AHT Apple Hardware Test Download & Flash Drive

Hi guys,
I really need to test the hardware on a 13" MBP. Full spec below.
The machine has Yosemite installed & I don't have the original install disc.
Does anyone know where to download the Apple Hardware Test (AHT) files & how to go about using it with a flash drive and a restart?
I've read this can be done but have only found dead links on old websites.
Holding down 'D' or 'Alt+D' isn't working, which I believe is due to the new operating system not having AHT.
Thanks!
Macbook Pro Spec:
MacBook Pro "Core i7" 2.7 13" Early 2011

"Wanted to download this as I'm not sure I can put my hands on the original 10.3 install disc. "
You will need to find it as the AHT is on the *machine specific* System Install DVD 1. If you lost your System DVDs, 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.

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?

extract from kb article
PPPoE (where there is no router handling the PPPoE connection)
No
No

Yes
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

Cannnot start AHT Apple Hardware Test from Anywhere PERIOD

I cannot start the AHT. Apple hardware test for the life of me, been trying for days.
I have the latest Boot ROM for Internet recovery, as such, I did read the Apple doc for this and have memorized it.
I have an early 2011 MBP, I came with Lion and I upgraded to Mountain Lion.
I do not have install disk, it did not come with any.
I need a major guru, I think I have bad memory or a app app.
thanks

Did you take this portion of the support article into account?

Apple hardware test from firewire drive?

I can't find my restore dvds for my macbook. I have an image of the first disk copied via disk utility to a firewire drive. i can start my macbook from the firewire drive but i can't seem to get the hardware test to start. on the dvd you have to press the d key when the computer starts up. (http://docs.info.apple.com/article.html?artnum=303081) I can't get this to work with the firewire drive. does anyone know if this is possible. don't they do it that way at the genius bar?
thanks

Thanks eww.
I have booted from os 9 and deleted the ati drivers of the X.4 system folder. Now it boots and Im typing on it. I didnt run a dvd yet since I did a very basic intall, but at least the genie effect works. I understand that the cpu takes the graphic tasks when the video card cant handle, so I suppose I should expect poor performance...
But still, I wanted this machine to run pro tools in os 9, so I think I will do fine, and have x.4 for internet. I just need to test a bit more so that I dont miss a live recording thanks to the weird motherboard.
Also, the screen doesnt look very good without the drivers and it cant be adjusted in any way.
Will update if I find anything new.

Does the apple hardware test, test the optical drive?

I think my optical drive may have issues. Does the apple hardware test the optical drive?

No it doesn't.
What kind of issues are you having? Reading/writing? CDs/DVDs?

HT201257 Apple hardware test how to start it?

I haven't optical drive. So how can I start the Apple hardware test without optical drive? I have a 15 inch mid 2010 macbook pro.
I have the problem sometimes my display under osx or under windows 7 professional stay black I can't do anything and can only restart the laptop via powerbutton.

Apple Hardware Test for MDD G4

While the Apple Hardware Test download page (http://www.info.apple.com/support/aht.html) doesn't have links to them, I have found that there are downloads on apple.com for versions 1.2.7 and 2.0.1 of AHT. These are for the G4 MDD FW 400 and 800 models, respectively.
AHT 1.2.7:
http://download.info.apple.com/AppleHardwareTest/693-4821-A.dmg
AHT 2.0.1
http://download.info.apple.com/AppleHardwareTest/693-4817-A.dmg
I don't know if AHT 1.2.7 is intended for the 2003 MDD as well (since it's similar to the earlier FW 400 MDD), since Mactracker states that version 2.0.2 shipped with that model. From what I gather, for the 2003 MDD there was not a separate AHT disc but was rather the test was included on the 2 software install discs - but I don't have the discs myself to confirm.

for the 2003 MDD there was not a separate AHT disc but was rather the test was included on the 2 software install discs
You are correct. AHT v2.0.2 is on my restore disc. for a 1.25GHz SP MDD.

Apple Hardware Test on Macbook Pro Core 2 Duo (early 2007) with no DVD?

Hi,
My Mac is keep on freezing and I would really like to know what is wrong with it. (I did PRAM NVRAM reset 100 times... didnt help.)
I can't find my OSX Tiger DVD which was included when i bought my Macbook Pro in January 2007. So I've been reading through forums like crazy trying to find another way to run AHT (apple hardware test). So far I came up empty.
So my question is: If I upgrade from Lion (which is my current osx on this machine) to Mountain Lion, will I be able to use online AHT (option + d)? Or more general: is there any way to run AHT on my machine or any other way to find the broken component. or should i just throw it away?
Thank you.

Take your machine into your local Apple Store or an AASP and they will run free diagnostics. If there's a lot that needs to be done on your machine to get it back up and running, ask about Apple's flat-rate repair pricing. For less than $350, you could have a machine that is almost like new.

Apple Hardware Test had trouble reading env file

I had a couple crashes this pas month. Maybe once a week. I figured it was the RAM maybe but that passed memtest. I attempted to do Apples AHT Apple Hardware Test but when I try to boot to the disk using D. I get this message:
Apple Hardware Test had trouble reading env file
'Configs\AHT_default.env'
There is very little information on google or the net about this error.

Take the computer to an Apple store or an AASP. Whichever is more convenient for you.

Possible to create system software disc on USB flash drive to start Apple Hardware Test on mid 2009 iMac running OS X 10.9

Is it possible to create a system software disc on a USB flash drive to start Apple Hardware Test on mid 2009 iMac running OS X 10.9?

Hopefully, those dvd's are the correct ones. If not, it's possible to download the AHT for many models from Apple, & either make a bootable drive, or replace the files in the hidden /System/Library/CoreServices/.diagnostics folder.
see Download and run Apple Hardware Test (AHT) from a USB drive.
There are additional download details in the comments for some later models.

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.

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

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...

Apple Hardware Test (AHT) is GONE!! after Lion install

After installing Lion on my new early 2011 MBP the AHT is gone...
Pressing "D" will not load the AHT (it was installed and working fine in my MBP prior to Lion).
I called the APP hotline to inquire about it and the technician couldn't boot into the AHT on all the macs with Lion available to him.
(a report has been filed with the engineering team)
According to the newly updated KB: http://support.apple.com/kb/ht1509
QUOTE: "Some Macintosh computers that shipped with OS X Lion support the use of Apple Hardware Test over the Internet."
After pressing and holding the "D" key the Mac just loads into the desktop... There is no online AHT or pre-installed AHT available...
>> Is anybody else having this problem?? <<
If you are having the same problem maybe you should also report it to Apple: http://www.apple.com/feedback/ or the APP hotline...

HOW TO FIX THE AHT PROBLEM IN LION:
Just to clarify what Francisco was saying in Spanish:
> The original AHT that came preinstalled in the MacBook Pro (and maybe all other Macs) is found in disk #2.
> Originally I thought the AHT had a different partition on the HD but it ends up being an extension of the OS.
> This is not installed in OS X Lion, If you used the USB key or download it from the App Store, the AHT will not be included.
> So, to install it back in, you can either run the install from the DVD (just make sure you don't install iLife again and other files which you may not need)
OR
For Road Warriors
Since installing the bundled package will also install other Snow Leopard files; You might want to try this:
> Download Pacifist ( http://www.charlessoft.com/ )
> Drill down the CPUHelpFiles install package and only install the CPU_AHT package.
By the way, there is no way of undoing this, unless you want to reinstall Lion from the recovery partition.
> Restart your mac
> Everything should be A+ ok
> To test what you just installed restart the mac and hold down the "D" key before the screen turns white/gray. After a few seconds you should see the AHT loading screen:
Done! there is no need to have that DVD with you when you travel...

Apple Hardware Test AHT

Hi,
I would like to run the Apple Hardware Test (AHT) on my MacPro(2,1) and since I have upgraded from Panther through Leopard to Snow Leopard, I have misplaced the original installation disks that came with my Mac Pro. Is there anyway to run AHT without those original install disks? Is there somewhere to download the images that I need?
TIA .... Jon

You will have to call AppleCare and arrange to purchase replacements. There are no alternative sources for the AHT for your Mac Pro.
