Does the Apple Hardware test come with Snow Leopard?

Does the Apple Hardware test come with my iMac 27" i7?
If so, how is this activated and is it used as a periodic test or only when a problem develops?
Thanks

The Hardware Test will be on the Install DVD(s) that comes with your iMac. With the correct DVD inserted, (re)start the iMac while pressing & holding the "D" key to start into the HT. Run it anytime you want to check the hardware.

Does the apple hardware test, test the optical drive?

I think my optical drive may have issues. Does the apple hardware test the optical drive?

No it doesn't.
What kind of issues are you having? Reading/writing? CDs/DVDs?

Installing Leopard server on the servers that only come with Snow Leopard

Has anyone ever "downgrade" - installing Leopard server on the servers that only come with Snow Leopard installer disc??? Is there anything special involved?? Or can I just pop in a Leopard Server installation disc from previous generation servers and procede?? These servers are going to be a part of Xsan. And with my previous horrible experience with Snow Leopard and Xsan, I am really trying to avoid going through that again... Thank you!

The general answer is yes. But the conditional answer is that you must have the original installation media from the Xserve model before it started shipping Snow Leopard exclusively. This means you would need to have bought an Xserve as recently as December to have the combo OS pack as I believe Apple stopped shipping Leopard around early January (although that might be on BTO models so if you got one from the channel it may still have the original media kit). You need to be mindful of the machine's Boot ROM version. The change of one digit can cause some issues with older installation media.
If you don't have recent media kits, you "should" be able to construct a functional OS by building on other hardware and patching up to 10.5.8. Then cloning it to the new unit.
And, you've peaked my interest. What specific issue have you had with 10.6 and Xsan?
Hope this helps

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.

When Lion officially comes out from the Mac App Store, I understand that I can just buy it from there. However, will the laptops have Lion automatically? Or does it come with Snow leopard still.

The ones sold that day will come with Snow Leopard most likely but they will be able to get a free upgrade to LIon if they apply within 30 days. Hardware coming through the supply chain from the day of the announcement will have Lion installed so it depends what stock people have to move before buyers see those.

Before you go through that trouble open About this Mac > More Info... > System Report > Audio and see if the system actually knows it has a microphone. Then you can look into Applications > Utilities > Audio MIDI Setup and see if the microphone is there, select it and make sure the sliders are set to full. Then in System Preferences look for Sound > Input and make sure it shows up there and the sliders are at least half way up. If none of that works do a
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.
then go through the process of looking for the microphone again as the reset may reenable the mic.

I really need help with the Apple Hardware Test!

I have been having problems with the computer freezing. The other night the only way I was able to start it up was to boot off the install disk. My brother being fairly savy with Macs helped me with this. Long story short, I uninstalled and reinstalled all of my non Mac programs. This happened three days ago. Everything seemed fine. Then tonight, same thing. My screen froze, and I shut it down. I couldn't access anything. I zapped the pram, and my user screen came on. When I tried to log in it froze again. Then it started just shutting off on it's own. Everytime I turn on the computer it shuts off. So then I tried holding down the shift key, then by accident, I held down the D key. I thought I remembered my brother doing this. Then the Apple Hardware Test screen came on, so I did the test. It said: A harware error is detected 4HD?11?40000004:SATA(0,0)
What does this mean and what do I do?

SATA would very likely mean your hard drive is failing or has failed. Do you have AppleCare?

Have the Mini's Serial# handy & call Apple Care, they usually have original replacement Discs available.

I was checking my diagnostics and i noticed that it said failed in the Apple Hardware Test please help.

Apple Hardware Test Stuck with white screen

hy every one..............
i am unable to start the apple hardware test ,i've done anything ,holding d at start up with inserted installation disk,also with holding c........
also inserted application cd....
apple logo appear and after some time with spinning wheel it stuck with white screen....What that means
please help me out....
what can i do???

If you are still using Snow Leopard -
Shut down your computer and disconnect all peripherals (keyboard & mouse if pertinent) from your computer. Now reboot.
If the Mac starts up normally, shut it down again and then plug in one of the peripherals (keyboard or mouse first) and start up your computer again. If it does so successfully repeat the process, adding one peripheral at a time until your Mac acts up. At that point, disconnect the last peripheral you added, reboot your Mac and search the peripheral vendor's website for an updated driver.
If no driver exists or the problem remain after installing the new driver, try a different cable or a different port on your Mac.
If none of the above works, again disconnect all peripherals from your Mac, hold down the "shift" key to start up in "Safe Boot" mode.
If the Mac starts up correctly, restart without pressing the "shift" key.
If your computer still does not start up properly, shut it down and restart it while holding down the Apple+Option-P-R keys; keep holding "all 4 keys" down until you hear the startup sound "twice."
If none of the above work Disconnect all peripherals from your computer. Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.
(If Disk Utility cannot repair, you will need a stronger utility (3rd party) - Diskwarrior or Techtool PRO)
Restart your computer when done.
Repair permissions after you reach the desktop-http://docs.info.apple.com/article.html?artnum=25751 and restart your computer.
Remove any 3rd party ram.
Reinstall Snow Leopard - This will install a "fresh" copy of Snow Leopard without archiving old system files but leaves the rest of your files in place.
If your computer is still under warranty or you have Apple Care, take full advantage of it by letting tech support deal with your problems. It's what you're paying them for.
Out of warranty - take the computer to an Apple store or an AASP. Whichever is more convenient for you.

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.

AHT is on the original OS X Install disc that came with the computer! Had you read the Apple Advice Letter I posted earlier you would have seen that.
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.

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.

G4 that will not boot from any disc EXCEPT the Apple Hardware Test CD

We have a DP 1ghz Quicksilver PowerMac G4 that will not boot from any disc EXCEPT the Apple Hardware Test CD that came with the machine.
We were in the process of installing 10.4 Tiger before placing it for sale.
The Mac was originally OSX Server 10.1 that we later converted to a worksation running 10.3 Panther.
It has 1 GB of memory, 80GB hardrive, 250MB Zip Drive and a Radeon 7500 video card.
Since this machine only has a CD-R drive and not a DVD-R, we installed Tiger using another Mac via Target Disk Mode. The installation process went well, but when I tried to reboot I got a Kernel Panic right after startup screen with the grey Apple logo.
On some reboots we get to the blue startup screen, others it stops at the grey Apple logo, others a black box like the a Kernel Panic - but with no text. Twice it went directly into Open Firmware.
We have done the following during our troubleshooting:
- Reseat RAM, Video Card, Hard Drive, Zip & CD-R connections
- Remove RAM 1 stick at a time and reboot
- Replace RAM with RAM from another working Quicksilver
- Replace Video Card with one from another working Quicksilver
- Zap PRAM
- Reset CUDA switch
- Unplug the MAC and remove everything (RAM, Battery, etc) for 30 minutes and try to reboot
- Tried booting from the Macintosh Server G4 Software Restore CD
- Tried booting from Mac OS X Server CD
- Tried booting from AppleCare Protection Plan CD with TechTool
- Tried booting from Diskwarrior CD
- Tried booting from an external FireWire drive with a disk image of Tiger OS Install
- Tried booting with the hard drive disconnected
The Mac WILL boot from the Apple Hardware Test CD and will pass ALL of the extended tests.

Conventional wisdom says that any Mac that will not boot up from a System/Install CD OS 9 or an Install CD Mac OS X, has a Hardware problem.
The diagnostic CD is a red herring because it uses a very primitive method of reading the CD, and so does not properly represent the machines general ability to read CDs.
I would look at the CD drive cables, etc, and see if another drive gives different results.
You have not mentioned using the Startup Manager (option key at Startup) to do any checking:

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
