On the one hand Apple now recommends you simply use the disks that came with your Mac on the other hand Apple says 'discs are dead' and removes optical drives from Macs. How crazy is this?
But great hint :-)

Had our esteemed moderator tested this hint, he would have found it doesn't work as described. System/Library/Core Services is only writable by the user when preceded by 'sudo'. Thus, the correct syntax should be

Yeah, you're quite correct! Sorry for the mistake.
Somehow I forgot to add that in when writing the hint (or I was using the root account at the time….)
Anyway, yes, sudo must be used. (It would be nice if the original hint could be modified. :))

Fixed it. Thanks for the catch.

Had out esteemed smarta$$ looked, he'd have seen that Baltutis below posted the correct command.
If you're gonna call someone out, be smarter.
sudo cp -R /Volumes/[your INSTALL DISK name]/System/Library/CoreServices/.diagnostics /System/Library/CoreServices

If you use the discs that came with your Mac, you can also simply install the 'CPUHelpFiles.mpkg' metapackage, usually on the Applications Install Disc (part of 'Install Bundled Software': select only 'CPU Help Files' and deselect everything else): this will install AHT and also the documentation files for your machine.


I forgot about the CPUHelpFiles package because other utilities in there (such as the processor pref pane seem to be broken now), but that does work if you would prefer not to use terminal.

Well, rather, the 'Processor' preference pane was an optional part of the Developer Tools (up to version 3.x for Snow Leopard), while 'CPUHelpFiles.mpkg' installs only AHT and the machine-specific documentation stuff inside '/Library/Documentation/User Guides And Information': so, it should be quite safe too install, as there are no extra utilities there.

Of course, *to* install (not 'too')...

I'm pretty sure this doesn't work if your boot volume is encrypted. You'd need to create a separate unencrypted boot disk/partition, boot to that, install AHT, then boot into AHT.

On encrypted systems, there is a small booter partition which contains the EFI application that asks for your password, loads the kernel from the booter partition and once the kernel found and unlocked your encrypted volume, system startup continues as usual.
If your system has the recovery system (and most Lion installs should have), it and the booter share a partition after your root volume. diskutil list will confirm there is this hidden partition called 'Recovery HD'. If your system for some reason does not have the recovery system, but you encrypted the root volume, the partition will be named 'Boot OS X'.
Either way, just mount this hidden partition ('diskutil mount Recovery HD' or 'diskutil mount Boot OS X') and then copy the .diagnostics folder to /Volumes/{Recovery HD Boot OS X}/System/Library/CoreServices.
After that, you can boot to AHT by holding D, like on unencrypted systems.
It is probably a good idea to copy AHT to the Recovery HD, regardless of the encryption status of your root volume, but I haven't tested if the firmware finds AHT there when the partition is not the first HFS+ volume on your primary disk.
Curiously, one can boot the recovery system, but not AHT, when the firmware password is set...

I just tried doing this, but there isn't enough space on the recovery volume to copy all of the files in the .diagnostics folder. : (

Maybe I'm wrong, but the command should be:
sudo cp -R /Volumes/[your INSTALL disc's name]/System/Library/CoreServices/.diagnostics /System/Library/CoreServices/

You are correct, BT! Slight difference, but then that's what makes things work or not!

FYI, I couldn't get 'D' to work on a 2011 MacBook Air. My drive is encrypted and I had a firmware password turned on. Once I disabled the firmware password, 'D' worked. That's a bit unfortunate, as what if my drive has died? How can I reach the recovery partition to disable the firmware password to get to the hardware test.

Apple Macbook Pro 2011 Specs

great hint but AHT is pretty worthless and no longer really used. If you want to run diags on your computer that will actually do something, use apple service diagnostics (ASD) for your model instead

I could not find my original disks, but was able to restore the .diagnostics folder from a pre Lion upgrade time machine backup. Had to show hidden files first, but then just went back far enough and restored that one folder. Boot while holding D worked fine.

HELP! Can't do ANY diagnosing on Late-2011 MBP w/ 16GB RAM! :-(((

Alright, I still don't understand how to find either the 'Holding the D' function and/or some other utility (3rd party or Apple) for those of us who have a (Late-2011) MacBook Pro!? No disks, just a useless SuperDrive and no USB stick either. I did make myself my own USB restore flash drive, however, and I also have the Recovery HD partition unhidden, mounted, but I just cannot seem to locate this '.diagnostics'...folder(is it?) or is it a pkg or a file? :-( System files are also visible, so I did some manual searching for the elusive diagnostic 'something-or-other'. No dice across the board. :(
I would really like to check my 2x8GB RAM chips, which, thus far, work perfectly fine and show up correctly everywhere they should, including System Info/Profiler, 'About this Mac', iStat Menus, Activity Monitor, and a few others. I just want to make sure, as I had not heard of that memory company before and the price was incredible ($139 shipped, no tax for BOTH from a seller on Amazon).
Thanks for helping! ;-)

I've got MacBook Pro (15-inch, Late 2011) with Apple Hardware Test originally accessed by holding D at startup.
However after restoring Mac OS X Lion by the Internet using Lion Recovery D-key stopped working. I've followed the tip and copied .diagnostics folder:
ls -al /Volumes/Macintosh HD/System/Library/CoreServices/.diagnostics/
total 48
drwxr-xr-x 3 root wheel 102 Feb 13 16:06 .
drwxr-xr-x 125 root wheel 4250 Feb 13 16:06 ..
-rwxr-xr-x 1 root wheel 22590 Feb 13 16:06 diags.efi
ls -al /Volumes/Recovery HD/System/Library/CoreServices/.diagnostics/
total 48
drwxr-xr-x 3 User staff 102 Jun 27 2011 .
drwxr-xr-x 4 User staff 136 Jun 27 2011 ..
-rwxr-xr-x 1 User staff 22590 Jun 27 2011 diags.efi
However the D-key still doesn't call AHT as expected.
What else should I try?

Hi, did you ever manage to get anywhere with this?

I confirm that this method still works with 10.8.5 installed on a Feb 2011 macbook pro.

On newer Macs (which shipped with Mavericks), Apple Diagnostics initially is on the Recovery HD; so, after mounting it with:
$ diskutil mount Recovery HD
... Apple Diagnostics is in the folder:
/Volumes/Recovery HD/
So, the best thing to do would be to make a copy of this invisible folder (personally, I zipped it and stored it on an external hard drive), in order to be able to restore it if you reinstall OS X (which also updates the recovery partition, removing the '.diagnostics' folder); when restoring it, also remember to restore the original permissions for the '.diagnostics' folder and its contents: i.e., essentially, root read-write, wheel read-only and everyone read-only.
Sadly, presently there seems to be no way to re-download Apple Diagnostics from Apple and reinstall it: so, if you didn't make the backup copy from your initial, out-of-the-box setup, the only option remaining is the Internet-based one, as also explained here:
(Probably, the situation is similar also for Macs which shipped with Lion and Mountain Lion (with AHT)...)

Most Mac users enjoy several years of trouble-free experience, but eventually, time will come when hardware problems arise. Although it rarely happens, problems can be caused by a motherboard issue, a failing hard drive, a GPU problem, or lack of memory space. Fortunately, Apple has a way to detect, prevent, and solve any hardware-related issue. Apple Hardware Test is the first step. You can use it to check if there are serious hardware issues to deal with. Don’t worry, because you can run the test yourself. We will teach you how below.

What Mac Models Can Run Apple’s Internet-Based Hardware Test?

Not all Mac models can run the Internet-based Apple hardware test. Some MacBook models need to use a local version of the hardware test, which has to be installed on the hard drive or saved on OS X DVD. Other Macs manufactured after 2013 can use the latest version of the Apple hardware test, which is called the Apple Diagnostics test. Here’s a guide on how to use Apple Diagnostics test. As for the only Mac models that can use the web-based version of the Apple hardware test are as follows:

  • 11-inch MacBook Air 3 (late 2010 through 2012)
  • 13-inch MacBook Air 3 (late 2010 through 2012)
  • 13-inch MacBook Pro 8 (early 2011 through 2012)
  • 15-inch MacBook Pro 6 (mid-2010 through 2012)
  • 17-inch MacBook Pro 6 (mid-2010 through 2012)
  • MacBook 7 (mid-2010)
  • Mac Mini 4 (mid-2010 through 2012)
  • 21.5-inch iMac 11 (mid-2010 through 2012)
  • 27-inch iMac 11 (mid-2010 through 2012)

It is important to note that the mid-2010 through early 2011 Mac models may require to update the EFI firmware before you can run the web-based Apple Hardware Test. If you are uncertain if you need to update the EFI firmware or not, you can do the following:

  • Go to Apple menu and click About This Mac.
  • A new window will open. Click the More Info button.
  • If your Mac is running in OS X Lion or the later version, select System Report. Otherwise, proceed to step 4.
  • Another window will open. Highlight Hardware in the left portion of the screen.
  • On the opposite corner of the screen, take note of the boot ROM version number of your Mac and the SMC version number.
  • Once you have these details, go to the EFI and SMC Firmware Update page on Apple’s website. Compare the versions you have with the latest available. If your Mac is running on an older version, you need to download the most recent version on the same web page.

How to Use the Internet-Based Apple Hardware Test

As soon as you have verified and confirmed that your Mac is capable of running the Internet-based Apple Hardware Test, you can start using it. Here’s how:

Apple hardware test macbook pro 2011 download
  • Turn off your Mac first.
  • If you are running a MacBook, connect it to an AC power source. Do not run the test with only your MacBook’s battery as the power source.
  • Press the Power button while holding down the Option and D keys. Continue until the Starting Internet Recovery message pops up on your display.
  • Wait for a few seconds. You will soon be prompted to select a network. Use the drop-down menu to choose from the list of available network connections.
  • Select a wireless network and enter the password if asked. Press Return or Enter. You can also click the checkmark button on your display.
  • As soon as you are connected to your chosen network, you will see a message on your screen that says, Starting Internet Recovery. This will take a while because the Apple Hardware Test will be downloaded to your Mac. Once it is completed, you will be prompted to select a language.
  • To select a language to use, use the Up and Down arrow keys or the mouse cursor.
  • The Apple Hardware Test will then continue to check what hardware is installed on your Mac. Again, this will take time.
  • Before you proceed with the actual test, it’d be better if you verify first what hardware was found so you can ensure that all your Mac’s components are correct and accounted for. Check if the exact amount of memory is displayed, along with the graphics and CPU specs. If you suspect that something is wrong, verify your Mac’s configuration by going to Apple’s support site. If the displayed config does not match with what your Mac model’s configuration should be, your device might be failing. To verify your Mac’s hardware specs, navigate to the Hardware Profile tab.
  • If all configuration details are correct, proceed with the testing by going to the Hardware Test tab.
  • Note that the Apple Hardware Test can support two different types of testing; a standard test and an extended test. While the standard test is generally a good option, the extended test is highly recommended, especially if there is an issue with your Mac’s graphics card or RAM.
  • To run the standard test, select the Standard Test option and click the Test button. At this point, the hardware test should start. It will take several minutes to complete, so just be patient. Do not worry if you hear your Mac’s fans rev up and down. That’s normal during the hardware testing process.
  • Once the test is done, a list of potential issues or a No trouble found message will be displayed in the test results pane. If there is an error, check what it is about. We listed some of the most common error codes below alongside their meanings:
    • 4AIR – AirPort wireless card
    • 4ETH – Ethernet
    • 4HDD – Hard disk (includes SSD)
    • 4IRP – Logic board
    • 4MEM – Memory module (RAM)
    • 4MHD – External disk
    • 4MLB – Logic board controller
    • 4MOT – Fans
    • 4PRC – Processor
    • 4SNS – Failed sensor
    • 4YDC – Video/Graphics card

These error codes generated by the Apple Hardware Test seem to be cryptic, and in some cases, only certified Apple service technicians can understand them. But because most of these codes are recurring, they’ve become known.

  • If no problem was found, you could continue running the extended test. It can detect graphics and memory problems better than the standard test. To do the extended test, select the Perform Extended Testing option and click the Test button.
  • If by any chance, you’d like to stop the test, just click the Stop Testing button.
  • Once you are done using the Apple Hardware Test, end it by clicking the Shut Down or Restart button.
