! ! ! G4 Mirrored Door: stuck in Apple Hardware Test??

iWork'09 wouldn't install, so I thought I'd run Apple Hardware Test (never done that). I found the disc that came with my machine and rebooted. The first line was notice of +invalid memory access+, but I was asked to type "mac-boot", so I typed mac-boot. The next screen looks like this:
+invalid memory access at %SRR0:05610dc %SRR1:00003030+
ok

It's just sitting there like that. What am I supposed to do?
Thanks.

Will it boot in Safe Mode? See

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.

Can't get Apple Hardware Test to work

So I'm trying to run the Apple Hardware Test. I start the computer up and hold "D". It boots into OS X like a normal startup. So, I plug in the Ethernet and hold option-D to do the AHT from the Internet. It tells me "Apple Hardware Test does not support this machine".
So, I try to install the "iMac EFI Update 1.8" from http://support.apple.com/kb/DL1493 (which is for my iMac model, which is a iMac (Mid 2010)), but it says "This software is not supported on your system." I also tried the later version, v1.9, from http://support.apple.com/kb/DL1498 but it isn't for my iMac and so I get the same error.
So now I'm stuck. What should I do now?

Thanks that was it. It says AHT on the disk itself. I successfully ran it, and it found no problems ("No trouble found.") I ran the basic test only because I have 16 GB RAM, and so I imagine it would take a long time to run the extended—probably at least two hours? And I don't know what more that would find that the basic wouldn't?

Will Apple Hardware Test definitely detect RAM errors?

Hello,
Been having various problems with Leopard/MacBook. Someone suggested running Apple Hardware Test, which I did, in extended + looping mode all night (it cycled 6 times). The test turned up nothing. Can I take this to mean that whatever problems I am having are definitely software related? I am not familiar with the AHT, don't know exactly what it does, nor how I can interpret a "clean" result...
Many thanks for any advice/tips.

No indeed (just "Colin" is fine...)
My problems have mostly been documented by other people, and I have just been monitoring the discussions on these issues.
Specifically (at the risk of getting off-topic):
1) inconsistent shared server behaviour: I have 3 other macs at home - an iBook and a G4 MiniMac running Tiger, and a G4 tower, also running Leopard - and most of the time, the tower doesn't show up at all, but I can connect to it via CMD-K, the MiniMac shows up in the sidebar, but won't let me connect, and the iBook, when it is running, behaves normally. Oh, screen sharing doesn't work either: it tries connect but hangs (except for the iBook, which works). I could connect to all four quite normally after upgrading to 10.5.0, using the sidebar icons. Everything worked fine until sometime after the 10.5.1 update, when suddenly everything went pear-shaped. Nothing has changed in the configs of the other machines, and the iBook and the MiniMac are identical in terms of software config (but behave differently as regards this problem?!?)
Closing Airport and reopening it makes the icons reappear in the sidebar (all of them, G4 tower included), as does relaunching the Finder, but doesn't change the behaviour: I still can't connect. When I try to use the sidebar icon for the tower, it disappears (the icon...)
As far as I can tell, trying to operate shares from the G4 tower works as Apple intended (although I admit I have not exhaustively tested every option, as I don't have unlimited time...)
2) Lost my printer connections, both at work and at home. I managed to reestablish them at work, but I tried so many things that finally I'm not sure what actually worked. No dice at home (shared printer on the MiniMac... same problem as (1) I guess.)
3) the dreaded Keynote spontaneous reboot problem (I placed a reply about that last night here:
http://discussions.apple.com/message.jspa?messageID=6630702#6630702
4) diverse weird things, like
4a)iCal which had doubled all my events the last time I opened it. I had to manually delete one copy of every event I had entered, whereas I made these entries several weeks ago, and had consulted them many times... I'm thinking this is perhaps a result of the brutal reboots caused by (3)? Having deleted all the doubles, iCal seems to be behaving normally again.
4b)screen resolutions on my slave screen suddenly failing to select properly. I move my MacBook between two different external monitors, one at work, one at home, and their resolutions are different. Initially the MacBook had no trouble detecting and correctly setting the resolutions for the two screens, then suddenly my home screen went weird on me, and required a manual reset. Again, this was a once-off, and does not seem to be repeating (yet).
4c)sluggish performance with some apps that are normally quite snappy, like Firefox, which seems to hang a lot loading pages, Keynote (saving is often painfully slow), and indeed, trying to copy a 250Mb file from the tower to the MacBook via Airport (having connected using CMD-K) said it was going to take 33 hrs, which I thought was a bit rich...
4d) hot-swapping a usb pin for a keyboard+optical mouse receiver from the tower to the MacBook sometimes causes something inexplicable to happen to the MacBook's keyboard: both the Caps and the NumLock LEDs come on, and the keyboard has jumped into some config other than what it is normally in (French). I have not been able to determine what the keyboard actually thinks it is when this occurs (3 times now). The command keys (ctrl, alt, cmd) do not appear to work at all. Rebooting corrects it.
All up, pretty irritating, and a huge time waster, as you can well imagine. I stuck a bit of a rant on the discussions the other day in a moment of intense frustration, which got zapped by the moderators (probably not unreasonably!), but not before someone replied suggesting that it might be bad RAM, hence my questions here.

Is there a download for the Apple Hardware test 3A126?

Is there a download for the Apple Hardware test 3A126? I get a gray screen for several minutes until start up, Tried holding down the "D" key but no test, there is a disc stuck in the superdrive so I can't use the install DVD.

You can only run the Apple Hardware Test from the correct Disc that came with your system. see > Intel-based Macs: Using Apple Hardware Test
Have you tried the following > The ultimate guide to ejecting a stuck disc
or > Eject a stuck disk from your Mac DVD super drive to get the stuck disc out?

Apple Hardware Test (Extended) not progressing

After upgrading my white MacBook (13-inch, mid 2010) from Snow Leopard to Lion, i was getting Kernel Panics, maximum of 5 min after startup. So i decided to downgrade back to Snow Leopard.
I erased my hard disk, tried to install SL from the DVD that came with the MacBook, i got a Kernel Panic. I tried it for 6 times, all with the same result.
I made the Apple Hardware Test, it passed.
Now i'm trying the Apple Harware Test (Extended), it's been almost 6hrs and here's the status:
Testing Memory
No error messages
Pass Number: 1
Time: stuck on 2hr 15min 49sec
Progress Bar: about 13%
However the mouse is still responsive. Is it normal for the test to take this long.
Thanks
PS: i tried the option-commant P R before running this test, and i dont have any peripheral connected

I have had endless issues with kernel panics since Lion. Rolling back to SL won't save you, because the last couple of updates to SL added in the cause of the panics:
Some combination of multitouch trackpad drivers and the graphics card drivers.
So, what I've done, and it seems to work better ( I can use this POS laptop for more than an hour now) is:
System prefs: turn off all the multouch stuff. All the gestures. Off.
Also, battery life is low because this os constantly writes to the hard drive and uses the network card. If you happen to push the system while you hear the fans spin up as it receives a push notification ...panic.
Spotlight has big problems with Lion. I stopped it from indexing almost everything, installed quicksilver, then turned off indexing on the drive. I uninstall flash unless I need it also.
kernel panics for me would always feature AppleHWSensor in the panic log.
60% triggered by me using the expose show desktop guesture. However, I assigned that to a keystroke... works fine.
I've lost 3 hard drives to this garbage, ( you can't keep on just turning off modern unix systems, via kernel panic)
Try what I suggested:
No Flash until you need it.
Turn off all the multitouch stuff in trackpad prefs
stop spotlight from indexing your logs, and Caches. Then turn it off.

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

I want to run apple Hardware Test but can't find it on any CD's. I bought my iMac in 2009. I think it had 10.4 installed. It's not on my installation disk. Where can I find it?

I want to run Apple Hardware Text but can't find it on any CD's. I bought my iMac in 2009. It came with 10.4. Apple Hardware Test is not on the installation disk. Should I have it? Where can I find it? I"m now running 10.7.4.

The disc plainly state:
To use the AHT, hold down the D key as the computer starts up.
Works here. However, there was an issue with installing Lion that screwed this process up.
Mount disc 2, run this command in the Terminal app, OPTION-click & hold Finder's Dock icon, and select RELAUNCH:
defaults write com.apple.finder AppleShowAllFiles 1
That unhides all hidden files/folders.
Now, drill down to /"Applications Install\ Disc"/System/Library/CoreServices/ and drag the .diagnostics folder into your Lion boot volume's /System/Library/CoreServices/ folder. That might require you to authenticate to copy the folder into the CoreServices subfolder.
Run this command to hide the normally hidden files/folders and RELAUNCH the Finder again.
defaults write com.apple.finder AppleShowAllFiles 0
This should allow the machine to boot into AHT when restarting and holding down the D key.
If that doesn't do the trick, run this command in the Terminal app:
sudo chown -R root:wheel /System/Library/CoreServices/.diagnostics
At the Password: prompt, carefully type in your admin password, since nothing shows up on the screen, and hit the return key. Then, try another restart, holding down the D key.

Separate Apple Hardware Test DVD for MacBook Pro original??

Hey Folks, I'm trying to verify whether or not the MacBook Pro came with the Apple Hardware Test as a separate DVD disk. The "MacBook Pro" Install disk references it but I can't seem to find the software on that DVD. Any guesses out there would be appreciated. I'm about to perform an upgrade for Tiger to Leopard and wnat to give my laptop the "hairy eyeball" before I begin.
Many Thanks,
Peter

Insert the DVD and start up the computer with the D key held down. The Hardware Test is on a separate area of the DVD and isn't normally accessible.

I have a latest 2.7 EFI update but i still don't have the ATH(Apple Hardware Test) software! why is that so? do we have it on mountain lion?

So as u know the question
ill tell u the steps to try them out(no harm will be caused to u or ur com)
During restart-up press the D button before the gray screen appears and hold it for about a minute until u see a 4 or 6 bit image of old mac icon appear and then it loads u go select any language and click hardware test full and then tell me if it DOES HAPPEN ON OS X 10.8(mountain lion).
Thnx apple and u guys!

To use Internet Apple Hardware Test, start up your Mac and hold down both the option and D keys on your keyboard.

Can anyone tell me what apple hardware test error code apple hardware 4MOT/4/40000002: Exhaust-1153 or 1209 means? I am running a MacBook Pro.

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.

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.
https://discussions.apple.com/thread/3549995

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.
