Kernel Panics, Sudden Logout and Apple Hardware Test

Hello,
I have been experiencing Kernel Panics and Sudden logouts twice a week. I thought it was strange, because my boss just bought me the MacMini with 8gb RAM preinstalled.
I want to solve the problem, but I don't want to send my machine to support in vain.(because the MacMini is actually owned by the institution I work in, and those things take time).
So I ran some diagnoses I heard about on the internet, but I don't know what they mean, or what I should do with it.
I made two kind of diagnoses:
I tried to run Quick Apple Hardware Test.
I tried to run Mac version of memtest in single-user mode.
I made both diagnoses with each memory separatedly, in every slot combination possible, and both memories together.
Everytime I tested both memories together, AHT froze while testing memory, and memtest resulted in failures.
Everytime I tested a memory module separatedly, memtest and AHT gave no errors.
Is there any explanation for my Mac Mini not like my both memory modules together?
I updated OS X to 10.7.3 with combo update, and FileVault(don't know it makes any difference).
I made all tests with no peripherals other than a DVI monitor on HDMI out, a Magic Mouse, and a Apple (wired) Keyboard.
What should I do?
Should I send it to support and spend my next month without a machine?

If you're able to boot, launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.
Select the most recent panic log under System Diagnostic Reports. Post the contents — the text, please, not a screenshot. For privacy’s sake, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post "shutdownStall" or "hang" reports.
If you can't boot in the usual way, try a safe boot. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Safe mode is slower than normal, and some things won’t work at all.

VRAM failed Tech Tool deluxe and Apple hardware test

My G5 (isight) keeps 'freezing' so I ran the Tech Tool and Apple hardware test and they both say that my VRAM 'failed'.
The hardware test gave an error code2ATI/I/4: 113-xxxxx-113
How big is this to fix? I've started up from the install disk and the disc utility said the Hard Drive was fine. ny suggestions would be really useful.
Thanks
Andrew

Andrew, I would suggest you call Apple back and tell them that things are not ok, if you erased the drive, it should have repaired any bad sectors, something is not right. If you have Apple Care (I hope you do), insist that someone test your machine. Be sure to make a full backup before you take it in, I use SuperDuper!.
Good luck and please post back,

Disk repair and Apple Hardware Test says HD has no problem but grey screen still persists on MBP

5 days ago while on vacation, my MBP just froze with the grey screen, apple logo and spinning gear.
I performed all that was instructed on the following discussions:
http://support.apple.com/kb/TS2570
except Archive and Install installation of MAC OS X and Erase and Install MAC OS X since I was able to save my files in my husband's MBP via Firewire Target Disk Mode. At this point, I am still apprehensive in erasing my files and installing again the MAC OS X.
When I did the Disk Repair under the Disk utilities, it says that my Mac Os X is ok. (It also said ok when I did the fsck -fy when I till did not have my CD when I was on vacation)
I also tried the Apple Hardware Test (AHT) to further l test the hardware of my MBP and performed an extended checking and after an hour, its says that my HD has no problem.
Yet, after all these, when I restart my computer, it still has the grey screen with apple logo and spinning wheel!
Can anyone tell me what else can I do??? Appreciate any help!

I like the free demo of SuperDuper to make clones. It's free, Leopard and Snow ready and is easy to use. If you buy the full version you can do incremental backups.
You should use Disk Utility to do a Disk Repair, as shown in this link, booted up on your install disk, before you make a clone of it. I use DiskWarrior for that instead.
I then partition my external disk, in Disk Utility, with a partition that is the same size , actually a tad bigger, as my system disk. I then use SuperDuper to clone my system disk over to that partition.
With a clone on an external FireWire drive (USB drives are not bootable on PPC Macs but are on some Intel Macs) you can bootup on it to do your repairs, on the main drive, or just run your Mac anytime you have trouble with your main drive.
That's why I like clones better then Time Machine. You can just bootup on them and use your Mac.
On the DiskWarrior thing, I use DW once a month to try and catch errors in my system from getting too far out of hand. It has repaired every little and big issue I have ever had with my three Macs.
And I have had times when Disk Utility's Disk Repair says everything's fine but my system was still having issues. Disk Utility, in my experience, cannot be totally relied on to find and report all issues. It just isn't robust enough.
I run DiskWarrior, it does find errors, repairs them and I'm back in business. I swear by it!

What is the difference between Apple Diagnostic test and Apple hardware test?

I've just been wondering if one is better than the other? My mac shipped with apple hardware test, and I'm curious if the newer Apple Diagnostics is better

Apple Diagnostics is better, but no Mac model can use both it and the Apple Hardware Test.

MacBook Air Late 2010 and Apple Hardware Test

I just bought a second hand MacBook Air Late 2010, 13 inches, 2.13 Core 2Duo. Everything works great, system re-installed after erasing the HD ( Mountain Lion) Internet recovery works great, all is ok.
The only thing that I can't work out how to get is AHT. I tried holding down D at the start but nothing. Holdind down D and Alt takes me to the Internet Recovery harware test, but when I try to run it, it comes out that the machine is not supported. I read that to be able to use it, I needed to dowload a firmware update. And so I did. But when I tried to install it it came out that it was not going to work on my system ( bare in mind that I can access and use Internet Recovery)
What Am I doing wrong?
I'm not too bothered about being able to use AHT at the moment, but there will be time when I will need to.
All the help will be appreciated.

It has to be available. It is the only way to restore that system back to as shipped from factory specs and reinstall the ilife apps. In your situation since you have another mac and a valid license for mountain lion and you have a air of a newer model year that can use the internet recovery system you were able to install a version of os x. But if you didn't have a license and that air was just one revision prior to that model year you would be stuck with a computer and no working os on it or no valid os on it.
Basically when anyone is selling an mac computer that computer should be wiped and the original os x version reinstalled. To do that on system older then late 2011, or some of the early 2011 models, you need the original apple supplied reinstall media. Whether that is dvds or a usb thumb drive. Otherwise the seller is selling pirated software and the buyer has no way of updating or upgrading that mac computer.

Apple Hardware Test DISABLED by update?

Maybe I'm jumping to conclusions. Is there a way to get this feature working again?
MacBook (Late 2007) has a cool undocumented feature... hold the D key at startup, and Apple Hardware Test (AHT) launches--WITHOUT THE DVD. Yes, it's built-in.
Sadly, this feature seems to have been disabled by a recent update... possibly the Keyboard Firmware Update
Sigh. Now I have to drag out my clunky old DISC just to quick check TBOT
see other posts here regarding 4SNS/1/40000001:TBOT error in AHT

Try starting the AHT with the OPTION + D keys.
You should be able to use the #2 install disk. It has the AHT instructions on it.
Ciao.

Apple Hardware Test Error: 4SNS/1/40000001: IDOR-0.958 what's wrong?

Hello
i swapped SSD in MBA A1369 to an OWC 256GB, it worked well since 2 months until yesterday.
When I opened screen to wake up, it showed only blinking folder with question mark so it couldn't find startup volume.
SSD is invisible in Disk utilities and Apple Hardware Test shows: 4SNS/1/40000001: IDOR-0.958.
I don't know what this error means, is it any way to repair it on my own?
If not, memory seller will exchange item, but I'm asking you guys, before shipping.
Thanks in advance

Ask and ye shall receive reilogix...

Your machine is absolutely fine. Run the test again with your power connected.

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

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.

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.

I have Mac Pro 2010 model and it's giving heavy fan noise,so run the Apple hardware test but it's showing the Error: 4SMC 1 40000000 please help me in this issue.

How do I run the Apple Hardware Test? Its not on my DVD and the Internet-connected version tells me my computer isn't supported!

I have a mini - late 2010 2.4 ghz core 2 duo - that just started black-screen crashing and failing to wake from sleep. Up to a few dasy ago this was a really bulletproof machine! When trying to restart it afer a crash it sometimes emits three weak beeps (sometimes more).
Apart from spontaneous motherboard failure (??) I can only guess that the RAM failed (an 8GB upgrade installed last fall). I pulled one 4GB RAM board and the mini booted again! But it still sometimes fails to wake from sleep, and sometimes give the three beeps. I've run REMBER (a memory test program) on one of the RAM boards and it passes the test. My next step is to test the second one -- but whether it passes or fails there seems to be something else going on.
I'd love to try the Apple Hardware Test but:
- pressing D on startup has no effect (even when starting up with the original install DVD)
- pressing Option-D brings up an Internet-loading screen that brings up a Hardware Test screen then tells me my computer is not supported.
Is the AHT simply unavailable for my model of Mac? And/or is there any way to test my hardware?

The 2010 Mac Mini's came with a 2 DVD set, a Mac OS X Install DVD (22691-6657-A) and an Application DVD (22691-6658 -A). The Apple Hardware Test is on the Application DVD (22691-6658-A).

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.

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!)?

HT202731 What should I do next when using the apple hardware test and it will not complete. It always gets frozen when 56 seconds of testing has passed?

MY MacBook pro will not boot up correctly. When switched on a grey screen appears and a flashing question mark box.after researching I have been able to try to complete an apple hardware test by holding the D key when switched on. Unfotunately this text will not complete. Every time I try and perform this text it sticks after 56 seconds of testing and does nothing rlse. Resulting in my having to force shut down.
I know do not know what else I can do to try and solve my problem.
Any help would be grately appreciated.
Thanks.

I would install a new HDD, format it and install the OSX. Then I would connect the old HDD via USB and see if I can access the files that are on it.
If no success and if the data is important, look for recovery software on the Internet. Most have a trial that will tell you the possibilities for retrieving data but then you will have to pay for the software.
The last option is employing a professional data retrieval service. That will be expensive with no guarantee of results.
Ciao.
