Apple Hardware Test : Use original Tiger Instal disc, or new Leopard disc?

Hi,
I'm STILL trouble shooting my slow iMac. I figure this may point me in the general right direction.
My question is if my computer came with Tiger, and Leopard is now installed, which startup disc should I use?
thanks

Hi:
Try the OS X 10.5 DVD (boot while holding down the "D" key). I have, frankly, never tried to run an "old" hardware test on a "new" computer, but nothing should be harmed by trying.
Incidentally, slow is usually software-related not hardware-related.

Won't boot from Apple Hardware Test or 10.1 Install disc

Disk utility states that I need to boot from a CD and then run Disk Utility to repair my disk. However, neither CD seems to be recognized as a viable startup disk from either holding down the C key or trying to select it as a startup disk in System Prefs.
FYI, I am running 10.6 and trying to boot from a 10.1 disc and an Apple HT disc with SW version 1.2

There is no way any Intel Mac will run with 10.1 -- it was released before there was any Intel support in the OS.
Every Mac model requires a specific version of the Apple Hardware Test to support its hardware. (If yours is the "Late 2008" black MacBook, the Mactracker database says it requires version 3A147.) Somewhere in the fine print of your original grey system disc set, or on any other grey system disc for any model, you will find the version of AHT it contains, if it contains any version. Unless that version is the same as your Mac requires, it won't work.

Apple Hardware Test dvd from Tiger - use in SL?

My Macbook Pro2,2 - 2,33 GHz was shipped with Tiger 10.4.8.
Since then I have installed Leopard, and last night I upgraded from 10.5.8 to SL 10.6 with the retail disk version.
Alas, I no longer have the Leopard disc, but the original Tiger Install disk 1 have the following info printed on it:
Mav OS version 10.4.8
AHT version 3A118
Disk version 1.0
2Z691-5967-A
Now I'm wondering if I can run the AHT from this disc, on the same machine, running SL 10.6 (Build 10A432)?
I have not updatet SL after installation.

Hi
It won't matter what you've installed on the internal drive. Booting from the original disks that came with your hardware will always work as the system being loaded will be the one on the optical disk, not the one on the internal drive. Upgrading the OS does not upgrade the hardware in a way that stops the original OS that shipped with that hardware from working.
The AHT Test is not an OS in the sense you're generally used to.
HTH?

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.

Imac 24 aluminum - apple hardware test using wireless keyboard

The manual that came with my imac describes the steps to run the apple hardware test as follows:
1. disconnect all external devices, except keyboard and mouse
2. restart mac holding the 'd' key
The apple hardware chooser should appear next.
When I do these steps it goes right to my desktop every time. I am running a mac wireless keyboard and mac mighty mouse.
Anyone have an idea how I can get the Apple Hardware Test up?
Thanks.

Hi,
It can take a few minutes for the AHT to appear after booting, D key, etc:
http://support.apple.com/kb/HT1509
Try shutting down your iMac, reboot and THEN do the AHT.
Are you able to boot from the restore disk?
To check the hard disk:
Open Disk Utility, in the Utilities folder in the Applications folder.
Insert your Mac OS X Install disc in your computer’s optical drive or an optical drive connected to your computer, and then restart your computer. When you hear the startup tone, hold down the C key until you see the progress indicator, which looks like a spinning gear.
Follow the onscreen instructions until the Menu Bar appears with the Utilities menu in it, choose Utilities > Disk Utility, click First Aid, and then click the Verify button. If DU reports errors, click Repair. When it's finished, from the Menu Bar, select Utilities/Startup Disk. In the Startup Disk window select MacintoshHD 10.x.x and click Restart.

Can I use my Tiger install disc on more than one computer

I have a Powermac G4 15" and an imac G4 17". The p-mac has Tiger and the Imac has Panther. Can I use the install disc that came with the p-mac to install Tiger on the imac?
Thanks for a great forum!
G4 Mac OS X (10.4.5)

Welcome to Apple Discussions!
PowerMac G4s never were 15". Don't you mean Powerbook G4 15"? If you mean Powerbook G4 15" and it came with Tiger, then the answer is no, as my FAQ explains:
http://www.macmaps.com/upgradefaq.html#SYSTEMSPECIFIC
If you mean a PowerMac G4 with a 15" Apple LCD, it may have come with an older operating system. Use the articles I link to on:
http://www.macmaps.com/macosxnative.html#IDENTIFY
to identify your Mac.
And use
http://docs.info.apple.com/article.html?artnum=25517
to determine which operating system came with that Mac.
If both machines came with pre-Mac OS X 10.4, they can use a Mac OS X 10.4 Family pack if they meet specs for the installation.

Apple Hardware Test using Leopard

One of my MacBok Pro USB ports has failed 24 hours after installing Leopard. It may be a coincidence because it was working fine for a while after the install. I would like to run the AHT but how? With Tiger, you inserted the install disk, rebooted, held down the 'D' key and there it was but this does not work with the Leopard disk. Can anyone help?
Thanks.

I believe somewhere I read that it is on the Leopard installation disk. You hold down a specific key (I don't remember which one unfortunately) when you insert the disk.
Good luck!

Need apple hardware test (lost original DVD)

can anyone help me at all with this? I'm really really stuck. thanks a ton

You will need to call AppleCare....they can issue new DVD's for a small fee

Ran Apple Hardware Test from USB Install Drive on new MBA, Got this error

Last week I got the fully loaded 2010 MBA 13" (2.13ghz/4gb/256gb).
It's just perfect, I have no problems with it.
On a whim, I ran the quick Apple Hardware Test using the included USB install drive (took just a few minutes) and it came up with this:
Alert! Apple Hardware Test has detected an error.
4SNS/1/40000001:IDOR-0.040

Any ideas on what that means? Hopefully it's a false positive. I'm running the extended test right now, which will take more than an hour. Will report back.
Anyone seeing anything from the hardware test?

Apple Hardware Test stops responding

While troubleshooting disk errors on an iMac (27 inch, mid-2010), I tried running the Apple Hardware Test from the Applications Install DVD that came with the computer, by inserting the DVD and holding down the "D" key while rebooting. The test begins normally, then stops working after a few minutes. I let the basic test continue working for more than 30 minutes (twice), but the progress bar hangs at around 95% and screen indicates it has been testing for 3 minutes 20 seconds. I also tried the extended testing and let it go for a couple of hours, but it also appeared to stop responding.
Meanwhile, my iMac starts up normally again, after a few scary instances of the screen going black and immediately shutting down. Disk Utility has stopped returning error messages, and now reports that the "The volume appears to be OK". Is the failure of the Apple Hardware Test a symptom of hard drive or other problems? Should I just let it run overnight and give it more time? For comparison, I tried running AHT (basic and extended) on a MacBook Pro, and both finished normally with no problems.
I appreciate any insights you can share!
iMac (27-inch, Mid 2010)
OS X Yosemite 10.10.2

The original NVIDIA GeForce 8600M GT is able to take even 512 MB and do HCDP. Apple doesn't support this because they look for the mass of normal consumers and not for professionals. Than they would have used a Nvidia Qudro NVS 320M.
Does any one tried "DirectX 10" and "PureVideo HD" on a booted Windows system on the new MBP? (here a link but in German:

and one in English:

I fear that Apple lost the orientation what is possible on a laptop today.
What are your opinions?

Apple Hardware Test (MacPro) result codes

Hello, My MacPro has been doing the wierdest things like freezing up, although the mouse will move. Freezes while monitors are sleeping. Freezes when I move mouse towards dock. Freezes for no apparent reason ... all updates have been performed.
Bright idea tonight, I decided to run the Apple Hardware Test provided on my install disks ... I got an error code "4SNS/1/40000001:VMBS". No idea what it is or means and have searched high and low on the internet for result codes.
Does anyone know what this means?
I have been supicious of my ATi Radeon X1900 XT for some time as there have been artifacts and odd colour shifts and graphic anomalies.
Thanks for your help, all is appreciated.

apple hasn't released a key to the public as to what the hardware codes mean. you really need to take it in for diagnosis.

What is the difference between Apple Diagnostic test and Apple hardware test?

I've just been wondering if one is better than the other? My mac shipped with apple hardware test, and I'm curious if the newer Apple Diagnostics is better

Apple Diagnostics is better, but no Mac model can use both it and the Apple Hardware Test.

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:

Can Apple Hardware Test disk work when a hard drive has no OS installed yet

I removed a bad original hard drive from a PowerBook G4 12" aluminum notebook. It made clicking sounds as it ran, and would not boot. I replaced it with a 320GB Western Digital HD. I also upgraded the original 512KB memory with 1GB.
Before removing the bad hard drive, I was able to boot just beyond the language selection dialog from a full installation CD (Mac OS X v10.2) while holding the "C" key during power on, but could not install it, of course, on the bad hard drive.
Now with new hard drive replacement in the PowerBook (formatted via fire wire from a MacBook Pro running Snow Leopard) and the upgraded memory, I ran a Disk Utility check via fire wire and found the new hard drive in the PowerBook to be in good working order and ready for an OS installation. However I can no longer boot the PowerBook G4 with the full installation CD in the customary manner, getting instead the flashing question mark over the finder folder icon.
I decided to see if there might be some other problem by using a PowerBook G4 Apple Hardware Test disk. Upon booting from the test disk, I get a message that declares the disk will not work with the PowerBook G4 machine.
What's up?

There's more to my original question than whats on the face of it. Please read more about this below. However, I will still wish to know if an AHT, say an original one if that's important, will do it's thing when no OS is installed.
Pretty sure that I'm NOT using either disk or sets of disks that came with this G4 PB. Included among what I do have are 6 grey disks:
__PB G4 Software Restore 1
__PB G4 Software Restore 2
__PB G4 Software Restore 3
__PB G4 Mac OS 9 Install v9.2.2
__PB G4 Mac OS X Install v10.1.4
__PB G4 Applications
And 2 Jaguar full install DVDs:
__Mac OS X v10.2 Install Disc 1
__Mac OS X v10.2 Install Disc 2
I was hoping to be able to find something useful among these disks - if not in a strait forward manner, them by some manner of hacking.
I know how to use my MacBook Pro create a disk image that will house any number of these DVDs. My thought is to create something that can be cloned to the PB G4 via fire wire. I just need to be sure how to daisy chain multiple DVDs in terminal mode, if more than one DVD is required in the cloning process.
I have placed an order for Leopard 10.5 - full installation DVD direct from Apple.
Once received, I will have 14 days to return it unopened. So, I want to be sure this PB G4 is operable before I break the seal on the Leopard package.
Therefore it's not so important that I clone everything from the original installation - just enough to see that the PB G4 boots and runs in Finder. If I can achieve that much, I will advance with Leopard 10.5 when it arrives.
My *PROCESSOR SPEED* is 1.33GHz
Other original specs:
L2 Cache 512 KB
Memory 512 MB
Bus Speed 167 MHz
Boot ROMV 4.8.3f1
Memory Slot 256 MB DDR-SDRAM
