How long should the Apple Hardware Test (AHT) run?

II'm running the AHT on a 2012 quad core i5 iMac 16gb/3TB .....the progress bar moved quickly to about 7/8 done, about 4 minutes, but now has been sitting there for 40 minutes.
can anyone provide experience or input as to how long I should expect it to sit there?
thanks

If you run AHT in extended mode it can take over an hour to run, one factor is the HD capacity.

Run the Apple Hardware Test (AHT) from a external drive possible?

Hi my DVD drive is dead and i need to do a hardware test now but my macbook pro spits the dvds out., does anyone have experience with running AHT from external drive ?

What are you using AHT for specifically? Could you instead use a utility like Rember for checking RAM, which does a better job IMO than AHT?
-mj
i got it back from a authorized apple center that replaced the logic board and video card but now my dvd drive does not work and i can not test it with the original dvds, it was a recall on apples part for a faulty video card.
i want to test the v card as well as anything else i can do to see if someone snatched the original dvd drive becuase this thing was working before i took it there

On first plug-in of iPhone 4S, how long should the apple appear?

My new iPhone 4 has been plugged in for the first time for about 2 hours. Immediately upon plug-in, the Apple logo appears, but nothing more happens. All buttons are non-responsive.

Reset the iPhone, hold both home and power buttons until the iPhone begins to restart. Usually takes about 10 seconds of holding both buttons.
If still nothing and you decide to Restore again. Restart computer. Open iTunes on computer. Connect iPhone to computer. Hold both home and power buttons until iTunes recognizes iPhone in Recovery Mode. This usually takes about 20 seconds of holding both buttons. Restore the iPhone Firmware.
If still problem, all iPhone 4S have full Warranty, make Genius Reservation and take iPhone to Apple for resolution.

How long should the apple protection plan take to register?

it says it has been registering since yesterday

Are you referring to Apple Care? It should update within a minute.
Where did you buy it? You have to be careful if you got a code from eBay or similar "retailers"...

Yet another pointless question about the practically non-existent iMac G5 Apple Hardware Test (AHT) disk.

I have a 17" iMac G5 (iSight model) also known as model A1144, PowerMac12,1 or MA063LL/A.
Where do I download the Apple Hardware Test (AHT) disk for this machine? Apparently nowhere. However, it would really help me on my quest if I knew what I was looking for.
Does anyone know what AHT version is compatable with my machine? 2.2.1? 2.3.1?
How about the part number on the disk? I have some Intel disks that say 2Z691-5734-A that (obviously) won't work.
Is the AHT on Disk 1 or Disk 2? I'm starting to think there never was an AHT for this model.
Where do I get those ASD disks the so called "geniuses" have?

Disk 1: 2Z691-53179-A
Disk 2: 2Z691-5493-A
Compatible with eMac (2005), iBook G4 (Late 2004), iBook G4 (Mid 2005), iMac G5 17-inch (ALS), iMac G5 20-inch (ALS), iMac G5 (17-inch iSight), iMac G5 (20-inch iSight), iMac (Early 2006 17-inch), iMac (Early 2006 20-inch), Mac mini, Mac mini (Late 2005), Mac mini (Early 2006), MacBook Pro, Power Mac G5 (Early 2005), Power Mac G5 (Late 2005), PowerBook G4 (15-inch Double-Layer SD), PowerBook G4 (17-inch Double-Layer SD)

AHT I think was on a seperate CD.
Thanks Kappy, if v2.2.1 then search for...

The error code 4MOT/4/4000003:HDD-1393 has shown up from the apple hardware test. What should I do about this?

My iMac has been running a little hot, it was suggested to run the Apple hardware test (AHT), as heat can cause problems witht he hard drive.
The AHT revealed the error code 4MOT/4/4000003:HDD-1393 which I assume means a hard dtrive problem. But, what do I do. Is this a critical error or a minor fault. Everything is running as normal, but the machine is getting a little hotter than usual.

This indicates problem with HD fan.
Exact nature of the problem is only known to Apple.
We have no way to interpret this error code.
Keep a backup of your data.
When you get a chance, take the Mac to the nearest Apple store to have it tested.
Best.

I can"t open the apple hardware test from the applecare support website

i received the applecare training program for my birthday and while exploring the applecare service source website i found a image file of the apple hardware test (AHT) for each model along with a pdf of the service manual and a pdf of the AHT service codes. The problem i'm having is, i cant open the image of the AHT.

After downloading that image, open it and it will show up mounted in your desktop. Then, open Disk Utility (in /Applications/Utilities), right-click your Apple Hardware Test image in the sidebar and burn it to a DVD. Finally, start your computer from the disc, holding the C key, so Apple Hardware Test should start, always that you have the correct version for your computer.
You have Apple Hardware Test in the Applications disc that came with the computer. In that case, hold the D key while your computer is starting

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.

How can i get or download the apple hardware test for a macbook pro made in 2012 running Mavericks 10.9.3

Does anyone know how can i get or download the apple hardware test for a macbook pro made in 2012 running Mavericks 10.9.3. Thanks.

Sean and Andy -
I have to agree with Andy here. I am having the same problem on a mid 2010 MBP (6,2). I have already read the AHT info provided by Sean's link, and they are less than helpful. I'm sure they will be helpful to those who find that they work, but they are confusing if this is not the case. For example, my MBP(6,2) came with ONE (not two) installation disks, so the instructions don't work for me. Another issue is the instructions confound the descriptions related to the MBP, the original (delivered) software (OS X version), and the current installed OS X upgrade software.
So here's what does NOT work for me...
     (A) I cannot install 'Disk 2', since I never received this with my original (new) purchase in mid 2010.
     (B) I have checked my firmware versions and they are all up to date, as per Apple's information.
     (C) As suggested in another thread, I looked for /Library/Core Services/.diagnostics and it was NOT present. I followed his instructions, downloaded the correct (I believe) dmg, and installed it. It is in the correct place, and I can see all the invisible files using Pathfinder.
     (D) When I re-start holding down the D key (immediately), it just goes through the normal boot routine; no evidence of AHT.
     (E.1) When I re-start holding down OPT-D, I get a spinning globe, and then it prompts me for a network (wi-fi) connection.
     (E.2) For some unknown reason, the prompt identifies between 2 and 5 of my --neighbors'-- routers, but does not show mine. (??!!)
     (E.3) The routers are listed alphabetically; however, my router SHOULD be at the top of the list by this criterion, but it is nowhere to be seen.
     (E.4) The 'internet recovery' process then allows me to enter a network name AND password. I do this, for my current wi-fi router, and the process rejects it as an incorrect login ID. It is NOT an incorrect login ID!
So, now asking Sean and Andy (or anyone else) for further suggestions... ??? As Andy suggested, many people ask questions here because they have -already- worked through the 'official' recommendations, and have found them to be inadequate.
Any advice would be appreciated! TIA.
Ed

How do I run the Apple Hardware Test? Its not on my DVD and the Internet-connected version tells me my computer isn't supported!

I have a mini - late 2010 2.4 ghz core 2 duo - that just started black-screen crashing and failing to wake from sleep. Up to a few dasy ago this was a really bulletproof machine! When trying to restart it afer a crash it sometimes emits three weak beeps (sometimes more).
Apart from spontaneous motherboard failure (??) I can only guess that the RAM failed (an 8GB upgrade installed last fall). I pulled one 4GB RAM board and the mini booted again! But it still sometimes fails to wake from sleep, and sometimes give the three beeps. I've run REMBER (a memory test program) on one of the RAM boards and it passes the test. My next step is to test the second one -- but whether it passes or fails there seems to be something else going on.
I'd love to try the Apple Hardware Test but:
- pressing D on startup has no effect (even when starting up with the original install DVD)
- pressing Option-D brings up an Internet-loading screen that brings up a Hardware Test screen then tells me my computer is not supported.
Is the AHT simply unavailable for my model of Mac? And/or is there any way to test my hardware?

The 2010 Mac Mini's came with a 2 DVD set, a Mac OS X Install DVD (22691-6657-A) and an Application DVD (22691-6658 -A). The Apple Hardware Test is on the Application DVD (22691-6658-A).

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.

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.

Where do I find the apple hardware test

Hi, I'm trying to find the apple hardware test. The article here: http://support.apple.com/kb/HT1509 does not help me - I've tried pressing the D key, but the test won't start. My version of Snow Leopard only has one DVD (10.6.3). I rebooted from the DVD and had a look in the Utility section, but could not find the AHT there either. Any help would be greatly appreciated!
Thanks in advance,
Veronika
Edit: OK, I see that it should be located on the original installation disks. However, I never had those - my Mac was once repaired under extended warranty (new harddrive), and they kindly upgraded me from Tiger to Leopard all those years ago. Any other ideas?

Replacement disc(s) from Apple: 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.

What Do I Put On the com.apple.Boot.Plist to Make Snow Boot to the Apple Hardware Test By Default?

Hi. My main OS is 10.7.2 Lion but I had installed Snow 10.6.8 into a USB external drive. I will use Snow for apps that run well in it and for the Apple Hardware Test which is was my main reason why I installed Snow. Whenever I boot to this iMac's Snow DVD installers (disc 1 or disc 2) or to the one installed on the external USB drive and press D before the gray screen and 'ding', it doesn't want to go to the Apple Hardware Test. I want ot use AHT because I have no budget for similar apps like TechTool Pro.
Why is pressing the D not working by the way?
Is there a way to edit the Snow's com.apple.boot.plist to always boot to Apple Hardware Test (AHT)? What should I write in it. I'll be using Smultron to edit the plist instead of Terminal.
Thank you in advance.
Gbu.

Put the AHT disc into the machine, restart, holding down the D key. AFAIK, you can't do the way you're envisioning.

About the Apple Hardware Test in Replacement Application Disc...

I would like to know if an Applications Disc replacement ordered from AppleCare will include the Apple Hardware Test or AHT. A few months ago I had to reorder both my OSX install and Application disc because they were damaged out of the box. Now I know that Apple send the correct disc because the replacement disc have the same part number as the original ones, however the replacement application disc does not have the small test that says: "For Apple Hardware Test, press down the "D" key on startup." (or something like that) as the original one does. Which makes me wonder if indeed the replacement application disc sent by AppleCare really includes the Apple Hardware Test.
Tell me what you think, Does a replacement Application disc sent by Apple include the Apple Hardware Test?
Now, I must tell you that my current complementary phone support has expired and I am waiting to get AppleCare but that won't be after January 2011 (I am a college student, and I am saving money for the AppleCare extended warranty).
Thank you for your assistance in this matter.

I understand that, however my MacBook Pro is a 2010 one and the report says that the Apple AHT is in the Applications Disc since it was bought in a Snow Leopard era. The article clearly states that after 10.5.5 AHT will be in the original application disc that comes in your computer, and as posted above my application disc was damaged out of the box. That's why I odered a replacement application disc. However, the new application disc does not have a text that indicates that says "For Apple Hardware Test, press the "D" key on start up" as the original application disc, it just says 15" MacBook Pro Application disc. I assume that the AHT should still be in the replacement disc because it has the same part number as my original disc. Anyways, I read the whole article and it does not mention anything about AHT in AppleCare replacement disc.
I hope this clears up some things about this post.
