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/.

MacMini 2010 4,1 how to run Apple Hardware Test from /System/Library/CoreServices/.diagnostics folder

I have a 2010 Mac Mini4,1 with SnowLeapard and plan to upgrade to Mavericks, but can't run Apple Hardware Test from my applications disk 2 that came with the machine. For some reason the Mac can read it and kicks it our after about a minute. Seems to be able to reado other disks, so this one may be corrupted. I found info on this community that says that the AHT is on the hard disk and I found it here /System/Library/CoreServices/.diagnostics using terminal. When open that folder using terminal it open a window with that folders contents. My problem is I can execute the only unix executable in that folder. It responds with "No application knows how to open /System/Library/CoreServices/.diagnostics/diags.efi"
Can someone help me out here or if there is downloadable somewhere on line that I can get?

My 2010 4,1 Mac Mini still has the HW Test on the Internal HD after updating it to Lion, Mountain Lion and Mavericks.
see > Using Apple Hardware Test
Additionally if your using a wireless keyboard and it is not invoking the Hardware Test using the D key immediately after the chine, then you may need to use a USB keyboard. Adding that any Apple, PC or generic Logitech USB keyboard should work for invoking the startup commands.

How to run Apple Hardware Test on Mac Pro with ML preinstalled?

I have Mac Pro 5.1 (2012) which came with Mountain Lion preinstalled. It didn't have install DVDs. How do I run AHD? Restarting with D, or command+D, or option+D didn't work. It would just restart the OS. And Mac Pro didn't support Internet AHD eather.

Thank you for your reply, Carolyn.
I read this article. None of those applied to my case:
my Mac Pro came before 2013 and it doesn't have Apple Diagnostics built into it,
it doesn't have Apple Hardware Test built into it,
and my Mac Pro came with Mountain Lion preinstalled and it did not have system software disc or USB flash drive.
Restarting while holding down the D key simply doesn't work it just reboot back to the desktop.

How to run apple hardware test with no cdrom?

My MacBook Air won't recognise old or new hard drive and I believe I may have a logic board issue. My external CDROM has also just stopped working due to the wire being split some. I have two questions, can I get a replacement wire for the CDROM and can I run Mac hardware test on my 2008 MacBook Air without a CDROM? I still have the original CD1. I am currently booting the mac from a Lion installation on an external HDD attached to the USB port.
If the answer to those is no, where can I sell this stuff for scrap?
Thanks

How do I run Apple Hardware Test on a 2012 MacBook Air with 10.8.4?

Hello everyone,
I am trying to run Apple Hardware Test on a mid-2012 MacBook Air with 10.8.4 installed. Whenever I restart and hold the letter D my computer goes into internet recovery mode and asks me to connect to Wifi... Please help, thanks!

Using Apple Hardware Test on computers with OS X 10.7 or later
Mac NoteBook and Desktop computers shipping with OS X 10.7 or later have a partition on the hard drive or flash storage that contains AHT. To start AHT on these computers please follow these instructions:
Press the power button to turn on your computer.
Press and hold the D key before the gray startup screen appears.
It takes a minute or so for AHT to start up and inspect your hardware configuration. While this is taking place, an icon appears on the screen:
When the process is complete, select your language and click the right arrow. If you aren't using a mouse, you can use the up and down arrows to select a language and then press the Return key.
The AHT console appears. You can choose which sort of test or tests to perform:
To perform all of the basic tests, click the Test button or press the "T" key or the Return key.
To perform a more thorough diagnostic test, select the "Perform extended testing" checkbox under the Test button before you click the Test button.
Note: Your test results will appear in the window in the bottom-right of the console.To exit AHT, click Restart or Shut Down at the bottom of the window.
Some Macintosh computers that shipped with OS X Lion and later 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. An Internet-enabled connection via Ethernet or Wi-Fi is required to use this feature. Internet-based AHT functions the same as AHT on the hard drive or flash storage outlined above.
The Mac NoteBook and Desktop computers listed in Computers that can be upgraded to use OS X Internet Recovery will require a firmware in order to support the Internet version of AHT. Without this update you may see the behavior discussed in this article.

How to burn Apple Hardware Test with 10.7 bought on the App store

Hi Community,
My friend has a MacPro with 10.7 on it. He upgraded his OS by buying it on the App store.
Now he has a weird screen at start up
We would like to run Apple Hardware Test on the install DVD but as mentioned he bought it from the App store.
The only file we get is an installer (4.2 GB) but it is not a start up disk.
Has anyone an idea of what could be done ?
Thanks in advance for your help.
Denis

Apple Hardware Test can be invoked on Lion installations by holding D while starting from the internal HD. If that does not work try Option D as that will attempt to load an Internet version of AHT.
I do not know of a way to burn AHT alone to DVD, but the disc that originally shipped with his Mac Pro will have AHT on it. Booting from that disc while holding the D key will load the disc's version.

How to run the Hardware test on a Mac mini 2015 ?

how to run the Hardware test on a Mac mini 2015 ?

Welcome to Apple Support Communities
New Macs come with Apple Diagnostics instead of Apple Hardware Test, but their purpose is the same: check that your Mac's hardware is working properly. See -> https://support.apple.com/kb/PH18765?locale=en_US
To run it, you only have to hold down the D key while your Mac is starting up, and follow the steps.

How to access Apple Hardware Test?

I just installed a fresh copy of Lion over Snow Leopard hoping that I woul be able to use the AHT but it just starts up like normal when I hold the D key... I've tried it a billion times. Anyway I can put the AHT on my iMac? It's an A1224.

When you upgrade OS X or you erase the hard drive, Apple Hardware Test stops being saved on the hard drive. If you want to run Apple Hardware Test, you have to insert the Mac OS X disc which came with your computer and start the computer holding the D key. Read > http://support.apple.com/kb/ht1509

My Mid-2011 iMac with pre-installed Lion can't load AHT (Apple Hardware Test) over internet

I have a Mid-2011 iMac (3.4GHz) of which Apple's Support document for the Apple Hardware Test (http://support.apple.com/kb/ht1509) says:
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.
Well, this doesn't work for me. My Mac is on a DHCP-supporting router which has constant internet connection. Yet, when I turn off the Mac and then on again, holding the D key down even before the screen turns on, the Mac does indeed react to this key as it's then turning the screen on and taking another about half minute before it continues with the boot process along with showing the Mac symbol. Without the D, the Mac symbol comes up quickly.
So, it appears that the iMac is indeed trying to get AHT over the internet. Just that it doesn't succeed in it, and probably timing out after a while.
Any suggestions how to fix this?

Re
extract from kb article
PPPoE (where there is no router handling the PPPoE connection)
No
No
Captive-Networks (where you click an "Agree" button to access the Internet)
Yes
No
Proxies (where specific proxy servers must be configured in network preferences)
No
No
Certificate-based authentication / 802.1x
No
No
try check if you are in that case for your internet acces ?
could be a firewall problem too , if is possible try desable firewall ( or any internet filter )
no you can not see a wifi selection if you are wired ( using cable )
by the way D key for AHT need to be pressed AFTER start up sound , and hold at min one minute

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.

How to launch Apple Hardware Test from a USB optical drive?

Hi all!
First off, and before you guys starting proposing solutions I can't implement, I don't, repeat DON'T have a Firewire optical drive, nor am I going to buy one: I recently had to buy a USB LG optical drive to compensate for my SuperDrive going AWOL on me. I used said drive to reinstall OSX about a month ago, so this LG drive works just fine, thank you.
The thing is, I'd like to conduct an Apple Hardware Test, and I know you have to boot from OSX CD n°1 (in my case) to do that. Alas, since I can't boot from the CD in my SuperDrive by keeping the D key down, all I have is this LG thingy, and I wonder how I can conduct my hardware test with a USB optical drive.
I'll sum it up for you:
1) My SuperDrive isn't working, stopped working about the same time I installed this EFIng (guffaw, guffaw) Security Update 2009-001;
2) I don't have a Firewire optical drive;
3) All I have is a USB optical drive and MacOS X CDs.
4) Booting with the OSX CD in my USB optical drive and keeping D, C or alt keys didn't help.
I read in another forum that you could somehow copy the content of the OSX CD on a flash drive, then boot from the flash drive and conduct an AHT, but I'm not sure how it can be done.

Hi!
Looks like we posted at exactly the same time, Glynn! LOL
Anyway, I did just what you said, drag'n'drop and all. The problem is, when I boot from the USB hard drive, it's exactly as if I were booting from the CD: first I'm asked to choose a language, then the install screen appears, and I can either reinstall on my startup disk from the USB hard drive (that's kinda cool, but I don't think I leave in on my USB hard drive, which can only content 40Gb, because I've almost 25Gb worth of data to retransfer soon...
So, in a nutshell, I couldn't find Apple Hardware Test anywhere. I even explored the CD content, but there are so many files...
What's my best option now? Could AppleJack help me here? Can I install AHT on my startup disk and boot on it using a special set of keys?
Almost time to go to work. A 5 minute walk, though...

How to obtain apple hardware test for MacBook Pro (15-inch, Mid 2009), how to obtain apple hardware test for MacBook Pro (15-inch, Mid 2009)

I no longer have the software disk (OS10.5) that came with my MBP in July 2009. I only have the $10 Snow Leopard disk from Apple, which does NOT seem to contain any Apple Hardware Test (AHT). I have tried starting while holding d or option keys to no avail. Does neither my laptop nor OS 10.6 install disk have AHT? If not, can the appropriate AHT be obtained? My wife has an older MacBook & her original 10.5 install disk, but it will not launch AHT in my MBP. Any suggestions?
Thanx

I like the advice to contact Apple and simplky pay for a new AHT. I did that, giving them the serial number of my MBP and indicating it was a June 2009 model, 2.66 gHz Core 2. However .....
I received yet another Apple FedEx shipmet with yet another different Mac OS X Leopard install DVD; this makes three in all!! Just as with the 1st DVD, these two will NOT mount on my desktop, are NOT seen by Disk Utility (or by Drive Genius) and cannot boot my MBP laptop in either of 4 different modes: (1) start-up with "d" (2) start-up with "option d" (3) start-up with "option" (4) start-up with "c". Apparently none of the disks I received have Apple Hardware Test on them, although that is what I paid for in early December. It may be that the last two disks really do have Mac OS X Leopard on them, but because I am now running OS 10.7.5 (purchased from App store with no AHT), the disks cannot be seen by my laptop.
          The two most recent incorrect DVDs I received have the following part numbers:
                    SRF2Z691-6037-A [indicated on packing slip 10.5 Retail-International]
                    SRF2Z679-6341-A (indicated on packing slip 10.5.6 Retail (PCrly 09) In]
          I happen to have MacTracker app 7.2.1. It indicates that my laptop is a MacBookPro 5,3 model A1286 EMC2325 and requires Apple Hardware Test 3A171. Apple never sent me the correct AHT.
          I suspect that Apple's cost to ship 3 incorrect DVDs by 1- or 2-day FedEx vastly exceeds the $17.44 price I paid for a working version of AHT for my computer, but have yet to receive.

2011 Imac. Won't run Apple Hardware Test

Upgraded to Yosemite and now my DVD drive doesn't play or burn. I'm trying to do an Apple Hardware Test. That doesn't work either. I follow the instructions to shut down the computer and hold down on the D key. That is not working. It just continues its start up
I've tried and it has failed about half a dozen times. Is there another way to get it to work?

FWIW. Mine boots into AHT with disc 2 inserted, restarting, and holding down the D key. Alternatively, 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 SL boot volume's /System/Library/CoreServices/ folder.
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

Big Disappointment with iMac Intel (Late 2006) and Apple ProCare.

I've been a Mac user, Mac enthusiast, and Mac advocate for over 15 years. I've owned multiple Macs. One of my latest acquisitions was an Intel iMac in October 2006.
A few weeks ago, the iMac started freezing and shutting down intermittently. After days of online discussions trying to figure out the problem, I finally ran out of patience, and took the iMac to my local Apple Store on 7/23/07.
Two days later, I was told that the Logic Board needed to be replaced. It's been two weeks, and every time I contact the Apple Store, I am told that they are still waiting for the part.
Meanwhile I am left without the main computer in my house, where I store all my documents, music, photos and videos. In addition, I have a ProCare membership, and even purchased the Extended 3-year warranty. In this age of instant communication and express delivery, I cannot understand why it would take two weeks to get a part from Apple.
I am very disappointed with the Apple Care for a company with such a high reputation for service.
What are my rights as a consumer? How long do I have to wait before they offer me a replacement. How do I go about requesting a replacement?

"The question still remains: How long am I going to be in repair mode before the Apple store decides to offer a replacement?"
Hello Herold Merisier!
The answer is that since each case may be different, there is no real set policy in this regard, with decision making and customer satisfaction in the hands of managers.
I'm surprised to hear that there is any difficulty at all getting that logic board. I just don't believe that there is any shortage, and it does not take two weeks to get one there, unless no one cares about you, which would be an unacceptable attitude. There must be something else at play in this situation.
I would guess that due to an inability to handle the work in-Store, the repair of your iMac has been handed over to an AASP, either to be performed at the AASP or somewhere on the Store premises.
Due to the disruption of the iPhone events, the repair of your iMac might have dropped off the radar screen of the Apple Store's Manager, and also of the Manager of the AASP. The problem may be an overworked AASP (not your fault), with some lower level employee there trying to pass the buck back to the Store through their lower level employees, and then on to you.
If such is the case, the job of Managers and Assistant Managers is to be aware of such things and manage them, therefore your circumstance is extremely disappointing. The first thing to do is not to try and lay blame, but make certain that the Store Manager is personally aware of your situation, and (unless you know it's already been done) to ask that all your paperwork details be verified - that your warranty and AppleCare are actually registered and in effect for your iMac, that your ProCare is recognized as being on the record, and that your iMac's repair is not accidentally misplaced, but will now be given Priority. In doing that, someone might discover the cause of your delay.
I would guess that the Manager of your Apple Store is also not aware of your exact situation, as it almost sounds as if the Manager is on vacation, or something very much worse:(
Considering the iMac product line and the age and needs of your iMac, the cost to Apple and the Manager of the Apple Store to fully satisfy you in this case will be absolutely negligible. If it's possible for you to speak to the Store Manager today or tomorrow, I'd be surprised if your iMac, or a replacement, isn't in your hands by Wednesday at the latest.
If you are unable to speak to the actual Store Manager, and if the Assistant Manager to whom you then speak is unable or unwilling to resolve this for you within 24 hours, you should call AppleCare's toll free number and ask to speak to an AppleCare Manager about your lack of service problem and what the bottleneck might possibly be.

How to start Apple Hardware Test under OS X Lion

Since I made the upgrade to OS X Lion I cannot start Apple Hardware Test with the old method that works under Snow Leopard.
Under OS X 10.6.8 I used to keep D key pressed until a picture appeared in the middle of the screen. With Lion it doesn't work, even under Wi-Fi internet connection.
Any suggestions?
