Before you beginï¿½ Important: If your Mac was released after June 2013, you will use Apple Diagnostics rather than Apple Hardware Test (AHT). See Using Apple Diagnosticsï¿½for instructions.ï¿½ Consider doing some preliminary troubleshooting to determine if your issue is related to hardware. You can try toï¿½determine if the cause of your issue is related to hardware or software by following Hardware test macbook pro 2012 issues in OS AHT can help determine which hardware component may be causing the issue.ï¿½ Before starting AHT, be sure to disconnect all external devices except the keyboard, mouse, display, andï¿½Ethernet adapter.

Also disconnect any external optical drives.ï¿½ If you are testing a Mac notebook, perform the following additional steps:ï¿½ You need to connect to AC Power when running the Apple Hardware Test on a Mac notebook.ï¿½ Set up your computer on a hard, flat, stable work surface that allows for adequate air circulation under and around the computer (such as a desk, table, or counter).Using Apple Hardware Testï¿½ Shut down your computer.

Then, press the power button to turn it back on.ï¿½ Press and hold the D key before the gray startup screen appears.ï¿½ It takes a minute or so forï¿½AHTï¿½to start up and inspect your hardware configuration.

While this is taking place, an icon appears on the screen:ï¿½ When the process is complete, select your language and click the right arrow. If you aren't using a mouse, you can use the up and down arrows to select a language and then press the Return key.ï¿½ The AHT console appears. You can choose which sort of test or tests to perform:ï¿½ To perform all of the basic tests, click the Test button or press the "T" key or the Return key.ï¿½ To perform a more thorough diagnostic test, select the "Perform extended testing" checkbox under the Test button before you click the Test button.Note:ï¿½Your test results will appear in the window in the bottom-right of the console.ï¿½ To exit AHT, click Restart or Shut Down at the bottom of the window.Some Macintosh computers that shipped with OSï¿½X Lion and later 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. An Internet-enabled connection via Ethernet or Wi-Fi is required to use this feature. Internet-based AHT functions the same as AHT on the hard drive or flash storage outlined above.Using Apple Hardware Test on computers with OS X v10.7 and earlierAHTï¿½is located on the Applications Install Disc 2 and should be included with your computer or the MacBook Air Software Reinstall Drive on a MacBook Air (Late 2010).

To startï¿½AHTï¿½on these computers make sure theï¿½Applications Install Disc 2 is inserted into the built-in optical drive, external Apple Superdrive, or for theï¿½MacBook Air (Late 2010) be sure theï¿½MacBook Air Software Reinstall Drive is inserted into a USB port. Then, follow steps 1-6 outlined in the previous section of this article.What to do if you get an error in AHTï¿½ Confirm that the power adapter is connected if you're using a Mac notebook.ï¿½ Confirm that all external devices are disconnected from your computer.ï¿½ Record any error code given so that you can give the information to a Mac Genius, Apple Authorized Service Provider, or Apple Technical Support Specialist.Learn moreTo determine what OS your Mac notebook or desktop shipped with, see OS X versions (builds) for computers. ï¿½TourStart here for a quick overview of the siteï¿½Help CenterDetailed answers to any questions you might haveï¿½MetaDiscuss the workings and policies of this siteï¿½About UsLearn more about Stack Overflow the companyï¿½BusinessLearn more about hiring developers or posting ads with us I would like to test hardware on a mac book pro model from 2009 with Mac Os X 10.9.2 installed.

This test is for Macs older than June of 2013.IMPORTANT: If your Mac was released after June 2013, you will use Apple Diagnostics rather than Apple Hardware Test (AHT). See Apple Diagnostics below for instructions.Isolating issues in Mac OS X (to hardware or software)https://support.apple.com/kb/TS1388Apple Hardware Testhttps://support.apple.com/kb/ht1509Apple Diagnosticshttps://support.apple.com/kb/HT5781Follow me:Twitter: https://twitter.com/JakeGeekTechPinterest: https://pinterest.com/geekouttech Macsï¿½ Mac Operating Systemsï¿½ Selecting Mac Hardwareï¿½ Mac Troubleshooting Tipsï¿½ Applications for Your Macï¿½ Peripherals and Add-ons for Your Macï¿½ Networking Your Macï¿½ New to Macï¿½ Tips for Using Your Macï¿½ Macs in Professional Useï¿½ Windows on Your Macï¿½ Do-It-Yourself Projects for Your Macintosh Computerï¿½ Mac News, Rumors & Events UpdatedJuly 28, 2016.You can use the Apple Hardware Test (AHT) to diagnose issues you're having with your Mac's hardware.

This can include problems with your Mac's display, graphics, processor, memory, and storage. The Apple Hardware Test can be used to rule out most hardware failure as the culprit when you're trying to troubleshoot problems you're experiencing with your Mac.Actual hardware failure is rare, but it does happen from time to time; the most common hardware failure is RAM.The Apple Hardware Test can check your Mac's RAM and let you know if there are any issues with it.

With many Mac models, you can easily replace faulty RAM yourself, and save a few dollars in the process. Which Macs Can Use the Internet-Based Apple Hardware Test?Not all Macs can make use of the Internet-based AHT. Macs that are unable to use the Internet version of AHT can use a local version that's either installed on the Mac's startup drive or included on your OS X install DVD.

2013 and Later Macs2013 and later Mac models make use of a newer version of the hardware test called Apple Diagnostics. You can find instruction for testing newer Macs using Apple Diagnostics at:Using Apple Diagnostics to Troubleshoot Your Mac's Hardware Apple Hardware Test Over the Internet Macs That can use Internet Version of AHT ModelModel IDNotes11-inch MacBook AirMacBookAir3,1late 2010 through 201213-inch MacBook AirMacBookAir3,2late 2010ï¿½through 201213-inch MacBook ProMacBookPro8,1early 2011ï¿½through 201215-inch MacBook ProMacBookPro6,2mid 2010ï¿½through 201217-inch MacBook ProMacBookPro6,1mid 2010ï¿½through 2012MacBookMacBook7,1mid 2010Mac miniMacmini4,1mid 2010ï¿½through 201221.5-inch iMaciMac11,2mid 2010ï¿½through 201227-inch iMaciMac11,3mid 2010ï¿½through 2012Note: Mid 2010 and early 2011 models may require an EFI firmware update before you can use Apple Hardware Test over the Internet.

You can check to see if your Mac needs the EFI update by doing the following:ï¿½ From the Apple menu, select About This Mac.ï¿½ In the window that opens, click the More Info button. ï¿½ If you're running OS X Lion or later, click the System Report button; otherwise, continue with the next step.ï¿½ In the window that opens, make sure Hardware is highlighted in the left-hand pane.ï¿½ From the right-hand pane, make a note of the Boot ROM Version number, as well as the SMC Version number (if present).ï¿½ With the version numbers in hand, go to the Apple EFI and SMC Firmware update website and compare your version against the latest available.

If your Mac has an older version, you can download the latest version using the links on the above webpage.Using the Apple Hardware Test Over the InternetNow that you know your Mac is capable of using the AHT over the Internet, it's time to actually run the test.

To do this, you need either a wired or Wi-Fi connection to the Internet. If you have the required network connection, then let's get started.ï¿½ Make sure your Mac is turned off.ï¿½ If you're testing a Mac portable, be sure to connect it to an AC power source. Do not run the hardware test using only your Mac's battery.ï¿½ Press the power button to start the power on process.ï¿½ Immediately hold down the Option and D keys.ï¿½ Continue to hold the Option and D keys until you see a "Starting Internet Recovery" message on your Mac's display.

Once you see the message, you can release the Option and D keys.ï¿½ After a short time, the display will ask you to "Choose Network." Use the drop-down menu to make a selection from the available network connections.ï¿½ If you chose a wireless network connection, enter the password and then press Enter or Return, or click the check mark button on the display.ï¿½ Once you have connected to your network, you'll see a message that says "Starting Internet Recovery." This may take a while.ï¿½ During this time, the Apple Hardware Test is being downloaded to your Mac.

Once the download is complete, you will see the option to select a language.ï¿½ Use the mouse cursor or the Up/Down arrow keys to highlight a language to use, and then click the button in the bottom right-hand corner (the one with the right-facing arrow).ï¿½ The Apple Hardware Test will check to see what hardware is installed in your Mac. This process can take a little bit of time. Once it's complete, the Test button will be highlighted.ï¿½ Before you press the Test button, you can check what hardware the test found by clicking on the Hardware Profile tab.

It's a good idea to take a cursory look at the hardware profile, just to make sure that all of your Mac's major components are showing up correctly. Be sure to verify that the correct amount of memory is being reported, along with the correct CPU anï¿½TourStart here for a quick overview of the siteï¿½Help CenterDetailed answers to any questions you might haveï¿½MetaDiscuss the workings and policies of this siteï¿½About UsLearn more about Stack Overflow the companyï¿½BusinessLearn more about hiring hardware test macbook pro 2012 or posting ads with us I purchased a Late-2011 MacBook Pro 15" used a month ago.

At the time of purchase, I successfully ran the Apple Hardware Test.I've since installed a new SSD and aftermarket RAM. The computer appears to be functioning normally (I'm typing this post on it), but I'd like to run the full hardware test to verify everything is OK.But I can't seem to get it to load into the hardware test. I've tried holding down D before pressing the power button on as well as right before the grey screen comes up. I'm confused because I've done this before without any problems.Is there something obvious I'm doing wrong or is there a way I can check for problems that would stop the AHT from starting?Additional info by @gentmatt:The last time I have performed the Apple Hardware Test, my MacBook Pro was running 10.7.2.

As of today, I'm running 10.7.3.The AHT loaded even after I had installed my custom SSD and RAM. But not this time. I suppose AHT has some uses, but mostly I just want the time back I spent trying to use it and then trying to see what the messages mean if it actually finds something (or dealing with the occasional false positive result.) Or what @DanBarrett said.ï¿½ bmike ï¿½ Dec 6 '12 at 2:031 I'll just leave it here, cause that's what helped me in the long run.

I tried it all, D, cmd-D, option-D, nothing worked, until I stumbled on this link: github.com/upekkha/AppleHardwareTest. After installing missing AHT files, just pressing D worked on my MacPro5,1.ï¿½ favoretti May 27 '15 at 5:16 Pressing ?+ D right after pressing the power button and before the gray screen appears works on my late-2011 15" MBP.

This forces an internet-based hardware test, which will work even if you've lost the the local hardware test software. (It will probably work over WiFi, but you have more chance of success with ethernet.) Same thing here (similar model MBP, same mods).

Learned that Option+D does the trick. However, if you get what I see, the AHT fires up and then says that it doesn't support this model of machine. No funny business, it's an Apple MBP (no hackintosh here), but I added a OCZ Vertex 3 and I've tried pre-8GB RAM kit (stock) and post, no difference. I get this exact same issue: "AHT does not support this machine." I think this means you're supposed to run apple diagnostics, but for some reason have AHT installed instead.ï¿½ Zach Mar 10 '14 at 18:19 Option-D worked for me as well on an early 2011 MBP 17 inch.

I've got after sales RAM and a Samsung 840 512 GB SSD in there and had not trouble getting to Apple Hardware Test.ï¿½ Foliovision Aug 28 at 20:09 Click on your embedded link again - the answer is just beyond the instructions for the "normal" startup method that you've been unsuccessful with:Additional InformationApple Hardware Test is included on the DVDs that are shipped with some Macintosh computers.

If the copy on your hard drive becomes unavailable, use the DVDs to run Apple Hardware Test.That should get you going.If you are running Lion and do not have install DVDs, try re-installing your old RAM (assuming you have it) and running AHT. I would bet that many people have inadvertently erased their HD based diagnostics without realizing it.

Thanks for pointing out the need to use the original media when the expected keys are not summoning AHT at boot.ï¿½ bmike ï¿½ Nov 12 '12 at 12:52 I have an early 2011 Macbook Pro 13", which I first replaced the hard drive (totally blank and repartitioned), then installed Mountain Lion, then upgraded to Mavericks.There appear to be two parts to the problem:1) Swapping out a raw hard drive causes the loss of a hidden diagnostics/recovery partition (that I never bothered to look for, and which doesn't appear to be visible using Disk Utility.2) The Apple KB article for Apple Hardware Test - https://support.apple.com/en-us/HT201257 - appears to be incorrect.

The correct sequence to invoke the AHT is:OPTION-D during a restart.Performing a restart and holding OPTION-D eventually produced a "Internet Recovery" screen, and then automatically started the AHT by itself (the quaint, OS9-styled screen). The Apple KB article is inaccurate.

After many unsuccessful attempts to launch the Apple Hardware Test on my MacBook Pro Early 2011 15",I discovered you need to hold Command + D during startup, not just I ran into similar situation with my mid 2011 mac-mini (with non mac keyboard/mouse & aftermarket updated RAM).

After pressing 'D' at startup it searches for internet, eventually asking to select wi-fi connection (no available connections displayed though). There's an option to specify wi-fi access point name & password but for me after putting the credentials the wait icon just kept revolving.Thankfully, I got it working using the ethHow to check for Hardware issues with your Mac Computerand perform the Apple Hardware test.Link for Error Codeshttps://support.apple.com/en-us/HT203747Using the Apple Hardware Test Over the InternetThe error codesUsing the Apple Hardware Test Over the InternetIf the test determines there is an error with your Mac computer, It will display an error code similar to this:4SNS/1/1/4000000 TL0P-130Here are what some of those errors mean4ETH: Ethernet controller4IRP: Main Logic board4MLB: Logic board controller4PRC: Processor4HDD: Hard disk4MHD: External disk4YDC: Video card4SNS: System sensor4MOT: Fan motor4MEM: Memory module4AIR: AirPort wireless cardA: Ambient air sensorB: BatteryC: Central processors (CPU)D: DC (direct current)e: PCI-express slotF: FireWire portG: Graphics processor (GPU)H: Hard diskh: Heat pipe (heat sink)L: LCD displayM: Memory or memory riser boardsm: Misc.

The technology has changed over the years, and the procedure is determined by how old your Mac is.________________________There a many ways a problem can crop up on your Mac. It could be a corrupted or failing boot hard disk or SSD, a flaky peripheral or a damaged or conflicted OS This article is restricted to the case where you suspect something is wrong with the very Mac itself.The first step is to determine the OS version and year your Mac was introduced.

One way to do this is to use Apple Menu > About This Mac. (If the introduction date for the product isn't specified, you can use a great app called Mactracker to convert a model number to an introduction date.)The first applicable document here is Apple support doc #PH18765.

In summary, as Apple states it:ï¿½ If your Mac is from 2013 or later, use Apple Diagnostics, which is built into your Mac.ï¿½ If your Mac is from 2012 or earlier and has OS X v10.8.4 or later, use Apple Hardware Test, which is built into your Mac.ï¿½ If your Mac is from 2012 or earlier and has OS X v10.8.4 or earlier, use the system software disc or USB flash drive that came with your Mac.For this how-to, I'll discuss Macs introduced in June 2013 or later and the Apple Diagnostics.Apple DiagnosticsThe Apple Diagnostics has detailed steps on how to shut down your Mac, which peripherals to disconnect, and how to hold down the D key at boot.

Note that there is no prefix key used here. Hold down just the D key right after you hear the startup chime.Note that if you leave the Ethernet cable plugged in and boot with OPTION + D, you can do some extra things, such as access your support and service options and contact Apple support.You should review this Apple Diagnistics page and even print it so you have a handy reference during the testing.

Especially useful are the keyboard shortcuts that are available.After booting, you'll see a black screen with a progress bar when the Apple Diagnostics start.The test takes only a few minutes.

When it's done, you see a notice with error Reference codes that describe the likely problem. Apple has an extensive page of error Reference codes that describe the problem(s) found, if any.Test complete and Hardware test macbook pro 2012 code provided.If you get the code ADP000, "No issues found," you can reconnect your peripherals, reboot and look for the trouble elsewhere.
