HT4904 Apple Hardware Test or not?

Tried to open Apple Hardware Test on my MBP Pro 13", but pressing the D-key while starting the MBP did not work.
Turned to "Computers that can be upgraded to use Lion Internet Recovery" where the latest MBP 13" is early 2011.*
My MBP 13" is late 2011 (recently upgraded to OSX 10.8.1).
What can I do to use the test?
*Download and install an updated EFI Firmware ROM for these computers to use the OS X Internet Recovery feature:
MacBook Pro (13-inch, Early 2011)

Ok, I tried it but the disc is damaged and can not be read.
(Strange because the disc have never been used. I called Apple about this and they
said that they do not produce CD/DVDs anymore with AHT.)
Which number did you call?
You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.
If you're not in the US, you may need to go through the regional Apple Store that serves your location to find the contact number. Here's a list of links to all of those - http://store.apple.com/Catalog/US/Images/intlstoreroutingpage.html Another resource: International Support Phone #s.

Apple hardware test does not support this machine, iMac 27" mid 2010

Hi, I have a mid 2010 iMac 27inch with OSX Maverics updated to the very latest version.
I need to hardware test my mac but I am finding it impossible. If I press D at bootup, nothing.
Option D, loads hardware test, but it comes back saying:
"Apple hardware test does not support this machine."
I don't have the original install disk for the mac and it has been updated several times online to the latest version. What am I supposed to do in this instance?

That Mac model requires the original system disk to run AHT. You can call Apple at 1-800-MYAPPLE, and ask for an operating system specialist. Then you can request replacement system disks for your computer. The cost us usually under US$20.
Have your serial number at hand; it is required for the techs to find the correct disk set for your model.

Ugh/ kernal panics / apple hardware test will not boot / help

so my first thought is to replace all my memory and I even have some coming via OWC -- but it seems silly just to replace memory on a hunch and randomly. So I run rember and get an all cler on all my memory. Can this really be soo? So I think - try the Apple Hardware Test.
I hold down c key as 'puter is booting and I get command line screen that says
"invalid memory ascess at %srr0:ae0c0108
%srr1: 0c01086F
bad bus info crc-16"
than it tells me to type in mac-boot to boot --but it will not boot - the next screen just says command line ok
what should I do next
this machine has been acting up for over 6 months and its driving me nuts -- I bought the memory as a "quick fix" but now I am starting to have my doubts. It would be cool to know before I decide to install it so I can return it for my $ if my hunch is wrong --
help! and thanks!

I can give you some general advice about buying memory:
The question then becomes what if memtest passes it all... I couldn't complete the cloning of about 220 GB of files from one drive to another with the original MacWarehouse chips in place, but could when they were removed.
I have had quite a bit of experience testing memory, most of it grey market stuff that I salvage from trash cans and such like place. I have found some memory that worked perfectly and never gave me any problems. I have found some memory that gave me kernel panics. I have found some memory that are somewheres in between: they seem fine at first, and then when you start to run lots of apps or copy large files that's when the problems shows up, and the problems are subtle -- once in a while a task would randomly crash, but restarting the task would make it OK, etc., etc.
I've had a PC133 stick that repeatedly tested and passed on memtest until the 4th pass, then an error showed. After the error showed, there were lots of errors.
For my own use, I do not use any memory that fails memtest at all, since I am swimming in memory anyway. I usually test them overnight. Certainly when buying new memory I expect them not to fail memtest when run overnight (usually about 6-7 passes).
I'll use memory that fail occasionally in client stations that are not function critical, but my experience has been once you get some error in a memory chip, it gets worse with time.
I want to avoid if possible having the machine down for hours at a time to run memtest in Single User mode as it's serving up genealogy databases on 4 different domains, as well as static pages on 8 other domains as well as being my every day work-a-Mac.
If you're serious about hosting those domains, I suggest you buy a Mac Mini for your clientstation and let the server be the server.
sending CL3 chips maybe the Apple Hardware Test is expecting to see CL2.5 which is what the 3 chips I have to do work are.
CL3-PC3200 chips can pinch hit for CL2.5-PC2700 chips in some limited circumstances, but they were sending you CL3-PC2700 chips in place of CL2.5-PC2700 chips. I smell herring.
or are they really not the chips the label says they are?
Chips are sometimes mislabeled, due to operator error.

Apple Hardware Test (Extended) not progressing

After upgrading my white MacBook (13-inch, mid 2010) from Snow Leopard to Lion, i was getting Kernel Panics, maximum of 5 min after startup. So i decided to downgrade back to Snow Leopard.
I erased my hard disk, tried to install SL from the DVD that came with the MacBook, i got a Kernel Panic. I tried it for 6 times, all with the same result.
I made the Apple Hardware Test, it passed.
Now i'm trying the Apple Harware Test (Extended), it's been almost 6hrs and here's the status:
Testing Memory
No error messages
Pass Number: 1
Time: stuck on 2hr 15min 49sec
Progress Bar: about 13%
However the mouse is still responsive. Is it normal for the test to take this long.
Thanks
PS: i tried the option-commant P R before running this test, and i dont have any peripheral connected

I have had endless issues with kernel panics since Lion. Rolling back to SL won't save you, because the last couple of updates to SL added in the cause of the panics:
Some combination of multitouch trackpad drivers and the graphics card drivers.
So, what I've done, and it seems to work better ( I can use this POS laptop for more than an hour now) is:
System prefs: turn off all the multouch stuff. All the gestures. Off.
Also, battery life is low because this os constantly writes to the hard drive and uses the network card. If you happen to push the system while you hear the fans spin up as it receives a push notification ...panic.
Spotlight has big problems with Lion. I stopped it from indexing almost everything, installed quicksilver, then turned off indexing on the drive. I uninstall flash unless I need it also.
kernel panics for me would always feature AppleHWSensor in the panic log.
60% triggered by me using the expose show desktop guesture. However, I assigned that to a keystroke... works fine.
I've lost 3 hard drives to this garbage, ( you can't keep on just turning off modern unix systems, via kernel panic)
Try what I suggested:
No Flash until you need it.
Turn off all the multitouch stuff in trackpad prefs
stop spotlight from indexing your logs, and Caches. Then turn it off.

Apple Hardware Test CD not seen

I need to run the Apple Hardware Test but the computer doesn't see the CD when I start using the C key, or even when I use the Startup Disk System Prefs. I have also tried using an external CD/DVD drive & that doesn't work either. In case the AHT disk is faulty I have downloaded & burned a new test disk. Nothing works. Any ideas?

Since this is the aluminum discussion group, I'll assume you meant to post here about your 1.67Ghz Powerbook. First, there is no Apple hardware test that you can download for it, at least from Apple. You need the original OS X disks that came with the system. If you had Applecare, you can download TechTool Deluxe, which does similar testing.
In order to run the Apple hardware test, reboot while holding the alt/option key down, then you can choose the Apple hardware test, or hold the D key down, which should go right to the test. When I run it, I use the alt/option key. If you have the original OS X disks that came with the system, make sure the one you're using says 'AHT Version x.x' in small print on the gray label. If you put the OS X disk in an external drive, using the alt/option key when you boot should allow you to choose it.

I want to run apple Hardware Test but can't find it on any CD's. I bought my iMac in 2009. I think it had 10.4 installed. It's not on my installation disk. Where can I find it?

I want to run Apple Hardware Text but can't find it on any CD's. I bought my iMac in 2009. It came with 10.4. Apple Hardware Test is not on the installation disk. Should I have it? Where can I find it? I"m now running 10.7.4.

The disc plainly state:
To use the AHT, hold down the D key as the computer starts up.
Works here. However, there was an issue with installing Lion that screwed this process up.
Mount disc 2, run this command in the Terminal app, OPTION-click & hold Finder's Dock icon, and select RELAUNCH:
defaults write com.apple.finder AppleShowAllFiles 1
That unhides all hidden files/folders.
Now, drill down to /"Applications Install\ Disc"/System/Library/CoreServices/ and drag the .diagnostics folder into your Lion boot volume's /System/Library/CoreServices/ folder. That might require you to authenticate to copy the folder into the CoreServices subfolder.
Run this command to hide the normally hidden files/folders and RELAUNCH the Finder again.
defaults write com.apple.finder AppleShowAllFiles 0
This should allow the machine to boot into AHT when restarting and holding down the D key.
If that doesn't do the trick, run this command in the Terminal app:
sudo chown -R root:wheel /System/Library/CoreServices/.diagnostics
At the Password: prompt, carefully type in your admin password, since nothing shows up on the screen, and hit the return key. Then, try another restart, holding down the D key.

Can't get Apple Hardware Test to work

So I'm trying to run the Apple Hardware Test. I start the computer up and hold "D". It boots into OS X like a normal startup. So, I plug in the Ethernet and hold option-D to do the AHT from the Internet. It tells me "Apple Hardware Test does not support this machine".
So, I try to install the "iMac EFI Update 1.8" from http://support.apple.com/kb/DL1493 (which is for my iMac model, which is a iMac (Mid 2010)), but it says "This software is not supported on your system." I also tried the later version, v1.9, from http://support.apple.com/kb/DL1498 but it isn't for my iMac and so I get the same error.
So now I'm stuck. What should I do now?

Thanks that was it. It says AHT on the disk itself. I successfully ran it, and it found no problems ("No trouble found.") I ran the basic test only because I have 16 GB RAM, and so I imagine it would take a long time to run the extended—probably at least two hours? And I don't know what more that would find that the basic wouldn't?

Apple Hardware Test

I just upgraded the ram in my new 2011 iMac and I want to run Apple Hardware Test. Since Apple no longer supplied a DVD with this bootable app I was wondering how I can launch the App. I tried apple's online doc and held the "d" key down to try to boot it from the internet but eventually the OS just launches instead. I then read that you are suppose to pess Command + D, same thing its a gray screen for a while but then eventually launches OSX. I even tried a bootable DVD of Snow Lepard and its not compatable. Please help. Id like to be able to run the hardware test.

Hello
Instructions tu use AHT from help menu
try use an ethernet cable , turn off airport ,restart your computer while holding down both the Option and “D” keys
Use Apple Hardware Test
Open the Help Viewer’s Action pop-up menu (looks like a gear) and choose Print to print these instructions.
Disconnect all external devices except the keyboard, mouse, display, and speakers. If you have an Ethernet cable or external DVD drive, disconnect them.
Restart your computer, holding down the “D” key while the computer restarts.After your computer restarts, you should see the Apple Hardware Test chooser screen. If you don’t, Apple Hardware Test may not be available on your computer. You may be able to start Apple Hardware Test from the Internet. Reconnect your computer to the network, and then restart your computer while holding down both the Option and “D” keys.
When the Apple Hardware Test chooser screen appears, select the language you want to use, and then press the Return key or click the right arrow button.

-3403D error when attempting Apple Hardware Test

Hi everyone,
I want to perform an Apple Hardware Test. I restarted, pressed option+D, and a globe appeared. After a minute, however, the following text appeared:
Apple.com/support
-3403D

Your Macbook Pro came with OS X 10.6.x and to run Apple Hardware Test you can use bundled with your Macbook Pro Application Disc:
Using Apple Hardware Test - Apple Support
Your Macbook Pro probably was upgraded to use OS X Internet Recovery as some of the Mac which came with 10.6.x did have that option. It seems like, some of the models might have problem to access Internet AHT:
Computers that can be upgraded to use OS X Internet Recovery - Apple Support
About the "Apple Hardware Test does not support this machine" message - Apple Support
Not sure what error -340D means but if you haven't tried yet, i would suggest to turn OFF your router and after 2-3 mins turn ON again. Try with different network as very often issues with starting Mac in Internet Recovery are caused by network settings. This could be the same issue...

Apple hardware test for snow leopard

I've tried booting from the snow leopard installation disk i have, i've tried holding down both D and Command+D, and neither of these key combinations work. My macbook will just boot like normal. And it's not an optical drive issue because i can hold C and get disk utility. So is the AHT even on this disk?
Is there another way of testing the hardware or some kind of freeware i can get?

If your Mac came with DVDs, Apple Hardware Test comes in one of these DVDs. See > http://support.apple.com/kb/ht1509 Insert the DVD that contains Apple Hardware Test, and hold the D key while your MacBook is starting. Make sure your Mac is plugged in and run an extended test.
Apple Hardware Test is not included in the retail Mac OS X Snow Leopard disc because there are different versions for each computer

Apple hardware test - how long?

I have tried to run the Apple hardware test with my iBook G4. The reason for this test is that my ethernet port has stopped working.
I have tried all online tips I can find with no result. The only things I haven´t tried is the hardware test and a complete reinstall of the OS X
(in case the ethernet problem is software related)
The hardware test works great until the test of the logic board. 33 seconds after pushing the start button, the fan speeds up for a second or two
and then slows down and stops. The progress bar stops and there are no sounds from the ibook.
It looks like the test have frozen, although it could be working veeeery slowly.
After 37 hours I was feed up so I pushed the stop button. No reaction.
Other two - button combinations doesn´t work. The only thing that stops the test is holding down the power button.
The iBook boots nicely from the hard disc and from the installation CD.
So my question is:
How long should the hardware test normally take?
Any other ideas?
Timmy

The Apple Hardware Test does not actually check the Ethernet port directly. It will, however, check the logic board that the Ethernet port is build-in to. Usually the longest part of the test is RAM. If you're not even getting as far as the RAM tests, then there could be something wrong with your hardware that the AHT can't overcome. But, in any case, it should never take more than an about an hour to run.
Perhaps it's time to consider getting an AirPort card for the iBook and using wireless Internet at home?

Apple Hardware Test-Where?

I am a new owner of an iMac Core Duo.
In this General iMac (Core Duo) forum, I have seen a few posts that mention Running A.H.T.
When I've bought previous Apple Computer models, they all came with a CD specific to that machine called "Apple Hardware Test". (Not the AppleCare Test CD, which is TechTool Deluxe).
Although my new iMac shipped with the restoration DVD's, I cannot find any disc that has AHT on it.
Should I have one? Is the Test, on one of the bootable DVD's, and I'm not seeing it?
I'd like to know how others are using A.H.T. with their Core Duo, and where they found it.
iMac Core Duo Mac OS X (10.4.7) 20", 2 Ghz, 250 HD, 1 GB RAM, 265 MB VRAM,

Hi Chris,
Take a close look at the 2 DVD's that came with your iMac
On the one labelled "iMac Mac OS X Install Disc 1" you will notice on the right hand side of the Disc it states "To use Apple Hardware Test hold down the D key as the computer starts up."
Alternatively, with the Disc inserted hold down the Option(alt) as the iMac starts up; this will take you to the Startup Manager screen where you will be able to select AHT as the startup volume.

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:

Files/Folders Sticking to Mouse Pointer - Not Releasing (Reset PRAM & Apple Hardware Test Fail to Run)

I've been having two issues with my Late 2008 MacBook Pro 15-inch - Running OS X 10.8.5 (Mountain Lion). Unable to Reset the PRAM and Run Apple Hardware Test (AHT).
On a random basis - File/Folder icons are Sticking to the Mouse Pointer - Not Releasing. I've done everything from trashing finder preferences, making sure Universal Access preferences are off, Restoring Defaults in the Energy Saver System Preferences, Resetting the System SMC. Another post mentioned that this is being caused by the Graphics Driver not working correctly - and mentioned to put the MBP to sleep, then wake it up, and the files/folders are no longer sticking to the mouse pointer. This works for me and released the sticking items in the Finder.
OK, Good this is a simple fix, BUT, what is really causing this issue, and how may it be fixed or repaired?
I also tried to Reset the PRAM and Run the Apple Hardware test (AHT), and these both fail to run on my MacBook Pro with OS X 10.8.5.
1) Resetting the PRAM:
Shut down the MBP, press the power button, and hold down at the same time <option><command>-P-R. The Reset PRAM process never starts up, but rather I receive the Padlock/Password Login which logs me into the Restore System Utilities. I'm unable to Reset the PRAM.
2) Apple Hardware Test (AHT):
Shut down the MBP, press the power button, and hold down the "D" key, the system boots up as normal and does not enter the AHT.
The File/Folder Finder sticking to the mouse pointer issue is very annoying. Does anyone have a solution to resolve this issue?
- Cheers

HI Barbara,
It sounds like the hard drive is failing or has failed. Boot from your Mac install disc and if you can run Disk Utility in case the startup disk needs repairs.
Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
*(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)*
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. *Make sure there is always 10% to 15% free disk space*
If you cannot boot from your install disc, try booting in Safe Mode
What is Safe Mode

Apple Hardware Test (AHT) invoked at startup with 'ALT-D' not 'D'

Although several reasonnaably reliable sources (including such page as http://support.apple.com/kb/HT1533 ) mention that pressing 'D' at startup will invoke the Apple Hardware Test startup option, at leats on my Macbook Pro 2011 with OSX Lion, EFI 2.8 it is really 'ALT-D' that invokes AHT not 'D'. Pressing the 'D' at startup simply seems to hangs bootup until I release the key.
