Apple Hardware Test doesn't happen???

Hello,
My Mac is quite unwell and I believe the hard drive is failing.
I have just performed my third erase and reinstall since Friday.
Only this morning I discovered the Apple Hardware Test.
I've erased the hard drive so the Apple Hardware Test had been deleted.
I'm supposed to be able to do by holding down "D" and starting up with the Install Disc in, however, the computer just boots as normal.
Any ideas how to get the AHT?
Cheers.

You can setup iCloud eMail even in 10.4.11, or 10.5.8...
Do not delete the old account yet. sign up for an iCloud account if you haven't.
I understand .mac mail will still come through. Do not delete the old account yet.
You cannot use .mac or MobileMe as type of Account, you have to choose IMAP when setting up, otherwise Mail is hard coded to change imap.mail.me.com to mail.me.com & smtp.mail.me.com to smtp.me.com, no matter what you try to enter.
iCloud Mail setup, do not choose .mac or MobileMe as type, but choose IMAP...
On second step where it asks "Description", it has to be a unique name, but you can still use your email address.
IMAP (Incoming Mail Server) information:
• Server name: imap.mail.me.com
• SSL Required: Yes
• Port: 993
• Username: [email protected] (use your @me.com address from your iCloud account)
• Password: Your iCloud password
SMTP (outgoing mail server) information:
• Server name: smtp.mail.me.com

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!)?

Can't perform Apple Hardware Test of any kind

I can't perform an Apple Hardware Test – on a late 2008 MBP – from original software disk, because my superdrive (matshita dvd-ram uj-868) has long been broke.
Whenever I insert any kind of disk, it doesn't even read neither the machine recongnizes it and it's really a **** of a bum to eject it (when lucky I manage to remove it with force-eject).
Anyway, these are the sollutions that Apple tells in order to perform the AHT
http://support.apple.com/kb/PH11342
If you have a new Mac (…) I don't
If your Mac has OS X v10.8.3 or earlier (…) I'm running OS X v10.8.4
If you updated your Mac to OS X v10.8.4 or later, use the system software disc or USB flash drive that came with your Mac. Well, obvious reasons…
So, what can I do?!
P.S.: I would like to run the Apple Hardware Test:
To know what happened to my SuperDrive.
For a long time it keeps with high temperatures (at least 70°C 158°F), causing the loud fans to pump up. Even with low %CPU usage (already have SMC fan control)
To have an overview of how is my machine doing.
Thank you!

I've already tried and it didn't work because my MBP can't' be upgraded to OS X internet recovery (using option+D)…

Problems running Apple Hardware Test

I'm trying to run the Apple Hardware Test, but it never seems to start. I've tried holding down the C and option keys on restart, but all that happens is that the disk is ejected, and when I push it back in the computer restarts as normal. Is there anything else I can try?
Thanks

Thanks for the for the suggestion, but holding down D doesn't work either. As the computer starts up, the disk ejects (whether there's a disc in there or not), no matter what I'm holding down. And when I push it back in there's a lot of whirring, indicating the disk is spinning, but the computer starts up as normal; no hardware test. Any ideas what's wrong?
Thanks

Will Apple Hardware Test definitely detect RAM errors?

Hello,
Been having various problems with Leopard/MacBook. Someone suggested running Apple Hardware Test, which I did, in extended + looping mode all night (it cycled 6 times). The test turned up nothing. Can I take this to mean that whatever problems I am having are definitely software related? I am not familiar with the AHT, don't know exactly what it does, nor how I can interpret a "clean" result...
Many thanks for any advice/tips.

No indeed (just "Colin" is fine...)
My problems have mostly been documented by other people, and I have just been monitoring the discussions on these issues.
Specifically (at the risk of getting off-topic):
1) inconsistent shared server behaviour: I have 3 other macs at home - an iBook and a G4 MiniMac running Tiger, and a G4 tower, also running Leopard - and most of the time, the tower doesn't show up at all, but I can connect to it via CMD-K, the MiniMac shows up in the sidebar, but won't let me connect, and the iBook, when it is running, behaves normally. Oh, screen sharing doesn't work either: it tries connect but hangs (except for the iBook, which works). I could connect to all four quite normally after upgrading to 10.5.0, using the sidebar icons. Everything worked fine until sometime after the 10.5.1 update, when suddenly everything went pear-shaped. Nothing has changed in the configs of the other machines, and the iBook and the MiniMac are identical in terms of software config (but behave differently as regards this problem?!?)
Closing Airport and reopening it makes the icons reappear in the sidebar (all of them, G4 tower included), as does relaunching the Finder, but doesn't change the behaviour: I still can't connect. When I try to use the sidebar icon for the tower, it disappears (the icon...)
As far as I can tell, trying to operate shares from the G4 tower works as Apple intended (although I admit I have not exhaustively tested every option, as I don't have unlimited time...)
2) Lost my printer connections, both at work and at home. I managed to reestablish them at work, but I tried so many things that finally I'm not sure what actually worked. No dice at home (shared printer on the MiniMac... same problem as (1) I guess.)
3) the dreaded Keynote spontaneous reboot problem (I placed a reply about that last night here:
http://discussions.apple.com/message.jspa?messageID=6630702#6630702
4) diverse weird things, like
4a)iCal which had doubled all my events the last time I opened it. I had to manually delete one copy of every event I had entered, whereas I made these entries several weeks ago, and had consulted them many times... I'm thinking this is perhaps a result of the brutal reboots caused by (3)? Having deleted all the doubles, iCal seems to be behaving normally again.
4b)screen resolutions on my slave screen suddenly failing to select properly. I move my MacBook between two different external monitors, one at work, one at home, and their resolutions are different. Initially the MacBook had no trouble detecting and correctly setting the resolutions for the two screens, then suddenly my home screen went weird on me, and required a manual reset. Again, this was a once-off, and does not seem to be repeating (yet).
4c)sluggish performance with some apps that are normally quite snappy, like Firefox, which seems to hang a lot loading pages, Keynote (saving is often painfully slow), and indeed, trying to copy a 250Mb file from the tower to the MacBook via Airport (having connected using CMD-K) said it was going to take 33 hrs, which I thought was a bit rich...
4d) hot-swapping a usb pin for a keyboard+optical mouse receiver from the tower to the MacBook sometimes causes something inexplicable to happen to the MacBook's keyboard: both the Caps and the NumLock LEDs come on, and the keyboard has jumped into some config other than what it is normally in (French). I have not been able to determine what the keyboard actually thinks it is when this occurs (3 times now). The command keys (ctrl, alt, cmd) do not appear to work at all. Rebooting corrects it.
All up, pretty irritating, and a huge time waster, as you can well imagine. I stuck a bit of a rant on the discussions the other day in a moment of intense frustration, which got zapped by the moderators (probably not unreasonably!), but not before someone replied suggesting that it might be bad RAM, hence my questions here.

Apple Hardware Test Problem!!!

I've been having problems with my 4 month old G5 and so I ran the AHT.First I ran the extensive test and the whole thing froze after 3 minutes.I turned the computer off and on again.It started up like nothing hapened.I restarted,ran the short test and the same thing happened at 1 min 55sec of the test. The computer seems to be running fine but when it's frozen up I'm afraid I have two red led's on the front (I take that's the logic board?) it seems to be LED#1 and LED#3.
I wouldn't bother anyone but the closes reliable Apple Certfied Service Provider is 230 kilometers away...seriously.
Thanx a bunch!

Thank you guys so much! I just want to clarify this
one more time (I am new the whole Mac culure)
My AHT corresponds to Mac OS 10.4.4 making it
useless, right? I did read quite a few posts about
outdated AHT but I didn't get if there was a way to
get a newer version.
A new version of OSX will not affect the hardware test because the hardware test doesn't use the operating system. It will run even if the hard drive is empty. It is possible that a firmware update might require a new version hardware test. If the hardware test is failing, remove any non-Apple hardware (RAM, PCI boards, etc.), unplug all FireWire and USB devices (except mouse and keyboard), and try the test again. If it still fails, call Apple. If you need a newer version of the hardware test, they will let you now.

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 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.

I have a latest 2.7 EFI update but i still don't have the ATH(Apple Hardware Test) software! why is that so? do we have it on mountain lion?

So as u know the question
ill tell u the steps to try them out(no harm will be caused to u or ur com)
During restart-up press the D button before the gray screen appears and hold it for about a minute until u see a 4 or 6 bit image of old mac icon appear and then it loads u go select any language and click hardware test full and then tell me if it DOES HAPPEN ON OS X 10.8(mountain lion).
Thnx apple and u guys!

To use Internet Apple Hardware Test, start up your Mac and hold down both the option and D keys on your keyboard.

Cannot start-up to the Apple Hardware Test — MacBook Pro & Lion

Whenever I try holding the D key before and throughout all of the start-up process, it simply makes the grey screen appear for longer, and slow the whole process... but never beings the Apple Hardware Test.
I'm following Apple's official instructions:
To start up your computer in Apple Hardware Test:
Press the power button to turn on your computer.
Press and hold the D key before the gray startup screen appears. An Internet-enabled connection via Ethernet or Wi-Fi is required to use this feature.
Note: Some Macintosh computers that shipped with OS X Lion support the use of Apple Hardware Test over the Internet. These computers will start up to an Internet-based version of AHT if the hard drive does not contain AHT.
Why doesn't it work?
My MBP was shipped as follows:
For Apple computers that shipped with Mac OS X v10.5.5 to 10.6.7, Apple Hardware Test is located on the Applications Install Disc 2 and should be included with your computer.
But I have upgraded to Lion! Do I need the disk still? If so, why am I to lumber around a disk from a previous OS... good that I didn't throw it out!

I'm trying to find the answer to a similiar question. Here's my thread.

Apple Hardware Test (AHT) Hard Drive Full Read Fail But SMART Status OK

I have a Mac mini Server from Mid 2010 running Snow Leopard Server.
Ocassionally, it'll freeze up with the spinning beachball wheel for a few minutes. This usually happens when opening an app or performing an app function from the menu bar. It's a pretty clean system—there are not many apps installed.
I suspect it's a hadrware issue. I ran Disk Utility's Permission and Disk Repair. All good. SMART Status is verified. So I ran the Apple Hardware Test. Everything passes except for the Hard Drive's "Full Read"—it fails because "Reading took longer than the average time". The Hard Drive "Short .. test" and "Check SMART Status" pass.
Does anyone have an idea of what's going on here? Is the hard drive the issue? I don't understand how there can be a read issue (or hard drive issue), when the SMART Status is verfied.

S.M.A.R.T isn't perfect. Neither is AHT for that matter, but if it is reporting that reading is taking longer than it should then an impending failure is likely. The occasional "wait cursor" appearance supports that diagnosis.
Consider yourself fortunate in that you still have the ability to back up anything important, and you can plan a convenient time for its replacement.

Error Code After Running Apple Hardware Test

I ran apple hardware test (I'm having problems where my computer freezes for like 10 seconds with the mouse being movable... but it happens very frequently. like once a minute. it's SOOO ANNOYING)
this is the error i got after running apple hardware test:
(it came out as a Mass Storage error... which is Hard Disk i guess)
**ERROR*CODE***ERROR*CODE**
2STF/8/3: S-ATA Bus 0-Master
**ERROR*CODE***ERROR*CODE**
Does anyone know what I can do to fix it. Apple Hardware Test only allows me to find the error and then restart or shut down... which is useless cause what is the error code supposed to mean. I've only got Apple 1 yr repair support left... so I cant call up Apple or anything. Does anyone know anything about this and what I could do to fix it!?
I know about this: http://www.apple.com/support/imac/repairextensionprogram/
I might go to the apple store, but I dont wanna make a trip out there for nothing.
Does anyone know what I can do or should I just take it to the apple store.

Actually, i just spent like 1 hr working with disk utility using the os x install disk and i think it finally worked. im so happy for myself! yay... i wouldnt accept no for an answer. Disk utility kept saying "oh first aid failed because it didnt exit right" or something... total garbage response... i kept pressing verify disk and then repair disk and then i did the verify permissions and repair permissions too... didnt really know what i was doing with the permissions... but it finally worked so thats all that mattered! yay... its back to normal!!

Apple Hardware Test problems

Hi All. I have a very weird problem here, as I can't get the Apple Hardware Test to start on my late 2008, 2.66 MBP15 inch model# MC026LL/A (released early 2009 as a quiet upgrade from 2.53). Here's the story:
I opened up my machine as usual one morning, and the optical drive made a very weird noise I never heard before. So I decided to run the Apple Hardware Test (AHT) to see if anything was amiss. Well, I inserted the second install disk, held down the "d" key, and restarted the machine. It began to boot into the hardware test, but just after the AHT screen appears the computer just shut down. This happens every time I try to run the AHT.
I went to an Apple Store while I was on holiday in Brisbane (they don't have one here in Adelaide), and the genius said it was likely a bad optical drive. Well, I returned to Adelaide last week and had the local Apple Authorized store replace the optical drive. Tried to run AHT once again, and the same problem persists. So the original problem wasn't with the optical drive.
I thought maybe I accidentally used the startup disks for my wife's late 2008 15inch, 2.4, MBP (the one actually released in late 2008). I've looked around for the other sets of disks and can't find them. So here's what I'm asking help for: can someone who owns a 15inch MBP 2.66 15-inch (released in early 2009, model# MC026LL/A ) please tell me what the part # is for their set of install disks? It is written on the plastic sleeves of the install disks. And, could this person please tell which version of AHT is written on the disk itself? The set I have (which I think might be my wife's) has AHT version 3A158.
Might this be the problem, or should my computer still be able to run the hardware test using my wife's disks? I know they are both technically late-2008 15inch unibody MBPs, but I think my 2.66 (again, quietly updated and released in early 2009) might require a different AHT version, which would explain my inability to run the test. If not, what might be causing my computer to not run the AHT? I tried reinstalling OS X to no avail.
Thanks for all of your help!

I think I share your skepticism--if your Mac was shipped with the later version of the OS, you should not have been able to do a clean install with discs of an earlier version. It looks like some machines originally shipped with OS X v. 10.5.5 and others with OS X v. 10.5.6. I don't remember just when 10.5.6 came out.
Your two machines are likely very similar in build, and maybe similar enough for the OS to install. It may be that the AHT is specifically designed for the hardware in each machine, and that would be a bit different.
As someone else said in another thread, there ought to be a tutorial on how to keep track of the original install discs since they are always getting lost. Maybe a secure note in the keychain or something like that.
Out of curiosity, does the AHT work on your wife's machine? If not, there could be a problem with the install disc itself, and if so, you might be able to get a free replacement under warranty.
Good luck!

Apple Hardware Test- oddity

Tonight I ran the Apple Hardware Test on my new iMac. System profiler correctly shows 256mb of video ram.... AHT shows only 128mb.
I'm not concerned, but just curious if this happens on all upgraded vram 20 inchers...
iMac Intel Core Duo 20" Mac OS X (10.4) 2gb Ram, 256mb Vram

Just spoke with applecare and was told that engineering is still investigating this problem - the VRAM discrepency between apple hardware test and system profiler. The applecare rep did say that the system does have 256MB but could not yet confirm the problem was with AHT.

Apple Hardware Test on a late 2008 MBP new HDD

Hey Community!
I own a Mac Book Pro - Late 2008 shipped with OSX 10.5.5. Currently I a new 500GB HDD and a 265 SDD are running in my MBP. The Super Drive is in an external USB Housing. Current OS X is version 10.7.1.
I need to run the Apple Hardware Test, because sometimes the system seems to freeze for at least 30 seconds.
What I've already tried:
*) Holding down "D" at the startup -> nothing happens, normal startup
*) setting start volume to external fire wire optical drive, insert 10.5.5. Installation disc, restart, holding down "D" -> startup with installation wizard
*) same with 10.6 Installation disc
*) same with choosing the Backup Partition when holding down "Alt" at startup and then pressing "D"
Always, I was connected via WIFI and Ethernet.
Can someone give me an advise how to run the Apple Hardware Test, or how to reinstall it on the new SDD Harddrive, where my system is mounted?
Thank u and greetings from Austria
Claudio

Try using your disk utility to read the drives. I'm not at my computer now but if you go into utilities->disk utility you might be able to solve it from there.
Also try holding down the C key on boot or esc.

Apple Hardware Test doesn't happen???
