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 do I find out what an error code found on running the hardware test, means?

After running the hardware test on my Mac Pro I got an error code of: 4HDD/11/40000004: SATA (4,0) -- HOW DO I FIND OUT WHAT THIS MEANS?

It means your one of your SATA Hard drives is having trouble (or possibly your DVD drive, but not likley).
Got good backups? Now would be a good time to try to make some if you don't.

HT201257 How can I run the hardware test when my USB ports and bluetooth doesn't work?

The USB ports and the Bluetooth suddenly will not work on my Mac Mini (2008). There is very little I can do except using Remote Desktop. To run the Hardware Test, the D key has to be pressed during startup. I got no key to press. Is there any other way to do this?

Sorry, focused on bluetooth issue. If USB and bluetooth are knackered, try an SMC reset:
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.

My Intel iMac only shows a blinking folder with a question mark when powering it up. What can I do besides running the hardware test of the original installer disc.

My Intel iMac only shows a blinking folder with a question mark when powered up.
I did run the hardware test of the original installer disc and no trouble was found and I am out of options. Does anybody have any advice what to do next

If the drive shows errors then repair, if after the 3rd pass of Repair Disk in Disk Utility it still shows errors it's telling you it's time to be replaced. Take it to your local Apple Store or AASP for repair, when it comes back use your backup (either Time Machine or bootable clone) to restore so you can pick up where you left off.

Can I run the hardware test when I have four different accounts on my mac 10.8.4, can I run the hardware test when I have four different accounts on my mac 10.8.4

Hi Noticed that the top of my mac is nearly too hot to touch. Did a search online and found out about the hardware test. Looked up online user manual for my mac (Processor 3.06 GHz Intel Core 2 Duo 10.8.4) and noted how to perform the test. However, when I keep my finger on the D button through start up it just brings me right to the screen where I have to sign in to my desktop account (there are four accounts on the desktop as it is a family mac). Am I doing something wrong.

Welcome to Apple Support Communities
First, you should know that it's normal that your iMac is hot at the top. Here are the fans, so it's normal that it's hotter than other parts. Before going further, download Temperature Monitor and tell us which temperatures it indicates > http://www.bresink.com/osx/TemperatureMonitor.html
If it gives dangerous temperatures, then you should run Apple Hardware Test. Looking at the processor the Mac has got, your Mac came with DVDs. Apple Hardware Test is in Mac OS X Install Disc, so insert it and hold the D key while your Mac is starting to start in Apple Hardware Test

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.

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/.

How do I get the hardware profile on a Mac Mini

Please excuse my ignorance, PC user but I do run Linux. I have a Mac Mini and can not relate to the way Apple does things yet. How do I get a hardware profile so I know what hides within the cute little box?

Welcome to the Apple Discussions!
Clicking through the "About This Mac" window opens the System Profiler application which lives in your /Applications/Utilities/ folder. You can open it directly from there instead of going through the window, if you like.

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

See this article

Hi there, anyone know whats the error code means?
4MOT/1/40000003:HDD-1344
I have my iMac 27" for 14 months, and it just passed the warranty ...
Is it the hard drive problem or other?
Thanks

How do you run a hardware test?

Seems like ppl are running hardware tests...how do you do this?

I already know how to do the Hardware test. I am talking about the Apple Care CD that comes when you buy Apple Care. This CD is supposed to boot the machine and run Techtools. It does not, I was wondering if anyone has been able to boot the Apple Care CD. I did find another thread where this is a problem. It sounded to me like he said he could boot from his Apple Care CD I wanted to know how he did it. Some people have complained about the issue here

Running Hardware Test from second Mac?

My wife has a 2.4 GHz Intel Core 2 Duo iMac. It has a faulty DVD drive - actually a disc has been stuck in there for some time and we haven't been able to get it out. That is not our current issue, although it makes troubleshooting much harder.
Her iMac is getting slower and slower and I promised I'd run some tests. I can't run the Hardware Test on that machine from the original install disc because of the faulty DVD drive. I'd like to run the test remotely from my MacBook Pro but can't work out how to do that. I have tried booting her Mac in Target mode where I can run Disk Utility on my machine and repair her hard drive but when I insert her original Install Disc in my laptop there is no Hardware Test visible on it. I have tried to get access to my DVD drive from her iMac but 'DVD or CD Sharing' being turned on in 'Sharing Prefs' on my machine doesn't seem to bring up any shared discs on her computer. Maybe it's still trying to access her faulty DVD drive?
Is there anything I can do here to run some hardware tests on her machine? I'd like to do that before I start doing clean installs of the Mac OS on hard drives etc. I'm a bit stuck.
Thank you

Five ways to eject a stuck CD or DVD from the optical drive
Ejecting the stuck disc can usually be done in one of the following ways:
1. Restart the computer and after the chime press and hold down the
      left mouse button until the disc ejects.
2. Press the Eject button on your keyboard.
3. Click on the Eject button in the menubar.
4. Press COMMAND-E.
5. If none of the above work try this: Open the Terminal application in
      your Utilities folder. At the prompt enter or paste the following:
        /usr/bin/drutil eject
If this fails then try this:
Boot the computer into Single-user Mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.
Running the AHT doesn't make much sense for fixing slowness. If the computer is working, then there is no hardware failure. See the following:
Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with visits to:     OS X Maintenance - MacAttorney;
                                  The X Lab: The X-FAQs;
                                  The Safe Mac » Mac Performance Guide;
                                  The Safe Mac » The myth of the dirty Mac;
                                  Mac maintenance Quick Assist.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X 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.
Repair the Hard Drive - Lion/Mountain Lion/Mavericks
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites Menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD disk icon and click on the arrow button below.
When the recovery menu appears select Disk Utility. 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, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Restart your computer normally and see if this has helped any. Next do some maintenance:
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
Suggestions for OS X Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
Mac OS X Snow Leopard and malware detection
OS X Lion- Protect your Mac from malware
OS X Mountain Lion- Protect your Mac from malware
About file quarantine in OS X
If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
Troubleshooting Applications
I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
    used to manage backups and to restore backups. Time Machine
    requires a backup drive that is at least twice the capacity of the
    drive being backed up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Referenced software can be found at MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

Cant run apple hardware test

I have a G5 20" iMac, intel based. I've been trying to perform a Apple Hardware test but am unable to get it started.
Any help?

Thanks. Yes, I have a late 2007 20" imac. The model I have is a 2 GHz Intel Core 2 Duo, with 2 GB 667 MHz DDR2 SDRAM of Memory. I have a 320 GB Hard drive. The disks that came with the computer when I bought it in 2009 from Apple (3 of them) say iMac G5. I have 2 G5 Mac OS X install disks and a G5 Add'l Software and Apple Hardware Test Disk.
My problem started a couple of weeks ago when I would be getting the spining rainbow beach ball. I've opened Utility Disk and have Repaired Disk Permissions.
When I tuen on my computer I follow the instructions to the letter (from the link you gave me, I already had that and have tried it a few times) and it still will not start the test.
Each time I try it, I get the grey progress bar underneath the Apple Logo and spinning grey gear. The progress bar goes about a third of the way and ends then, the blue screen appears and my login window appears.
I have tried to run the Hardware Test by booting from the Install Disk, and from the Hardware Test Disk as well and the same this happens.
No matter what I do I can't seem to get the test to start, nor, start my computer without this Grey Progress bar underneath the Apple Logo and spinning gear.
I susspect I need additional Ram installed, but do not know how to check my computer to find out.
Lastly, the computer will only work for about 5 - 15 minutes normally after logging on. After this time the rainbow beach ball comes back and even the simplest of task can't be performed with a wait for the beach ball to stop and go away...
I'm stuck and don't know how to proceed...
I have $0 money left to invest in a certified Apple technician to come to the house to fix the problem...
Help....
Thanks,
Brian
