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.

You can buy and install the hard drive you want to. However, on Late 2009 and newer iMacs the temperature sensor is in the hard drive, so if you replace it with a hard drive that has not got a temperature sensor you will have serious fan problems.
You have got an Early 2009 iMac, so do not worry about this. You can buy a hard drive at OWC > http://eshop.macsales.com/shop/hard-drives/3.5-SerialATA/ Follow these steps > http://www.ifixit.com/Guide/iMac+Intel+24-Inch+EMC+2267+Hard+Drive+Replacement/9 028

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?

Imac wont start after electricity went off, no power surge. Apple Hardware Test ,no trouble found, please can anyone help,thanks ,Andy

Hi, please can anyoner help. I had a power cut at home and went to switch the imac back on and all i can get is a grey screen, a chime and a circle going around but no blue screen when I start up .I have tried pressing the power button for ten seconds with it switched off .Tried installing back up discs and after about an hour it comes up with an error that caused installation to fail and to contact the software manufacturer, tried again and the same happened. Tried apple hardware test and test results say no trouble found so am trying the extended test .any help would be great, thanks,Andy.

Try resetting the smc and pram.
To reset the smc
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.
To reset pram
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Apple hardware test..i dont know what this message means..please help!!

hi all..i really need your help. i have been having serious problems with my g4. it has been telling me to restart it while using most of the programs that come with installation. sometimes black lines with wording comes across the screen forcing me to shut it down. now all the programs are quitting one right after the other. i have reinstalled the system. i have no added memory installed...jsut the 256mb standard. tonight i ran an apple hardware test and i got this message. "memory- error detected error code 2mem/3/4:dimmo/built in" what does this mean? do i need more memory and if so where do i get this? thanks so much!

Based on that information the built in RAM has failed. What you have been seeing is a Kernel Panic. Sadly since it is the built in RAM, adding more memory wont help, not that you cannot doing it, but I don't think it will stop the Kernel Panics. Bad RAM causes OSX problems, namely Kernel Panics so until the problem with the built in RAM is dealt with this will continue to take place. Being built in RAM, that means you'll most likely need a new logicboard. You will have to get your machine repaired if you wish to continue using it.

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.

What are the meanings of Apple Hardware Test error codes 4m0t/4/40000003:hdd-1300 and 4m0t/4/40000003:hdd-1308?

what are the meanings of Apple Hardware Test error codes 4m0t/4/40000003:hdd-1300 and 4m0t/4/40000003:hdd-1308?

Thanks - Even though I'm years out of warranty I got chat help from Apple (I said they should help me since the codes aren't published.) We covered three different questions, and although I didn't get a specific decoding of the error code, I got confirmation of what other comments here imply - it might have helped that I indicated I'd already been here - and useful links to how to do back ups, including to CD(s). (I don't have a lot of data on this computer yet)
Now I need to figure out how to decide how hot-to-the-touch is "too hot" for the metal frame at the top of the iMac to decide whether I'm getting adequate fan performance or insufficient. While chatting I initially reported it was cool at the bottom and warm at the top. Apple hadn't asked, but their response prompted me to feel it again, and I'd say the top was hot, not warm - I updated but Apple didn't comment further except to conclude after addressing the other questions that I should take it in for further assessment - don't really want to bother with that.

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!

How do I run Apple Hardware Test on a 2012 MacBook Air with 10.8.4?

Hello everyone,
I am trying to run Apple Hardware Test on a mid-2012 MacBook Air with 10.8.4 installed. Whenever I restart and hold the letter D my computer goes into internet recovery mode and asks me to connect to Wifi... Please help, thanks!

Using Apple Hardware Test on computers with OS X 10.7 or later
Mac NoteBook and Desktop computers shipping with OS X 10.7 or later have a partition on the hard drive or flash storage that contains AHT. To start AHT on these computers please follow these instructions:
Press the power button to turn on your computer.
Press and hold the D key before the gray startup screen appears.
It takes a minute or so for AHT to start up and inspect your hardware configuration. While this is taking place, an icon appears on the screen:
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.
The AHT console appears. You can choose which sort of test or tests to perform:
To perform all of the basic tests, click the Test button or press the "T" key or the Return key.
To perform a more thorough diagnostic test, select the "Perform extended testing" checkbox under the Test button before you click the Test button.
Note: Your test results will appear in the window in the bottom-right of the console.To exit AHT, click Restart or Shut Down at the bottom of the window.
Some Macintosh computers that shipped with OS X 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.
The Mac NoteBook and Desktop computers listed in Computers that can be upgraded to use OS X Internet Recovery will require a firmware in order to support the Internet version of AHT. Without this update you may see the behavior discussed in this article.

The Apple Hardware Test error indicates a RAM issue. Install the original RAM and see if that improves the situation.
Also these items may perhaps be conributing causes:
TrustedData.driver.VendorSpecificType00 1.7.0
.drobo.SCSI.ThunderBolt 1.1 [66012]
.kromtech.kext.Firewall 2.3.6

Apple Hardware Test problems

Hi All. I have a very weird problem here, as I can't get the Apple Hardware Test to start on my late 2008, 2.66 MBP15 inch model# MC026LL/A (released early 2009 as a quiet upgrade from 2.53). Here's the story:
I opened up my machine as usual one morning, and the optical drive made a very weird noise I never heard before. So I decided to run the Apple Hardware Test (AHT) to see if anything was amiss. Well, I inserted the second install disk, held down the "d" key, and restarted the machine. It began to boot into the hardware test, but just after the AHT screen appears the computer just shut down. This happens every time I try to run the AHT.
I went to an Apple Store while I was on holiday in Brisbane (they don't have one here in Adelaide), and the genius said it was likely a bad optical drive. Well, I returned to Adelaide last week and had the local Apple Authorized store replace the optical drive. Tried to run AHT once again, and the same problem persists. So the original problem wasn't with the optical drive.
I thought maybe I accidentally used the startup disks for my wife's late 2008 15inch, 2.4, MBP (the one actually released in late 2008). I've looked around for the other sets of disks and can't find them. So here's what I'm asking help for: can someone who owns a 15inch MBP 2.66 15-inch (released in early 2009, model# MC026LL/A ) please tell me what the part # is for their set of install disks? It is written on the plastic sleeves of the install disks. And, could this person please tell which version of AHT is written on the disk itself? The set I have (which I think might be my wife's) has AHT version 3A158.
Might this be the problem, or should my computer still be able to run the hardware test using my wife's disks? I know they are both technically late-2008 15inch unibody MBPs, but I think my 2.66 (again, quietly updated and released in early 2009) might require a different AHT version, which would explain my inability to run the test. If not, what might be causing my computer to not run the AHT? I tried reinstalling OS X to no avail.
Thanks for all of your help!

I think I share your skepticism--if your Mac was shipped with the later version of the OS, you should not have been able to do a clean install with discs of an earlier version. It looks like some machines originally shipped with OS X v. 10.5.5 and others with OS X v. 10.5.6. I don't remember just when 10.5.6 came out.
Your two machines are likely very similar in build, and maybe similar enough for the OS to install. It may be that the AHT is specifically designed for the hardware in each machine, and that would be a bit different.
As someone else said in another thread, there ought to be a tutorial on how to keep track of the original install discs since they are always getting lost. Maybe a secure note in the keychain or something like that.
Out of curiosity, does the AHT work on your wife's machine? If not, there could be a problem with the install disc itself, and if so, you might be able to get a free replacement under warranty.
Good luck!

Apple Hardware Test error 4SNS/1/40000001:ID0R-0.000 on Retina MBP

Getting the above error on my 3-day old retina MBP with 16gb RAM and 768GB flash storage. I had loaded Chrome, Firefox, VMWare Fusion, Office 2011, and all the Apple updates as of 7/3/12.
My issue may be related to similar issues I've seen on these boards, relating to sleep or wakeup causing the intermittent crash. Machine has also crashed (kernel panic) 2 times. Genius Bar employee downplayed the AHT altogether, saying it's a false positive since his more advanced tool reported no errors. They then kept it for a day, to run a "loop test," which also came back with no errors. Then, because apparently it is easier to re-load the OS rather than actually diagnose the issue, they re-loaded my OS clean. (Yay, now I can re-load all my apps, copy 200GB data back on, and THEN we'll see that it is a hardware problem.)
Tomorrow I'll pick it up from Apple and run the AHT again. If it errors out again, I'm not sure what to do...

One note I had neglected to mention is that the bar/band immediately above the keyboard gets very, very hot. Yes, I know that is where the fans are. However, all 12 of the MBP's at the Apple store did not have this extra-hot band, and those are on all day. My little Safari & Mail apps should not cause an overheat situation, on a functioning machine. Apple blamed Google Chrome for the crashes, downplayed the overheating, and downplayed the AHT results.
Update: I went to the Apple store today and took a look at the notebook. They ran their tests, had re-loaded the OS, and performed an undisclosed hardware repair. (They were helpful but vague as to what the actually did on the machine, hardware-wise.) They said their advanced tools & extended Loop Test did not indicate any errors or problems. While still at the store, I ran another quick test with the Apple Hardware Test, which came back with the same 4SNS error as mentioned above. I asked for a refund, which they approved (except they said I have to come back Monday since I bought the machine from Apple Business.)
When I got home, I ran an extended test with the Apple Hardware Test and got a *diffferent* error this time: 4HDD/11/40000000:SATA(0,0).
It's seems strange to me that the AHT shows 2 different errors, and yet the Genius' "advanced " tools find no errors. Thankfully, I will return this one (eventually) get a new unit. Thanks to everyone for helping. --Peter

Using Apple Hardware Test?

Hi, I need some assistance.
I've got a MacBook Pro from 2011. That have some hardware, I'm sure. Please see this post. https://discussions.apple.com/thread/6029708
So I'm trying to use Apple Hardware Test. http://support.apple.com/kb/HT1509?viewlocale=en_US
But I can't make it work. And I've read the instruction for using the Apple Diagnostics test as well. http://support.apple.com/kb/HT5781?viewlocale=en_US
And it seems to me to be exact same approach.
Using Apple Hardware Test on computers with OS X 10.7 or later
1. Press the power button to turn on your computer.
2. Press and hold the D key before the gray startup screen appears.
3. It takes a minute or so for AHT to start up and inspect your hardware configuration. While this is taking place, an icon appears on the screen...
To start Apple Diagnostics:
Turn off your computer if it is on by choosing Shut Down from the Apple () menu.
Press the power button to turn on your computer.
Immediately press and hold the D key until Apple Diagnostics begins.
If you previously selected a language for” the computer, a "Checking your Mac" screen will appear in that language.
Can anyone instruct help me? I've tried using 25 times enabling the AHT. But the little icon never shows. I just get the regular login screen after some time.
MacBook Pro early 2011.
OS X 10.9.2

Sweet, OGELTHORPE
That worked! Apple own instructions are really not impressive. Haha. ****.
