HT201257 I have a slow boot up, so I wanted to run Apple Hardware Test. AHT never starts

I have a slow boot up, so I wanted to run Apple Hardware Test.
AHT never starts based on http://support.apple.com/kb/HT1509 but AHT does not come up. Tried it 20 times, no success. I have iMac 2011 w/ Lion. What should I do.

Hi Titan,
My system didn came with the disk. I have used disk utility to repair the disk, because it showed a boot sector problem during disk verification process. I started disk utility using Cmd+R at startup. The problem was fixed. Not the disk verifies without error.
However, the initial gery screen at startup still take more than two minutes after with the apple icon appears.
Thanks.

Error when booting from Apple Hardware Test (AHT) CD

Just downloaded AHT 1.2.6 from here for my 2nd-hand Power Mac.
Burned it to CD with Disk Utility on my iBook, booted from it on the Power Mac, and received the following message after the "loading..." splash screen:
invalid memory access at %SRR0: 00034870 %SRR1: 00003030
This left me at a command prompt, from which I chose to shut down the Mac.
My Mac version is PowerMac3,6 4.4.7f1. Is this error down to using an incorrect AHT CD, or something fundamentally wrong with my RAM? I did test my RAM after purchase with Rember and possibly also with Tech Tool Pro 4.5.3 - no errors reported then.
SiR G.
EDIT: The Power Mac now has its original graphics card installed, not the ATI Radeon 9800 Pro; however, it still has the Sonnet card in place as the boot disk runs from this.

Hi,
You have the same problem as I, but I also noticed your firmware is a little off. The absolute last firmware update should have given you: "4.4.8f2". Here, have a look at mine.
Machine Name: Power Mac G4
Machine Model: PowerMac3,6

Yeah, I get the same problem as well with the AHT CD, strange as it seems. I tried removing DDR chips one at a time to find the culprit. It seems that I have been unable to figure out why it goes to the open firmware command line and prints: invalid memory access at %SRR0:00034870 %SRR1: 00003030. I ran memtestosx with applejack and although it took hours for it to complete, it gave me fantastic reports of all my memory functioning normally. I do notice the following with my memory:

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.

2008 iMac running beautifully untill recently. Screen glitches and freezing. Apple Hardware test showed error code 4MOT/2/40000004:ADD and I have not seen others with this code. Guessing it is a fan issue based on the ODD and HDD error codes

computer felt hot and while running apple hardware test the screen glitches covered the screen and it froze. Now computer wont boot up. Again AHT code is 4MOT/2/40000004:ADD and I have just seen ODD and HDD codes discussed on other threads.Those were hardrive or superdrive fans, so I am guessing this is a fan issue and then it fried by graphics card. Any help as to whether this is game over or worth repairing would be very appreciated.

You need to take it to your local Apple Store or AASP for a professional evaluation. Apple does not publish the codes from AHT, you can Google the code you got and see if you can determine what it means however the best method is to let a pro handle it.

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

HT201257 I just bought an imac in september 2012. And i just find out that my microphone is not working. So i did an apple hardware test and with no problems found? I have sound but no one can hear me, not even the computer. Should i bring it back to

I just bought an imac in september 2012. And i just find out that my microphone is not working. So i did an apple hardware test and with no problems found? I have sound but no one can hear me, not even the computer. Should i bring it back to the store

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.

Can't boot off Apple Hardware Test disk

Can anyone suggest why my laptop won't boot off of its Apple Hardware Test disk anymore? I have not tried it in years, but want to try now. I have the original, and a copy I made years ago, and neither will boot. I can select them at startup disks in that preference pane in OSX, but then it fails to find it, and boots into OSX. I can boot into OS9 on the hard drive. I was able to partially boot off of a different AHT disk from my 12" Albook G4, but it gave the message that I can't use that disk since it is not meant for the Tibook. One idea is that TechTool tells me that "macintosh startup file was absent", and the Help file states:
"The Startup file is intended for use by systems that do not have built-in ROM support for booting from HFS Extended volumes. The first eight extents of the Startup File are stored in the Volume Header. This makes them easy to locate and read into memory. This file contains information used by the computer’s ROM to determine what program will boot the computer. In almost every case, this will be configured to point to the preferred System."
But it does not tell me how to restore this Startup file.
-how can i get my startup file back?
-my computer boots fine off the hard drive, so is this file used only to boot off a CD?
-any ideas why i can't boot off my AHT CD?

Hi, t. (That alias of yours sure is a mouthful.) I think in your shoes I would pose the question to the tech support people at Micromat (TechTool's developer). It's their error message, after all, and they should be able to explain it to you in as much detail as you need. Perhaps they'll shed some light on the original problem in the process.

MacBook won't boot after trying to repair with Disk Utility. Cannot boot in Safe Mode. Just powers down after about 5 minutes. Apple Hardware Test says error 4SNS/1/40000001:IG0C-0.265 But I cannot find anything on the net about it. MacBook 4,1 Intel.

Hello Everyone,
I am in dire need of assistance I am hoping someone could provide. I have a MacBook 4,1 with Intel Core 2 Duo processor 4GB Ram. It is taking over 10 minutes to boot up past the gray apple screen when I turn it on. First I cleared the PRam (?) then I checked the disk using Disk Utility Verify, and it said the disk needed repairs. So I ran the disk repair and it said it was unable to fix the errors on the HD.
I did a little research and tried booting into the Single User mode, then running /sbin/fsck -fy. It said that it found errors but could not fix them. I ran it two more times as suggested and got the same result each time. I then tried rebooting and now instead of taking 10 minutes to boot up, it takes about 5 minutes on the gray apple screen and then just turns off. I started in Verbose mode to try to troubleshoot the error and it appears the last thing to come across the screen before power down is a message "Apple Yukon 2: RxRingSize <= 1024....etc".
I decided next I would run the Apple Hardware Tester. The test came back with an error code "4SNS/1/40000001:IG0C-0.265". I am very good at searching the web but I could not find any errors that had the IG0C or IGOC or any combination at the end, but plenty of 4SNS/1/40000000(1) errors with different endings. From what I can tell people are saying anything with 4SNS/1/4000000 is a logic board failure, but this computer was literally just booting this morning until I did the /sbin/fsck -fy.
Any suggestions are welcome and appreciated.
Thank you for your time.

You've a couple of issues .... when Disk Utility tells you it can't repair a drive, if the error is a soft error, like an invalid tree or node, Disk Warrior (or TechTool Pro) can handle it. However, if Disk Warrior (or TechTool Pro) can't handle it, you can erase and write zero's to the hard drive and restore to it, or you can buy a new hard drive. Sometimes running SMART Utility can provide additional insight into the health of the hard drive.
THe 4SNS error is a sensor error. You could install iStat Pro to see if something is indeed getting too hot or remaining room temp or less. You may need to take it into an Apple shop so they can use their thermal diagnostics to test and isolate it further.

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:

Won't Boot to Apple Hardware Test or accept Boot Commands

Hi All,
I would appreciate some help with this issue, I am trying to boot up to the Apple Hardware Test on my Install Disk 1 that shipped with my MacBook Pro 2.4GHz Model #A1226 ordered new with 4 gigs of memory (around Aug. 2007). I am currently running 10.5.6 and the install disk of course contains the Tiger OS. I have nothing plugging into my computer, other than the Power Adapter. I have the proper install disk inserted in the computer and am holding down the "d" key on my built in keyboard throughout startup, but it will not go to the AHT. It simply boots to the normal login screen for Leopard. In fact the only boot commands that I see any visible or audible confirmation that it has taken effect is the option key, taking me to selecting a Startup Manager and holding down the Power Button gives me a tone from the internal speaker after a few seconds.
Below are what I have tried with seemingly no effect:
"d"
"c"
"t"
Option-Command-"p"-"r" (no beeps)
Command-"v"
Command-"s"
Shift (not sure I should see or hear any confirmation, I don't have any login items set right now so I can't tell if it has any effect)
I have not tried an of the networked drive boot commands as I don't have any networked drives
The only way I have been able to boot from either the optical drive or another disk is either holding down the option key during boot up or selecting the drive from the startup manager in system preferences.
I can't seem to access the AHT an in any way. The reason I am trying to access it is because I have had a few weird intermittent problems that I can't put my finger on and would like to be able to rule hardware out.
I also just replaced my HD with a WD 320 gig drive after my original drive failed due to a physical error. I just restored my data, and all seems to be running well after a permissions repair and a disk repair while booted up on my install disk.
The intermittent problems I was talking about are very vague and rare so I is difficult to describe them other that just a hunch that something is still a bit off. One is the display, every once in a while, showing what looks like a massive bar code or UPC code on my screen. This is not like the bands with soft edges that seem to be a well documented issue with the early MBP but transparent lines of alternating width and brightness with hard edges. Again it looks just like a UPC code transposed on my screen. The other items are random freezing of the OS or the mouse and the fact that my keyboard does not respond to any but a few boot commands. Again all the things are either rare and intermittent or do not come up in daily use of my machine. But when taken together, seem to add up to the conclusion there is still some issue present (at least in my mind).
To recap my specific questions relate to not being able to run the Apple Hardware Test and many of the boot commands having no effect. If you can shed light on the other items mentioned, great!
Thank you!

At a guess, I would think this error code has to do with the video artifacts you are experiencing. You might try reseating all the cables to the display. If the position of the screen makes a difference, there may be damage to a cable, particularly where it goes through the hinge.
Apple is the keeper of the error codes. If you have access to an Apple Store, you could probably ask about this.
Don't know about the other intermittent problems. Does an external keyboard work? If so, there's likely a problem with the internal, maybe even again, a cable or connection.
You could also try creating a new use account and see if the keyboard and mouse problems persist. If not, there could be some sort of software corruption in your usual account. Ditto with the freezing.
Good luck!

Ugh/ kernal panics / apple hardware test will not boot / help

so my first thought is to replace all my memory and I even have some coming via OWC -- but it seems silly just to replace memory on a hunch and randomly. So I run rember and get an all cler on all my memory. Can this really be soo? So I think - try the Apple Hardware Test.
I hold down c key as 'puter is booting and I get command line screen that says
"invalid memory ascess at %srr0:ae0c0108
%srr1: 0c01086F
bad bus info crc-16"
than it tells me to type in mac-boot to boot --but it will not boot - the next screen just says command line ok
what should I do next
this machine has been acting up for over 6 months and its driving me nuts -- I bought the memory as a "quick fix" but now I am starting to have my doubts. It would be cool to know before I decide to install it so I can return it for my $ if my hunch is wrong --
help! and thanks!

I can give you some general advice about buying memory:
The question then becomes what if memtest passes it all... I couldn't complete the cloning of about 220 GB of files from one drive to another with the original MacWarehouse chips in place, but could when they were removed.
I have had quite a bit of experience testing memory, most of it grey market stuff that I salvage from trash cans and such like place. I have found some memory that worked perfectly and never gave me any problems. I have found some memory that gave me kernel panics. I have found some memory that are somewheres in between: they seem fine at first, and then when you start to run lots of apps or copy large files that's when the problems shows up, and the problems are subtle -- once in a while a task would randomly crash, but restarting the task would make it OK, etc., etc.
I've had a PC133 stick that repeatedly tested and passed on memtest until the 4th pass, then an error showed. After the error showed, there were lots of errors.
For my own use, I do not use any memory that fails memtest at all, since I am swimming in memory anyway. I usually test them overnight. Certainly when buying new memory I expect them not to fail memtest when run overnight (usually about 6-7 passes).
I'll use memory that fail occasionally in client stations that are not function critical, but my experience has been once you get some error in a memory chip, it gets worse with time.
I want to avoid if possible having the machine down for hours at a time to run memtest in Single User mode as it's serving up genealogy databases on 4 different domains, as well as static pages on 8 other domains as well as being my every day work-a-Mac.
If you're serious about hosting those domains, I suggest you buy a Mac Mini for your clientstation and let the server be the server.
sending CL3 chips maybe the Apple Hardware Test is expecting to see CL2.5 which is what the 3 chips I have to do work are.
CL3-PC3200 chips can pinch hit for CL2.5-PC2700 chips in some limited circumstances, but they were sending you CL3-PC2700 chips in place of CL2.5-PC2700 chips. I smell herring.
or are they really not the chips the label says they are?
Chips are sometimes mislabeled, due to operator error.

HT201257 Holding down "D" no longer starts Apple Hardware Test! Any idea what's happened and how I fix it? Or do I need to go to the Genius Bar? MacBook Pro with Lion Preinstalled.

I have a MacBook Pro with Lion Preinstalled, so AHT was present on the hard disc and worked when the product was new. One of the first things I did from new was run AHT and it worked fine. But now it doesn't start - instead the machine (eventually) boots into normal OS X.
Holding down "D" no longer starts Apple Hardware Test! Any idea what's happened and how I fix it? Or do I need to go to the Genius Bar?
Software Mac OS X Lion 10.7.3 (11D50b), if it makes any difference.
Any ideas?

Thanks. However, even with an internet connection that doesn't work for me - the machine just (after an extended delay) boots normally. It doesn't download.
Option-D works for an Internet-based AHT. However that only works with an internet connection. It doesn't seem to download it and install it - it needs internet every time.
Any idea how my local copy of AHT disappeared? I haven't repartitioned the drive or knowingly deleted anything. And how do I reinstate it (because if you need AHT your hardware problems may preclude internet access!)?

HT201257 Apple Hardware Test

will I lose any information on my computer if i run the Hardware Test?

The AHT doesn't fix anything. It merely checks specific hardware in the computer to be sure there isn't a problem.
Did you have these lines on your screen while running the AHT? If you boot from your OS X installer DVD do you still get lines on the screen?

HT1918 hee guys how do u delete a creditcard from your apple id? in the summer a friend of mine connected his own creditcard details to my apple id now i want to disconnect that again but i have no idea how? i just want my own apple id without a creditcar

I own the movies and I want them to stay in my iTunes library basically forever.
But in both cases the file name no longer shows in the movie list, so I don't know how to re-download it from the Cloud.
iTunes prefs > Store > Show iTunes in the Cloud purchases.
This will show all your iTunes purchases in your library with a cloud icon down arrow. Click the icon to redownload or click on Play to stream without downloading.
Also see this , -> Download past purchases
and techncially, you don't "own" the movie, You simply have a license to use it.
Yet the first thing iTunes does when you hit the delete key is tell you that it will remove the movie forever from all devices and the library.
Actually, no it does not tell you that.
FYI: You should keep copies of all yoru iTnue spurahses as the labels/movie studios/copyright owners can pull their product at anytime and it won't be available to redownload.
