  • How do you start the hardware test on an imac with bluetooth keyboard

    How do you start the apple hardware test on an imac with a bluetooth keyboard as the instructions is to press the D key whilst restarting? And of course the imac cant see the keyboard whilst booting up as the bluetooth connection has yet to be established

    Have you tried following the directions for running it from the DVD? The instructions are on the Hardware Test link.If you are correct and it cannot due to the wireless keyboard not making a connection you will need to borrow a wired USB keyboard.  

  • How can I perform a hardware selftest on a iMac 2010 with Mavericks?

    Since a few weeks my mid 2010 iMac model with Mavericks installed "hangs-up" after not being used for some time. The only way to get it going again is to press the power button and power it up again. I disconnect all hardware but that did not help. I'm thing to perform a hardware self test but how do I do it. Keeping "D" pressed and reboot was not ok because my model is not supported. Please HELP!

  • How can you perform a factory restore on an iMac running mountain lion, without the use of an apple id

    Hello!
    I am a computer tech working for a computer company.  We have an iMac here in the store which a customer needs restored to factory defaults. 
    I have tried the following:
         - Using 'command + r' to format and reinstall mountain lion (it is requesting an apple id that has purchased the mountain lion OS)
         - Using 'option' on boot up, same seneraio
    Is their any other way to perform some kind of equavilent procedure that would ready a iMac for re-selling?
    It's almost as though I need to purchase a copy of the operating system that has already come preinstalled on this system.
    Im not a mac savy user, maybe it's something simple i am missing.  Any help with this would be greatly appreiated!  Thanks in advance!

    You must have the account credentials for the account that was used to purchase Mountain Lion (this iMac was upgraded) presumably the customer.

    Boot the iMac, go to Apple>About This Mac>System Report, post the model identifier here (under hardware, 2nd line down)

  • Need to perform a hardware test, but pressing D during startup is fruitless

    I've got some sort of glitch I need to work through.  I'm assuming it's hardware related, and I directly suspect the GPU, or maybe a lose connection thereto (symptoms are coming and going).  Symptoms coincided directly with an OSX update to 10.9.4, but that might just be incidental.  Unfortunately, upon startup, I can't load into the Hardware Tester/Diagnostics tool... pressing 'D' during startup leads me to looking at a grey screen for about half a minute, then the MBP just decides to load into OSX.  I've tried to perform this test about ten times now - same result each time.
    Here's a couple of pictures of my screen when the issue is playing up.  It's obviously rendering the computer unusable:

    I'm trying for a combo update reinstall of 10.9.4 right now.  But if you have any other advice i'm all ears.

    Yes.   In one of those photos i've provided it's the OSX recovery screen that is bugging out.  I seem to have a 50/50 hit rate in getting through - like I said - the symptoms are coming and going.  Once within OSX recovery menu i've fired up disk utilities to make sure i'm not dealing with a dying HD - disk utility is suggesting my HD is in perfect health and perfect working order.
    I just followed through with reinstalling the 10.9.4 combo update too - I still can't perform a hardware test.

  • Trouble running hardware test on 07 iMac with noisy fan

    Hello
    I have an 07 iMac with a noisy fan- I've tried vacuuming out dust from the back but want to avoid taking it apart if possible...
    I read online I should run the hardware test, but since I am running Mavericks the Apple support advice is to run the original OS X install disc and restart (holding down D or Option+D)...
    Long story short I got a replacement disc from Apple (I'd lost the original) but the iMac ejects it when I restart following the process above... could it be my bluetooth keyboard? Hopefully not since I no longer have the original hardwired one... or does anyone have any other ideas for either how to get to the hardware test... or fix the fan (without a third party app just stopping it)
    Thanks!

    Try holding down the Option key to get the one time boot manager screen then select the AHT. Not sure as Apple moved it around on different install discs but it might be on the Applications discs and not the OS X discs.

  • 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)…

  • I can not perform hardware test on 2011 imac with mavericks

    I unplug all devices from my iMac and held the d key and still can not get to the hardware test. The Mac store was able to perform it with a wired mouse even after I added more ram therefore I know it can be performed. Am I leaving something out?

    Read the instructions in Using Apple Hardware Test.
    If your iMac shipped with discs, you must run AHT while holding the d key while starting the Mac with its grey Applications Install DVD inserted in the optical drive.
    To force the Internet version of AHT to load: with two fingers hold option d while starting your iMac with a third finger.

  • How do I use Apple Hardware Test on a Mid 2010 macbook pro?

    This MacBook is now running Mavericks 10.9.1
    This makes it so I can't update the firmware to use Apple Hardware Test within OS X internet recovery as discussed in this article:
    http://support.apple.com/kb/ht4904
    Holding down "D" at boot does nothing
    Holding down Option + D gives me Apple Hardware Test that can't be run because the firmware isn't updated and can't be updated because the update can only be applied to systems running Mac OS X 10.7.2

    You need the origional grey disk 2 that came with the mac when new.  It contains the AHT and applications.  You can call Apple and order the disks.

  • How do I access the hardware test, How do I access the hardware test

    08 MacBook with newest Lion. Is there a startup that allows me to access the Hardware test? Don't have disks with me.kk

    Command D will do nothing. Option d will load the Internet version of AHT but that will not work on a 2008 MacBook.
    Booting while holding the d key is not likely to work either, since Lion tended to erase AHT on the boot volume.
    AHT must be run from your Mac's original Applications Install DVD. It can also be reinstalled on the boot volume, if desired.

  • Hardware Test on MacBook Pro running Mavericks not working, Help!

    Hi Folks,
    I am hoping someone can help me get the Apple Hardware Test working on my Mid-2012 MacBook Pro (model 9,1) running OS X Mavericks v10.9.5.
    It came with Mountain Lion pre-installed.  I successfully ran Apple Hardware Test when I received it by holding D while powering up.  No problem.  Since then I have done nothing involving OS X other than installing Mavericks.
    Recently I have installed some RAM and wanted to test it.  I find the Apple Hardware Test no longer works.  The mac simply boots into the username screen as usual.
    Here's what I've tried:
    0. Reading instructions on Using Apple Hardware Test - Apple Support.  Ensured Mac was plugged in, and confirmed I pressed D prior to grey screen, and confirmed I held it down.  No effect.
    1. Pressed Option-D while powering up.  No effect.
    2. Searched for .diagnostics directory in /System/Library/Core Services/.diagnostics
    It didn't appear to be there.  (I don't know why, I can only guess that the upgrade from Mountain Lion to Mavericks must have hosed it)
    So, I found instructions on how to obtain the AHT .dmg file for my version of MacBook Pro and downloaded it.
    It's at this link by the way:
    http://download.info.apple.com/Apple_Hardware_Test/022-5879-A.dmg
    Then copied the .diagnostics directory from the .dmg into the /System/Library/Core Services/ directory on my HDD.
    Tried again, pressing D after powering up.  No success.  Option-D, same thing.
    So, I don't know what else to do.  IEverything I have read indicates the test should run.  It doesn't.
    Can anyone help?
    BTW: I don't have an install disk.  System came with Mountain Lion pre-installed and I subsequently upgraded to Mavericks a while later.
    Thanks in advance,
    - BS

    Forget the code yoyu have a hardware problem. Only Apple, or a AASP, knows the codes and what they mean. Take it to a genius bar.

  • Blue screen of death with HDD Hardware Test error on iMac HELP!!

    My iMac is not starting up.  It just get the blue screen of death during startup.  It is a 2.66 mghz duo with 2gb 800 ram.  I was able to get the Hardware test to run and got an error of 4M0T/2/40000004: HDD-1560.  I am assuming it is an error with the internal hard drive since I have nothing else hooked up to the mac other than the keyboard and mouse right now.  Does this code mean my hard drive is completely shot?  Any help would be appreciated.

    4M0T/2/40000004: HDD-1560.  
    Either failing or failed   
    You can have Apple replace the drive at a nearby Apple store or an Apple certified repair shop.

  • Run hardware test on MacPro 2009 running 10.8.2

    Hello. I think I should run a hardware test on my MacPro early 2009 running 10.8.2. Restaring while holding D key does nothing, neither inserting the original install DVD and restarting holding the H key, nor restarting holding cmd-D (supposed to call up internet hardware test). Any other options (besides Apple Care, for which it is definitely too late, or walking to some hardware store)?
    Thanks

    For a machine that shipped with 10.5.x, the appropriate Apple Hardware Test for that particular hardware is on the second (Applications) disk. If you did not get a replacement for that disk, you should call Apple back and request that disk. There is no other disk that will contain the appropriate boot system for AHT.
    BTW, note that those disks were almost certainly not left out of the packaging. It is not uncommon for them to be overlooked. If you still have the packaging somewhere by any chance, search it very carefully, taking it apart to look everywhere. (You may think that expecting you to keep the packaging for a 2009 machine may be a little ridiculous, but some people - especially those who don't live near an Apple Store - like to keep the box from machines they still own, in case they have to send them off somewhere.)

  • After an apple hardware test on my iMac I got an error code ?

    So I did an extended hardware test on my apple imac and after an hour of testing i got this error code: 4MOT1/140000003: HDD-1363. The next day I did another hardware test on my apple imac but this time iI did a quick hardware test and after about five minutes of testing this time I got the same result except this time the 4-digit code or number after the 'HDD-' changed to a different one, like... 1476. So what does this mean, I mean my computer is working perfectly fine without any problems (except for that one time when my brother punched my iMac's screen really hard a couple of times and a couple of hard punches on the hard drive however it was working fine but he did it again and it froze the time he did it again and i had to restart it but everything was STILL working fine after I restarted it !) but when I do the Hard ware test I get those errors so what does this mean ? Is it possible to fix ? Would apple fix it for free as my warranty has expired ?
    All help appreciated
    Thanks

    don't know why, but try using Disk Utility to repair the drive:
    1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
    3. Click the First Aid tab.
    4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
    5. Select your Mac OS X volume.
    6. Click Repair. Disk Utility checks and repairs the disk.

  • Apple Hardware Test Question on iMac

    I did an advanced Apple Hardware test on my 09 iMac today to test it and to see what was making the buzzing sound. The advanced test revved up each fan when it tested the logic board and I can say it is the lower left fan making the buzzing, however once it reaches 2000+ RPM the buzzing goes away.
    The question i want to ask is after the test the optical drive fan stayed revved up at over 2000 RPM for a few minutes after the computer restarted, unlike the other two fans that went back to normal this fan took atleast 3 mins to go back down to normal rpms. Is this normal?
    Thanks
    Also does the HDD run when in a hardware test? as now and then during the test I heard a weird static sound coming from the HDD.

    I looked at iStat after restarting from the test and it showed that only the optical drive fan was running at high speed after the test, with the slight buzzing fan still buzzing at low speed. I could hear that the optical drive fan was slowly revving down getting slower and slower, iStat showed it was as well and now its back to normal rpm and not revved anymore. I just thought all fans would return to normal after the test unless the optical drive got hot during the test.
    The buzz is not too bad and is only noticeable in a quite room but I'm more concerned about the random grind/static sound the HDD is making ever so often. The sound is very quiet but can still be heard but i don't know what it is, well I know its not the sound of a HDD breaking as I know what that hears like.
