,1 link which will download the AHT software. Here is the direct link - MacBook3,1 Mac-F22788C8.

What model PowerMac do you have? The AHT is on the Install/Restore disc that came with your Mac.

Separate Apple Hardware Test DVD for MacBook Pro original??

Hey Folks, I'm trying to verify whether or not the MacBook Pro came with the Apple Hardware Test as a separate DVD disk. The "MacBook Pro" Install disk references it but I can't seem to find the software on that DVD. Any guesses out there would be appreciated. I'm about to perform an upgrade for Tiger to Leopard and wnat to give my laptop the "hairy eyeball" before I begin.
Many Thanks,
Peter

Insert the DVD and start up the computer with the D key held down. The Hardware Test is on a separate area of the DVD and isn't normally accessible.

Finding Apple Hardware Test or Customer Support Phone Number

I bought a used g5 from eBay and need to get an Apple Hardware Test CD to test out the hardware. (I've been having kernel panics)
I have been searching for about 30 min for a way to get the Apple Hardware test CD for the g5 or a customer service phone number.
Can anyone point me in the right direction?
Thank you.

Thanks for the help DS...
I called Apple and they are sending me disk 1 of the original install disk that should have AHT on it. I asked the rep whether firmware updates have any bearing on the AHT and they said it didn't. We shall see.

Apple Hardware Test: System Configuration not Supported

I wanted to run Apple Hardware Test on a Quad G5. Right after it launched, it gave me a message that my system configuration was not supported (sorry... I don't remember the exact message).
My Quad was shipped with an nVidia 6600 graphics card (before the 7800GT was available). I recently upgraded from that 6600 to a 7800GT. Could that be the issue?
It's possible I was trying to run an old version of AHT. The disk was labeled:
Mac OS version 10.2.7 (G5)
AHT version 2.1
DVD version 1.2
691-4657-A
If I am running the wrong version, I'd order another copy from Apple (lots of posts on how to do that) but I have one concern: one post said that Apple would only ship the original disks, which brings me back to the first question: would an upgraded video card cause AHT to complain that it didn't support the configuration?

It's possible I was trying to run an old version of AHT.
You were. The Apple Hardware Test intended for your G5 is a bit hidden; you need to insert its first original disk and restart with the Option key held down to access it. Once you see it, click on it and push the button with the straight arrow.

Interpreting Apple Hardware Test Codes...How?

Is there a chart or document that will allow me to decode the errors that are produced by the Apple Hardware Test software?
I'll provide the two errors I've seen, but they don't happen all the time. I'd like to know what these mean, but I'd really like to know how I can decode these and future errors myself.
4MHD/2/40000002:0x7ee50490
I'm assuming this one is a hard drive error, but which one? Internal? External USB Drive? How do I tell?
4YDC/2/40000002:0x7eea4890
I'm not sure what this one is.

First of all, thanks for all your and everyone else's help on this!
I had some corruption on my internal hard drive which I was finally able to fix using a combination of tools (Diskwarrior and Speedtools) and a reformat and reload of the OS. I was still having problems, but they did not appear to be disk related. I started wondering if there might be some hardware issues causing the issues that may have led to the disk corruption previously and be causing some more current issues. I had installed Mac OS on an external drive and had been booting from that to run some of the various tools and I was still having problems. Anyway, as I've been unplugging one device at a time and doing testing, it seems that my system has become much more stable since I have left the one external drive with Mac OS on it unplugged.
At this point, I'm guessing my problem is either a failing but intermittent internal hard drive (since it had corruption to begin with), or something about the external drive that my system doesn't like (that made the system unstable even after cleaning up the internal drive). Recent problems could be either or a combination of both.
Anyway, I think this narrows it down pretty good, so I'm just leaving the suspect external unplugged and waiting to see if I have more disk related problems.
Thanks again.

I can"t open the apple hardware test from the applecare support website

i received the applecare training program for my birthday and while exploring the applecare service source website i found a image file of the apple hardware test (AHT) for each model along with a pdf of the service manual and a pdf of the AHT service codes. The problem i'm having is, i cant open the image of the AHT.

After downloading that image, open it and it will show up mounted in your desktop. Then, open Disk Utility (in /Applications/Utilities), right-click your Apple Hardware Test image in the sidebar and burn it to a DVD. Finally, start your computer from the disc, holding the C key, so Apple Hardware Test should start, always that you have the correct version for your computer.
You have Apple Hardware Test in the Applications disc that came with the computer. In that case, hold the D key while your computer is starting

Is there stress testing software for the Mac?

I am looking for a stress-testing program for OSX. Something that would press a computer to it's limits and make it crash faster, if it's supposed to crash intermittently. Can anyone suggest such a program for the Macintosh?
iMac G4 Mac OS X (10.4.6)

Hi, T.M.
If you're looking to troubleshoot an intermittent problem that may be hardware-related, See my "Apple Hardware Test" FAQ for comprehensive advice on using the Apple Hardware Test in troubleshooting, including running the test in Loop Mode.
There is also Xbench, a performance benchmarking tool.
More details as to what prompts your question might help.
Good luck!

Hardware test software

I am looking to see if I can download the Apple Hardware Test software, if I do not have the original disk?

Yes, that's what I thought as well. However, I have an iMac I bought last early fall, Lion already installed, and holding down D doesn't work, nor do I have an installation disks. Moreover, when I try the firmware upgrade that's supposed allow booting from the internet, I get a report saying it doesn't work on my system.
Go figure.

IMac intel late 2006, lost DVDs, how to run apple hardware test

Hello, Applers,
I have an iMac intel core 2 duo late 2006. I have upgraded it to snow leopard. From two months ago, it began to show distorted pictues, random lines/pixels/, and regular freezing. But if I boot it into the safe mode, it works well, although there is no sound or webcam. I did a research online and it seems that I should run apple hardware test (AHT) first. But the DVDs came withi this machines have been lost. where can I download this software? I would greatly appreciate your help if any of you who also have this model of machine and would like to lend me your DVDs.
any suggestions are welcome.

You can purchase replacements from AppleCare:
Apple Store Customer Service at 1-800-676-2775 or visit online Help for more information.
To contact product and tech support visit online support site.
There is no way to run the AHT without the discs.
If it works OK in safe mode then you might think about:
Resetting your Mac's PRAM and NVRAM
Intel-based Macs: Resetting the System Management Controller (SMC)
Reinstall Snow Leopard:
Reinstall OS X 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.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

HT201257 Holding down "D" no longer starts Apple Hardware Test! Any idea what's happened and how I fix it? Or do I need to go to the Genius Bar? MacBook Pro with Lion Preinstalled.

I have a MacBook Pro with Lion Preinstalled, so AHT was present on the hard disc and worked when the product was new. One of the first things I did from new was run AHT and it worked fine. But now it doesn't start - instead the machine (eventually) boots into normal OS X.
Holding down "D" no longer starts Apple Hardware Test! Any idea what's happened and how I fix it? Or do I need to go to the Genius Bar?
Software Mac OS X Lion 10.7.3 (11D50b), if it makes any difference.
Any ideas?

Thanks. However, even with an internet connection that doesn't work for me - the machine just (after an extended delay) boots normally. It doesn't download.
Option-D works for an Internet-based AHT. However that only works with an internet connection. It doesn't seem to download it and install it - it needs internet every time.
Any idea how my local copy of AHT disappeared? I haven't repartitioned the drive or knowingly deleted anything. And how do I reinstate it (because if you need AHT your hardware problems may preclude internet access!)?

COOL FEATURE-Apple Hardware Test built-in. No disc needed!

It's a MacBook Late 2007... it would be interesting to see what other models have this feature.
Start the Mac
hold the D key
do NOT put in your installer disc
it starts up Apple Hardware Test (AHT) in like 5 seconds. No disc needed. VERY COOL
(unfortunately, it seems to have been disabled after I did the Keyboard Firmware Update) -- 2 units, same issue.
Is there a way to get this feature working again?
What other models have (had) this feature?

Well, I've tried some experiments:
1) Removed the hard disk from the MacBook, and tried starting up while holding down the D key. Question mark icon. So apparently the AHT is not in ROM, but ensconced somewhere invisibly on the HD.
2) Put the HD back in, started the MacBook from a standard, late-2007 retail 10.5.1 Install DVD (not the Install/Restore DVD that came with it). No AHT of course. And when it started up, the backlight went dark. Shining a lamp on the screen and looking from an angle, I was able to see enough to erase the HD. And tried starting again with the D pressed. Question mark icon. So apparently the AHT is not in a special HD partition that persists even when the HD is erased.
3) Installed 10.5.1 on the MacBook HD using the standard 10.5 Install DVD (not the Install/Restore DVD that came with it); once again, running the MacBook from that DVD turned the display backlight off. Then started the MacBook with the D key pressed. Question mark icon. So the standard, retail 10.5 Installer doesn't install the AHT.
4) Started the MacBook from its own Install/Restore DVD, and restored the factory HD setup. When setup was finished, shut down and started again pressing the D key. Apple Hardware Test (v.3A143) appeared.
Conclusion: Apple Hardware Test is on the hard disk, not in ROM, installed as part of the software specific to this model. If the disk is erased and System software is installed from a generic 10.5 DVD - for instance, because the original Install/Restore DVDs have been lost - AHT will not be installed. So the instructions in the manual apply only so long as the original disk setup (or a restoration of same using the original DVDs) remains. Otherwise the original Install Disc #1 will be required to run Apple Hardware Test.
